It can be concluded from the analysis that utilization grade of basic farmland in current round was 16.82 without consideration of farmland gradation updating, and the grade enhanced by 0.08, still lower by 0.11 than that in last round, when the updating was taken into account. Finally, the reasons for problems occurred in the round were analyzed as follows： less consideration of protection on basic farmland in orientation of urban development; neglecting of basic farmland quality in Overall Plan of Land Utilization; non-classification of excellent lands after land consolidation; untimely updating of farmland gradation. In addition, the countermeasures were proposed correpondingly, including strengthening of basic farmland quality in the Plan, classification of excellent lands after consolidation, timely updating and inclusion of farmland gradation into ＂one map＂ project.展开更多

The solar reflectance, cooling performance, wash resistance, and film adhesion strength of the coatings were investigated. The influence of TiO2 powder gradation on the final properties of the coatings was studed. The solar reflectance and the thermal insulation were observed to increase with increasing content of nanosized TiO2. The mechanical properties of the coatings, such as their wash resistance and film adhesion strength, were observed to increase with increased incorporation of nanosized TiO2. Such improvements in the properties of the coatings were attributed to the greater specific surface area and lower thermal conductivity of nanosized TiO2 particles compared to normal TiO2 particles.展开更多

文摘The rapid development of digital financial inclusion is profoundly changing the financing environment for small and medium-sized enterprises(SMEs).As an important driver of economic growth and innovation,SMEs account for a significant share of employment and GDP globally.However,the traditional bank credit model has long failed to effectively meet the financing needs of SMEs due to issues such as information asymmetry,high cost,and difficulty in risk assessment,resulting in serious financing constraints.Digital financial inclusion,through technological innovation and big data analysis,has significantly reduced credit costs,alleviated information asymmetry,and provided SMEs with more flexible and efficient financing channels.Research shows that digital financial inclusion can not only ease the financing constraints of SMEs,but also promote their innovation and growth,providing important support for building a more inclusive and sustainable financial ecosystem.

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It is an important standard to judge the flood disaster in the basin whether the rainfall at the flood-inducing interface is reached.In this paper,the Xin'anjiang model,Topmodel model and SCS model were selected to calculate and compare the rainfall at the flood-inducing interface in the Zhanghe Reservoir basin in Hubei Province.The results showed that average relative error and average absolute error of Xin'anjiang model were-3.36%and-21.46×10^(5)m^(3),which were the minimum,followed by Topmodel model with 5.72%and 26.22×10^(5)m^(3),SCS model with 11.33%and 58.13×10^(5)m^(3).The minimum absolute error of the three hydrological models in calculating the rainfall at the critical interface was 3.26 mm,while the maximum was 49.24 mm.When the initial water level exceeded 120 m,the difference among the three models in calculating the rainfall at the critical interface became more and more obvious.When the reservoir water level was lower than 120 m,it mainly referred to the calculation results of Xin'anjiang model.When the reservoir water level was higher than 120 m,it mainly referred to the calculation results of Topmodel model.The research conclusion can provide reference for small and medium-sized basins selecting hydrological model to calculate the rainfall at the flood-inducing interface.
文摘The two-tier shareholding structure,which originated in the United States,has become popular around the world.Unlike the traditional model of“equal shares with equal rights”,the core feature of the two-tier shareholding structure is that the company issues two classes of shares with different voting rights.It enables the concentration and stabilization of corporate control,which has a positive effect on the long-term development of the company and resistance to hostile takeovers.Against the background of the rapid development of the capital market and the continuous innovation of corporate governance structure,the two-tier shareholding structure has begun to be adopted by many enterprises.While this structure can improve the efficiency of corporate governance and promote corporate growth,it also raises a number of challenges.In particular,for small and medium-sized shareholders,their shareholdings may face the problem of limited or no voting rights,as well as the lack of an effective internal and external monitoring mechanism for the company.These issues may lead to the impairment of the rights of small and medium-sized shareholders.Currently,challenges in practice include inadequate laws and regulations,insufficient disclosure of information,and inadequate monitoring mechanisms.Therefore,exploring the path to protect the rights and interests of small and medium-sized shareholders and analyzing their current situation has become an important area in the study of two-tier shareholding structures.This paper starts from the actual situation,analyzes the problems exposed in the operation process of two-tier shareholding structure,and then explores the practical and feasible methods to protect the rights and interests of small and medium-sized shareholders on this basis,with a view to putting forward valuable references for the development of China’s securities market.
文摘Taking B District in A City as an example, quality classification of basic farmland was evaluated based on farmland gradation. It can be concluded from the analysis that utilization grade of basic farmland in current round was 16.82 without consideration of farmland gradation updating, and the grade enhanced by 0.08, still lower by 0.11 than that in last round, when the updating was taken into account. Finally, the reasons for problems occurred in the round were analyzed as follows： less consideration of protection on basic farmland in orientation of urban development; neglecting of basic farmland quality in Overall Plan of Land Utilization; non-classification of excellent lands after land consolidation; untimely updating of farmland gradation. In addition, the countermeasures were proposed correpondingly, including strengthening of basic farmland quality in the Plan, classification of excellent lands after consolidation, timely updating and inclusion of farmland gradation into ＂one map＂ project.

文摘To optimize the energy output and improve the energy utilization efficiency of an aluminized explosive,an explosion device was developed and used to investigate the detonation pressure and temperature of R1(A16)aluminum powder and the aluminum powder particle gradation of R2(Al6+Al13),R3(Al6+Al24)and R4(Al6+AI flake)in a confined space.By using gas chromatography,quantitative analysis and calculations were carried out to analyze the gaseous detonation products.Finally,the reaction ratios of the aluminum powder and the explosion reaction equations were calculated.The results show that in a confined space,the quasi-static pressures and equilibrium temperature of the aluminum powder in air are higher than in vacuum.In vacuum,the quasi-static pressures and equilibrium temperatures of the samples in descending order are R1>R3>R4>R2 and R3>R4>R1>R2,respectively.In air,the quasi-static pressures and equilibrium telperatures of the samples in descending order are R1>R2>R4>R3 and R1>R4>R2>R3,respectively.R4(Al6+AI flake)and R3(Al6+A124)have relatively higher temperatures after detonation,which shows that the particle gradation method can enhance the reaction energy output of aluminum during the initial reaction stage of the explosion and increase the reaction ratio by10.6%and 8.0%,respectively.In air,the reaction ratio of AI6 aluminum powder can reach as high as 78.16%,and the reaction ratio is slightly reduced after particle gradation.Finally,the reaction equations of the explosives in vacuum and in air were calculated by quantitative analysis of the explosion products,which provides a powerful basis for the study of RDX-based explosive reactions.
文摘AIM:To evaluate the outcomes of patients withmedium-sized hepatocellular carcinoma(HCC)who underwent percutaneous microwave ablation(MWA).METHODS:We retrospectively reviewed all patients with a single medium-sized HCC who underwent percutaneous MWA from January 2010 to January2013.Technical success,technical effectiveness and complications were subsequently observed.Survival curves were constructed using the Kaplan-Meier method.The Cox proportional hazards model was fitted to each variable.The relative prognostic significance o f t h e va r i a b l e s fo r p re d i c t i n g ove ra l l s u r v i va l rate,recurrence-free survival rate and local tumor recurrence(s)was assessed using univariate analysis.All variables with a P value<0.20 were subjected to multivariate analysis.RESULTS:The study included 182 patients(mean age,58 years;age range:22-86 years)with a single HCC(mean size,3.72±0.54 cm;range:3.02-5.00cm).The estimated technical effectiveness rate was93%in 182 patients.The major complication rate was2.7%(5/182),including liver abscess in 4 cases,and abdominal bleeding at the puncture site in 1 case.Thirty-day mortality rate was 0.5%(1/182).One patient died due to liver abscess-related septicemia.Cumulative recurrence-free survival and overall survival(OS)rates were 51%,36%,27%and 89%,74%,60%at 1,2,and 3 years,respectively.Age(P=0.017)and tumor diameter(P=0.029)were independent factors associated with local tumor recurrence.None of the factors had a statistically significant impact on recurrence-free survival.Serum albumin level(P=0.009)and new lesion(s)(P=0.029)were independently associated with OS.CONCLUSION:Percutaneous MWA is a relatively safe and effective treatment for patients with medium-sized HCC.

文摘This study was designed to evaluate the thermal performance and mechanical properties of coatings with different gradations of TiO2 pigments. The solar reflectance, cooling performance, wash resistance, and film adhesion strength of the coatings were investigated. The influence of TiO2 powder gradation on the final properties of the coatings was studed. The solar reflectance and the thermal insulation were observed to increase with increasing content of nanosized TiO2. The mechanical properties of the coatings, such as their wash resistance and film adhesion strength, were observed to increase with increased incorporation of nanosized TiO2. Such improvements in the properties of the coatings were attributed to the greater specific surface area and lower thermal conductivity of nanosized TiO2 particles compared to normal TiO2 particles.

文摘Gradation equation is one way to describe the gradation of coarse-grained soil conveniently,exactly and quantitatively.With the gradation equation,the influence of gradation on the mechanical behaviors of coarse-grained soil can be expressed quantitatively.A new gradation equation with a parameter is proposed.The basic properties and applicability of the new equation are studied.The results show that the proposed equation has the applicability to express coarse-grained soil gradation(CSG),and the range of the parameter β is found to be 0<β<1.The value ofbdetermines the gradation curve shape.If β>0.5,the gradation curve is sigmoidal,otherwise the gradation curve is hyperbolic.For well graded gradations,the parameter has the value of 0.13<β<1.Several CSGs used in domestic and foreign earth-rockfill dams are probed,and the value of the parameterbfalls in the range of 0.18 to 0.97.The investigation of the range of β is of value to guide the design for CSG of earth-rockfill dam.

文摘The mass-front velocities of granular flows results from the joint action of particle size gradations and the underlying surfaces.However,because of the complexity of friction during flow movement,details such as the slope-toe impedance effects and momentum-transfer mechanisms have not been completely explained by theoretical analyses,numerical simulations,or field investigations.To study the mass-front velocity of dry granular flows influenced by the angle of the slope to the runout plane and particle size gradations we conducted model experiments that recorded the motion of rapid and long-runout rockslides or avalanches.Flume tests were conducted using slope angles of 25°,35°,45°,and 55° and three particle size gradations.The resulting mass-front motions consisted of three stages:acceleration,velocity maintenance,and deceleration.The existing methods of velocity prediction could not explain the slowing effect of the slope toe or the momentum-transfer steady velocity stage.When the slope angle increased from 25° to 55°,the mass-front velocities dropped significantly to between 44.4% and59.6% of the peak velocities and energy lossesincreased from 69.1% to 83.7% of the initial,respectively.The velocity maintenance stages occurred after the slope-toe and mass-front velocity fluctuations.During this stage,travel distances increased as the angles increased,but the average velocity was greatest at 45°.At a slope angle of 45°,as the median particle size increased,energy loss around the slope toe decreased,the efficiency of momentum transfer increased,and the distance of the velocity maintenance stage increased.We presented an improved average velocity formula for granular flow and a geometrical model of the energy along the flow line.
