Based on the general model of the cost-reducing R＆D, the strategic interactions of output and R＆D investment between labor-managed firms in a duopoly are analyzed. Moreover, the impact of absorptive capacity effects on optimal output in the production stage is discussed. In the R＆D stage, the impacts of absorptive capacity effects on the equilibrium R＆D investment in cooperative and non-cooperative R＆D are analyzed. Finally, the R＆D strategy of labor-managed firms is compared with the behavior of profit-maximizing firms. The results show that equilibrium R＆D investment is always higher than that in the exogenous spillover rate, which is similar to the behavior of the profit-maximizing firms. However, unlike the profit-maximizing firms, the impact of the absorptive capacity that affects the relationship between the optimal output and its own（rival＇ s）R＆D is shown to be dependent upon a return-to-scale of the production.展开更多

[Method] Effect of LaCl3 on absorptive capacity to formaldehyde of four indoor ornamental plants was studied through fumigating in laboratory. Simultaneously, the indoor ornamental plant, which could significantly en- hance the degradation capacity of formaldehyde, was screened out to study the physiological and biochemical mechanisms of formaldehyde resistance. [Result] The ability to absorb formaldehyde of four indoor ornamental plants was enhanced by dif- ferent ranges after spraying with LaCl3 at suitable concentrations. The ability to ab- sorb formaldehyde of Hedera nepalensis var. sinensis, Chlorophytum comosum, Scindapsus aureun and Sansevieria trifasciata increased by 15.16%, 4.72%, 19.75% and 7.68%, respectively. In the four indoor ornamental plants, the capacity of S. au- reun to absorb formaldehyde was greatly improved by spraying LaCl3. When S. au- reun was stressed by formaldehyde, its chlorophyll content decreased by 39.87%, membrane permeability, MDA accumulation and POD activity increased by 8.17%, 56.92%, and 11.32%, respectively. However, compared the pre-spraying group with the no-spraying group under formaldehyde stress, chlorophyll content of S. aureun reduced less, membrane permeability and MDA cumulative both increased less, but POD activity increased more. [Conclusion] The formaldehyde absorption capacity of S. aureun was mostly improved after LaCl3 was sprayed.展开更多

[Method] With Scindapsus aureus as the test subject, 110 households of 20 communities in the New District of Nantong were selected to investigate formaldehyde concentration in indoor air; and effect of LaCl3 on absorptive capacity to formaldehyde of Scindapsus aureus was studied through fumigating in laboratory. Simultaneously, its physiological and biochemical mechanism of formaldehyde resistance was studied. [Result] The re- sults showed that formaldehyde pollution of indoor air was serious in the New District of Nantong, and the degree of pollution was related to the time after decoration. The suitable concentration of LaCl3 for Scindapsus aureus was 20 mg/L. The ability to ab- sorb formaldehyde of Scindapsus aureus, which was calculated by per unit leaf area, was enhanced after spraying the suitable concentration of LaCl3 by 19.75%. When Scindapsus aureus was stressed by formaldehyde, chlorophyll content decreased by 39.87%, membrane permeability and cumulative MDA amount increased by 8.17% and 56.92%, respectively, and POD activity increased by 11.32%. However, by com- paring the group pre-sprayed with LaCl3 and the group not sprayed with LaCl3 under formaldehyde stress, chlorophyll content of Scindapsus aureus reduced lessly, mem- brane permeability and MDA both increased lessly, while POD activity increased more. [Conclusion] This study provides a new thinking direction for broadening of rare earth application and control measures of indoor air pollution.展开更多

We propose the concept of IT absorptive capacity from an organizational level. A dynamic process model is developed to further analyze IT absorption. IT absorptive capacity of this process is embodied as six forms： identification, adoption, adaptation, acceptance, infusion, and knowledge management. By means of questionnaire surveys of 76 Chinese enterprises, the main factors that favor or disable the capacity of each stage are discovered. Using the method of system dynamics, a conceptual model of IT absorptive capacity is developed to analyze the action mechanism of the factors in detail. The model indicates that the critical factors are embodied in the aspect of management. Furthermore, it demonstrates that IT absorption is a spiral process, during which IT absorptive capacity evolves dynamically and, consequently, promotes IT use.展开更多

[Method] With 4 flue-cured tobacco cultivars as the experimental materials, their absorption capacity for 6 kinds of heavy metals was compared by pot experiment. [Result] There were great differences in absorption capacity of different flue-cured tobacco cultivars for the six kinds of heavy metals. According to the absorption capacity of different flue-cured tobacco cultivars for the heavy metals, the six heavy metals could be classified into three categories. The first category included only Cd with average enrichment coefficient of 8.564; the second category included Hg with average enrichment coefficient of 0.753; and the third category included Cr, As, Pb and Cu with average enrichment coefficients below or equivalent to 0.114. [Conclusion] The absorption capacity of different flue-cured tobacco cultivars for heavy metals was grasped by this study, thereby providing reference data for screening of high-yielding and high-quality flue-cured tobacco cultivars.展开更多

Research and technological competences are key indicators for the absorptive capacity of sustainability technologies and for the ability to export them. These issues are analyzed empirically for Brazil, Russia, India, China and South Africa (BRICS). Sustainability related research in BRICS is mostly carried out within broader, more sector oriented programmes. Specialization patterns of international patents and in foreign trade indicate various strengths and weaknesses of the BRICS countries. The differences within the countries imply that the analysis must proceed at a technology specific level. China has considerable capabilities in technologies such as photovoltaics, solar thermal or buildings. There is a strong need for strategic positioning of the countries and for coordination of the various policy fields involved.展开更多

Experiments of simultaneous desulfurization and denitrification were carried out using fixture bed and duct injection. The influencial factors for the absorptive capacity of the absorbent were studied. The absorptive capacities of 120.7 mg for SO 2 and 43.7 mg for NOx were achieved at a Ca/(S+N) molar ratio 1.2, respectively, corresponding removal efficiencies of 87% and 76%, while spent absorbent appeared in the form of dry powder. The optimal temperature and humidity of flue gas treated with this process were shown to be approximately 50℃, and 5% respectively. The mechanism of removal for SO 2 and NOx was investigated. In comparison with traditional dry FGD, this process appears to have lower cost, less complicated configuration and simpler disposal of used absorbent. The valuable references can be provided for industrial application by this process. The foreground of application will be vast in China and in the world.展开更多

文摘This study explores the intricate relationships among absorptive capacity,innovation,and financial performance in nonfinancial firms.Using data from COMPUSTAT spanning 1966 to 2020,including 25,392 observations,Tobin's Q is used as a measure of financial performance.Absorptive capacity,measured by the ratio of research and development expenses to total revenue,has a significant positive direct impact on both innovation and financial performance.However,innovation,represented by the natural logarithm of total intangible assets,has a negative influence on financial performance and mediates the positive relationship between absorptive capacity and financial performance.This reveals the suppressive role of innovation in the absorptive capacity-financial performance relationship.This challenges the conventional belief that innovation invariably leads to improved financial outcomes,highlighting the nuanced dynamics involved.The study underscores the trade-offs between short-term gains and long-term potential,emphasizing the complexity of organizational success in today's competitive landscape.

文摘In order to examine the problem of how to improve the use of information technology （IT） in enterprises, this paper makes an exploration from the perspective of organizational absorptive capacity. We propose the concept of IT absorptive capacity from an organizational level. A dynamic process model is developed to further analyze IT absorption. IT absorptive capacity of this process is embodied as six forms： identification, adoption, adaptation, acceptance, infusion, and knowledge management. By means of questionnaire surveys of 76 Chinese enterprises, the main factors that favor or disable the capacity of each stage are discovered. Using the method of system dynamics, a conceptual model of IT absorptive capacity is developed to analyze the action mechanism of the factors in detail. The model indicates that the critical factors are embodied in the aspect of management. Furthermore, it demonstrates that IT absorption is a spiral process, during which IT absorptive capacity evolves dynamically and, consequently, promotes IT use.

文摘This study aims to determine the variation and controlling factors of shale gas adsorption capacity in reservoirs in the Upper Ordovician Wufeng Formation and the Lower Silurian Longmaxi Formation(also referred to as the WF-LMX formations),South China.Based on data obtained using scanning helium ion microscopy(HIM)and nitrogen(N_(2))and methane(CH_(4))adsorption experiments,this study analyzed the organic pore heterogeneity of shales in the WF-LMX formations in well A and its effect on shale gas adsorption.Using the Frenkel-Halsey-Hill(FHH)model,data from N_(2) adsorption experiments were converted into fractal dimensions,which can reflect the complexity and heterogeneity of organic pores while also serving as a novel indicator for quantitatively assessing the pore structure complexity.The results indicate that shales in the WF-LMX formations in well A can be divided into two sections:(Ⅰ)the Wufeng Formation and the lower Longmaxi Formation(depths:ca.2871.0-2898.6 m),and(Ⅱ)the upper Longmaxi Formation(depths:<2871.0 m).Organic pores in Section Ⅰ typically exhibit complex internal structures,coarse surfaces,and interconnectivity,whereas those in Section Ⅱ are simple,smooth,and isolated.Moreover,the former possesses larger specific surface areas(SSAs)than the latter.A fractal analysis reveals that organic pores in the shale sequence can be classified into micropores(<2 nm),mesopores(2-10 nm),and macropores(>10 nm).The calculated fractal dimensions show greater heterogeneity of organic pores,especially macropores,in Section Ⅰ compared to Section Ⅱ.The results also reveal that organic macropores are the primary pores controlling the SSAs of organic pores in shale reservoirs in the WF-LMX formations.Organic pores in Section Ⅰ manifest a superior shale gas adsorption capacity compared to Section Ⅱ.The heterogeneity of organic pores might affect the adsorption capacity of shales in the formations.Generally,organic macropores in Section Ⅰ of the shale sequence exhibit more complex structures and larger SSAs,leading to a stronger absorption capacity of shale reservoirs in Section Ⅰ compared to Section Ⅱ.

文摘[Objective] This study aimed to analyze the differences in absorption capacity of different flue-cured tobacco cultivars for chromium （Cr）, arsenic （As）, cadmium （Cd）, lead （Pb）, mercury （Hg） and copper （Cu）. [Method] With 4 flue-cured tobacco cultivars as the experimental materials, their absorption capacity for 6 kinds of heavy metals was compared by pot experiment. [Result] There were great differences in absorption capacity of different flue-cured tobacco cultivars for the six kinds of heavy metals. According to the absorption capacity of different flue-cured tobacco cultivars for the heavy metals, the six heavy metals could be classified into three categories. The first category included only Cd with average enrichment coefficient of 8.564; the second category included Hg with average enrichment coefficient of 0.753; and the third category included Cr, As, Pb and Cu with average enrichment coefficients below or equivalent to 0.114. [Conclusion] The absorption capacity of different flue-cured tobacco cultivars for heavy metals was grasped by this study, thereby providing reference data for screening of high-yielding and high-quality flue-cured tobacco cultivars.

文摘A silylated melamine sponge(SMS)was prepared by two simple steps,namely,immersion and dehydration of a melamine sponge coated with methyltrichlorosilane.The silylated structure of SMS was characterized by FT-IR(Fourier-transform infrared)spectroscopy,SEM(Scanning electron microscopy)and in terms of water contact angles.Its oil-water absorption and separation capacities were measured by FT-IR and UV-visible spectrophoto-metry.The experimental results have shown that oligomeric silanol covalently bonds by Si-N onto the surface of melamine sponge skeletons.SMS has shown superhydrophobicity with a water contact angle exceeding 150°±1°,a better separation efficiency with regard to diesel oil(by 99.31%(wt/wt%)in oil-water mixture and even up to 99.99%(wt/wt%)for diesel oil in its saturated aqueous solution.Moreover,SMS inherited the intrinsicflame retardancy of the melamine sponge.In general,SMS has shown superhydrophobicity,high porosity,excellent selectivity,remarkable recyclability,and better absorption capacity for various oils and organic solvents,and a high separation efficiency for oil in saturated aqueous solutions.
文摘For the development process in the rapidly growing economies, knowledge transfer and technology cooperation are becoming important issues. Research and technological competences are key indicators for the absorptive capacity of sustainability technologies and for the ability to export them. These issues are analyzed empirically for Brazil, Russia, India, China and South Africa (BRICS). Sustainability related research in BRICS is mostly carried out within broader, more sector oriented programmes. Specialization patterns of international patents and in foreign trade indicate various strengths and weaknesses of the BRICS countries. The differences within the countries imply that the analysis must proceed at a technology specific level. China has considerable capabilities in technologies such as photovoltaics, solar thermal or buildings. There is a strong need for strategic positioning of the countries and for coordination of the various policy fields involved.

文摘This paper focuses on how technology services can help small and medium-sized enterprises(SMEs)overcome the digital transformation dilemma of“cannot transform(lack of know-how),dare not transform(fear of risk),and have no money to transform(lack of funds).”Using literature analysis and multiple case comparisons,the study summarizes five major categories of technology services:technical support,consulting and planning,training and empowerment,resource integration,and financing connectivity.It constructs a“service–capability–performance”catalytic framework.Tracking of 58 enterprises in the Yangtze River Delta reveals that resource integration contributes the most to digital maturity,with absorptive capacity playing a significant mediating role;the configuration of“high technology services+high absorptive capacity+high environmental dynamism”is a sufficient condition for high transformation performance.Based on these findings,countermeasures are proposed,including improving the technology service system,strengthening government-industry-academia collaboration,and optimizing funding and talent supply,providing replicable experience for SMEs,governments,and technology service institutions.

文摘Background Cetobacterium somerae,a symbiotic microorganism resident in various fish intestines,is recognized for its beneficial effects on fish gut health.However,the mechanisms underlying the effects of C.somerae on gut health remain unclear.In this experiment,we investigated the influence of C.somerae(CGMCC No.28843)on the growth performance,intestinal digestive and absorptive capacity,and intestinal structural integrity of juvenile grass carp(Ctenopharyngodon idella)and explored its potential mechanisms.Methods A cohort of 2,160 juvenile grass carp with an initial mean body weight of 11.30±0.01 g were randomly allocated into 6 treatment groups,each comprising 6 replicates(60 fish per replicate).The experimental diets were supplemented with C.somerae at graded levels of 0.00(control),0.68×10^(9),1.35×10^(9),2.04×10^(9),2.70×10^(9),and 3.40×10^(9)cells/kg feed.Following a 10-week experimental period,biological samples were collected for subsequent analyses.Results Dietary supplementation with C.somerae at 1.35×10^(9)cells/kg significantly enhanced growth performance,intestinal development,and nutrient retention rate in juvenile grass carp(P<0.05).The treatment resulted in increased intestinal acetic acid concentration and enhanced activities of digestive enzymes and brush border enzymes(P<0.05).Furthermore,it reduced intestinal permeability(P<0.05),preserved tight junctions(TJ)ultrastructural integrity,and increased the expression of TJ and adherens junctions(AJ)biomarkers at both protein and transcriptional levels(P<0.05).Mechanistically,these effects may be correlated with enhanced antioxidant capacity and coordinated modulation of the RhoA/ROCK,Sirt1,and PI3K/AKT signaling pathways.The appropriate supplementation levels,based on weight gain rate,feed conversion ratio,the activity of serum diamine oxidase and the content of lipopolysaccharide,were 1.27×10^(9),1.27×10^(9),1.34×10^(9)and 1.34×10^(9)cells/kg,respectively.Conclusions C.somerae improved intestinal digestive and absorptive capacity of juvenile grass carp,maintained intestinal structural integrity,and thus promoted their growth and development.This work demonstrates the potential of C.somerae as a probiotic for aquatic animals and provides a theoretical basis for its utilization in aquaculture.

文摘This study investigated the microstructure and hydrogen absorption properties of a rare-earth high-entropy alloy(HEA),YGdTbDyHo.Results indicated that the YGdTbDyHo alloy had a microstructure of equiaxed grains,with the alloy elements distributed homogeneously.Upon hydrogen absorption,the phase structure of the HEA changed from a solid solution with an hexagonal-close-packed(HCP)structure to a high-entropy hydride with an faced-centered-cubic(FCC)structure without any secondary phase precipitated.The alloy demonstrated a maximum hydrogen storage capacity of 2.33 H/M(hydrogen atom/metal atom)at 723 K,with an enthalpy change(ΔH)of-141.09 kJ·mol^(-1)and an entropy change(ΔS)of-119.14 J·mol^(-1)·K^(-1).The kinetic mechanism of hydrogen absorption was hydride nucleation and growth,with an apparent activation energy(E_(a))of 20.90 kJ·mol^(-1).Without any activation,the YGdTbDyHo alloy could absorb hydrogen quickly(180 s at 923 K)with nearly no incubation period observed.The reason for the obtained value of 2.33 H/M was that the hydrogen atoms occupied both tetrahedral and octahedral interstices.These results demonstrate the potential application of HEAs as a high-capacity hydrogen storage material with a large H/M ratio,which can be used in the deuterium storage field.

文摘Carbon dioxide(CO_(2))is the predominant greenhouse gas in the Earth’s atmosphere and plays a crucial role in global warming.Given the inherent limitations of monoethanolamine absorbents in current commercial large-scale CO_(2)capture applications,amino acid ionic liquids(AAILs)have garnered extensive interest in this field due to their adjustable structure,low volatility,high thermal stability,and significant absorption capacity.However,the number of comprehensive reviews recently published on the CO_(2)absorption by AAILs remains limited.In addition,researchers have differing opinions on the AAILs/CO_(2)reaction mechanisms.Therefore,this review provides a thorough overview of the reaction mechanisms and structure-activity relationships associated with AAILs for CO_(2)capture.Moreover,it outlines the research advancements in pure AAILs and their mixtures,including aqueous AAILs and AAIL-organic solvent mixtures.The effects of varying ionic structures and additives on the absorption properties of AAILs are examined in detail.In conclusion,although AAILs exhibit high CO_(2)absorption loading and possess numerous appealing characteristics,further research is essential to comprehensively evaluate their viability for large-scale CO_(2)capture from flue gas.

文摘Adsorbents with three-dimensional porous structures have gained widespread attention due to their unique characteristics,including a large surface area,high porosity,and excellent absorption capacity.One of the products is the wood sponge.The key to successfully producing wood sponges lies in an optimal multistage delignification process,which is particularly influenced by wood species,solvent,time,and temperature.The aim of this research was to analyze the characteristics of wood sponge derived from sengon wood(Falcataria moluccana Miq.)after multistage delignification.The process involved delignification using NaOH and Na_(2)SO_(3) solutions at 100℃ for 8,9 and 10 h,followed by further delignification in H_(2)O_(2) solution at 100℃ for 1,2,3,and 4 h.The samples were then frozen at -20℃ for 24 h and freeze-dried at -53℃ for 48 h.The results showed that wood sponges treated at 100℃ exhibited lower density,larger pore diameters,brighter color,and superior absorption capacity compared to untreated wood and sponges treated at room temperature for 24 h.FTIR analysis confirmed a decrease in wavelength between 1032–1035 cm^(-1),indicating the degradation of hemicellulose and lignin.XRD analysis revealed that crystallinity increased as amorphous content decreased with prolonged delignification.The wood sponges demonstrated good porosity,with an absorption capacity ranging from 0.65 to 2.24 g/g.The optimal treatment suggested in this research was multistage delignification using NaOH and Na_(2)SO_(3) solution for 10 h,followed by a 1 h treatment with H_(2)O_(2) solution.

文摘Triply periodic minimal surface(TPMS)structures,characterized by special repeating 3D surface periodically with an average curvature of zero in threedimensional directions,have a wide range of applications.Laser powder bed fusion(LPBF)technique,as a type of additive manufacturing techniques,provides the capability to fabricate such complex-shaped porous TPMS structures.In this study,Ti6Al4V G-sheet TPMS structures with various unit cell sizes were fabricated using LPBF to investigate the structural and material anisotropy and their effects on the anisotropy in energy absorption capacity by combining the finite element simulations and experimental analysis.The results showed that the TPMS structures can be successfully fabricated using LPBF,although the sheet thickness exceeds the designed values,with deviation decreasing as the unit cell size increases from 2 to 4 mm.The inherent anisotropy during the LPBF process results in variations in structural dimension,materials characteristics,and energy absorption capacity between directions parallel and perpendicular to the build direction.The anisotropic ratio of the LPBFed Ti6Al4V G-sheet TPMS structures increases from 1.5 to 2.2 in the structural dimension and from 2.8 to 3.3 in specific energy absorption per unit mass(SEA_(m))respectively with decreasing the unit cell size from 4 to 2 mm.The anisotropy of SEA_(m) primarily originates from the coupling effects of anisotropic dimensions and material properties in the LPBFed G-sheet TPMS structure.Among these factors,anisotropic material properties play a more significant role compared to dimensional anisotropy.
文摘The highly active absorbent with oxidization based on fly ash, lime and additive was prepared. Experiments of simultaneous desulfurization and denitrification were carried out using fixture bed and duct injection. The influencial factors for the absorptive capacity of the absorbent were studied. The absorptive capacities of 120.7 mg for SO 2 and 43.7 mg for NOx were achieved at a Ca/(S+N) molar ratio 1.2, respectively, corresponding removal efficiencies of 87% and 76%, while spent absorbent appeared in the form of dry powder. The optimal temperature and humidity of flue gas treated with this process were shown to be approximately 50℃, and 5% respectively. The mechanism of removal for SO 2 and NOx was investigated. In comparison with traditional dry FGD, this process appears to have lower cost, less complicated configuration and simpler disposal of used absorbent. The valuable references can be provided for industrial application by this process. The foreground of application will be vast in China and in the world.
