Of the 145 listeners, 38 had face-to-face interviews. These listener groups were asked to listen to the recordings of the four English varieties and fill in a cloze test.Results indicated that the three listener groups differed significantly in rating comprehensibility of American English, Moroccan English and Chinese English but they did not give Turkmen English statistically different ratings;there were no significant differences in accentedness ratings except for Chinese English;and there were significant differences in the intelligibility scores of the four English varieties. In addition, with respect to seven linguistic variables-speed, clarity, intonation,smoothness and fluency, vocal intensity, pause, vocabulary and grammar, there were significant differences in three listener groups’ rating of six variables in American English except the one of“speed”. By contrast, Chinese English received significantly different ratings only in “proper speed”. No differences were found in the ratings for Moroccan English and Turkmen English.Finally, unlike Chinese listeners without international experiences, native listeners and Chinese listeners with international experiences shared some similarities in correlations between the ratings of accentedness and comprehensibility and those of linguistic variables on Moroccan English,Turkmen English, and Chinese English. However, the results for American English from Chinese listeners without international experiences and native listeners seemed to be more alike. Linguistic variables correlating with accentedness and comprehensibility of American English showed a mixed profile. Qualitative data provided more variant elaborations on the pronunciations and language uses of the speakers.展开更多

文摘Currently,the International Maritime Organization(IMO)has approved and implemented the assessment requirement for Minimum Propulsion Power(MPP)of ships in adverse sea conditions.The assessment method and relevant influence factors will have a vital impact on ship's design and operation.On the other hand,MPP is essentially a criterion for manoeuvring safety at actual seas.However,the practical assessment methods adopted in IMO guidelines do not directly and accurately account for ship's coursekeeping ability in severe seas.A time-domain comprehensive method with supplementary course-keeping ability criteria has been proposed in the authors'preliminary research.Based on an updated mathematical model and criteria,this paper presents more detailed elaborations,results and discussions on the time-domain method,including the comparative analyses with a power line method and two steady-state equilibrium methods based on IMO guidelines and draft.Discussions on the influences of key factors,involving criterion conditions and calculation parameters,are also presented.The results indicate that different methods exhibit varying advantages and complexity in MPP assessment,thus constituting a multi-level assessment framework for MPP.In particular,the time-domain comprehensive assessment has a higher accuracy with more realistic description of manoeuvre behaviors,capable of offering a solution for the ships that cannot meet other assessments,or for the assessment requiring additional course-keeping ability.Furthermore,an expanded range of wave direction sets a stricter but potentially necessary requirement,while using the self-propulsion factors at low speeds can eliminate the unnecessary conservation of assessment result caused by those at design speed.

文摘[Objectives]To identify the drought resistance of main wheat varieties in Shandong Province and screen suitable cultivars for dryland cultivation.[Methods]Employing eight varieties including Jimai 60 as test materials,this study simulated drought stress using 20%PEG-6000 and measured changes in germination-stage indicators.A comprehensive evaluation was conducted using the membership function method,incorporating relative coleoptile length,relative germ length,relative radicle length,relative germination rate,relative germination potential,and stress germination index.[Results]Drought stress not only reduced wheat seed germination rate but also inhibited the growth of the germ,coleoptile,and radicle.The D values of the eight varieties were ranked as follows:Jimai 60>Linmai 9>Yannong 999>Shannong 30>Shannong 28>Luyuan 502>Yannong 1212>Jimai 22.Based on D values,the eight dominant wheat varieties were classified into three categories:highly drought-resistant varieties(Linmai 9 and Jimai 60),moderately drought-resistant varieties(Yannong 999 and Shannong 30),and sensitive varieties(the others).Linmai 9 and Jimai 60 are recommended as suitable wheat varieties for dryland cultivation in Shandong Province.[Conclusions]Drought stress induced by 20%PEG-6000 reduced germination rate,germination potential,and germination index of wheat varieties while inhibiting the growth of coleoptiles and radicles.These indicators can provide a preliminary assessment of drought resistance in wheat cultivars.However,since filter paper was selected as the growth medium,root length measurement errors were introduced during root washing,leading to variations in final experimental results.Futuer studies could attempt using sterilized sand as an alternative growth medium.

文摘Objective:To explore the effect of comprehensive nursing on relieving psychological pressure in patients with pulmonary micro-nodules.Methods:One hundred and twenty patients with pulmonary micro-nodules who received diagnosis and treatment in our hospital from January 2024 to December 2024 were randomly divided into control and observation groups.The control group received routine nursing,while the observation group received comprehensive nursing.The Self-Rating Anxiety Scale(SAS)and Self-rating Depression Scale(SDS)were used to evaluate the patients’psychological states before and after nursing.Patient satisfaction with nursing was analyzed using a nursing satisfaction survey scale.Results:After nursing,the SAS and SDS scores of the observation group were significantly lower than those of the control group(P<0.05).The nursing satisfaction rates of the observation and control groups were 98.33%and 83.33%,respectively,with statistically significant differences(P<0.05).Conclusion:Comprehensive nursing intervention for patients with pulmonary micro-nodules can effectively relieve their psychological pressure and improve nursing satisfaction,demonstrating clinical value.

文摘Comprehensively revealing the intensity of drought propagation from meteorological to hydrological drought is crucial for effective drought monitoring and management.However,existing assessments often fail to integrate multiple drought characteristics,resulting in incomplete evaluations.To address this limitation,this study introduced the drought comprehensive propagation intensity(DCPI)index,a systematic tool that quantifies propagation intensity and incorporates five drought characteristic indicators(drought frequency,total duration,maximum duration,coverage,and degree)to assess the comprehensive drought intensity in the upper Shiyang River Basin,China from 1961 to 2023.The results indicated that pre-1980s drought propagation was relatively weak(DCPI<0.964),reflecting stable hydrological homeostasis.After the 1980s,the intensity significantly increased,peaking at 5.530(rather strong drought)in the 2000s due to human-induced alterations in surface runoff and ecological changes.Spatially,the western tributaries(e.g.,the Xida River Watershed)presented stronger hydrological drought intensity,whereas the eastern tributaries(e.g.,the Huangyang,Gulang,and Dajing river watersheds)presented higher meteorological drought intensity.The DCPI values decreased from west to east,with near peer-to-peer propagation observed in the Dongda,Huangyang,and Jinta river watersheds,suggesting minimal human interference.A nonlinear relationship between meteorological and hydrological droughts was identified,with severe drought frequency and duration emerging as critical drivers of propagation intensity.Notably,trends of meteorological humidification coexist with hydrological aridification,highlighting systemic challenges for water resource management.The DCPI framework enhances the understanding of drought mechanisms by enabling a structured evaluation of drought impacts,which is essential for developing effective water resource strategies and ecological restoration efforts in arid areas.This study underscores the importance of integrating multi-dimensional drought characteristics to improve prediction accuracy and inform policy decisions.

文摘Aeroengines,often regarded as the heart of aircraft,are crucial for flight safety and performance.Comprehensive performance evaluation of aeroengines supports Prognostics and Health Management(PHM)and aeroengine digital engineering.Due to their highly integrated nature,aeroengines present challenges in performance evaluation because their test-run data are high-dimensional,large-scale,and exhibit strong nonlinear correlations among test indicators.To solve this problem,this study proposes a unified framework of the comprehensive performance evaluation of aeroengines to assess performance objectively and globally.Specifically,the network model and the dynamics model of aeroengine performance are constructed driven by test-run data,which can explain the patterns of system state changes and the internal relationship,and depict the system accurately.Based on that,three perturbations in the model are used to simulate three fault modes of aeroengines.Moreover,the comprehensive performance evaluation indexes of aeroengines are proposed to evaluate the performance dynamically from two dimensions,the coupling performance and the activity performance.Thirteen test-run qualified and four test-run failed aeroengines are used to validate and establish the qualified ranges.The results demonstrate that the comprehensive evaluation indexes can distinguish test-run qualified and test-run failed aeroengines.By changing the dynamic parameters,the comprehensive performance under any thrust and inlet guide vanes(IGV)angle can be estimated,broadening the test-run scenarios beyond a few typical states.This novel approach offers significant advancements for the comprehensive performance evaluation and management of aeroengines,paving the way for future PHM and aeroengine digital engineering developments.
