The focus is on bird strike experiments and simulations. The explicit finite element software PAM-CRASH is employed to conduct bird strike simulations, and a coupled Smooth Particles Hydrodynamic（SPH） and Finite Element（FE） method is used to simulate the interaction between a bird and a target structure. The SPH method is explained, and an SPH bird model is established. Constitutive models for various structural materials, such as aluminum alloys, composite materials, honeycomb, and foam materials that are used in aircraft structures,are presented, and model parameters are identified by conducting various material tests. Good agreements between simulation results and experimental data suggest that the numerical model is capable of predicting the dynamic responses of various aircraft structures under a bird strike,and numerical simulation can be used as a tool to design bird-strike-resistant aircraft structures.展开更多

At the same time, the educational development of art design in colleges and universities has also become a common trend, for the shaping of the Chinese women's top of the artistic design concept has laid a good cornerstone. At the same time, the Chinese nation after five thousand years of development, the formation of the vast treasures of art and culture, in the origins of circulation is still endless, to the later Chinese children to provide valuable artistic learning resources. The fusion of Chinese folk art culture in the art design education of colleges and universities has a crucial influence on broadening students 'artistic vision, cultivating students' artistic innovation thinking and inheriting Chinese traditional folk art culture. Through the combination of folk art and modern art, the art education of colleges and universities has very far-reaching foresight significance.展开更多

文摘The growing presence of emerging pollutants in the environment has led to a focus on developing new treatment technologies to address the limitations of traditional methods.Recent advancements in combining photocatalysis with biodegradation for pollutant treatment have garnered significant attention.This is due to the rapid and uncontrolled chemical reactions in single photocatalytic processes,which often result in the buildup of harmful by-products and over-oxidation residues.Additionally,relying solely on biodegradation is challenging for breaking down emerging pollutants that possess high concentrations and intricate structures.Therefore,the intimately coupled photocatalysis and biodegradation(ICPB)systems,along with the photocatalytic microbial fuel cells(PMFCs),as a new approach to treat pollutants.These systems combine the benefits of biodegradation and photocatalytic reactions,providing cost-effective,eco-friendly,and sustainable solutions with significant promise.In order to demonstrate the ICPB system and the PMFCs system as rational options for pollutant removal,the mechanisms of pollutant degradation by the two systems have been analyzed in depth,and recent advances in photocatalysts,biofilms,and carriers/configurations in the two systems have been summarized.Furthermore,the practical applications of the ICPB system versus the PMFCs system for pollutant removal are also summarized and highlighted.This review further points out the current limitations,such as photocatalytic materials that are still challenging in terms of commercial viability for practical applications,and looks forward to the prospects of the ICPB system versus the PMFCs system for the treatment of pollutants to promote practical applications.

文摘A comprehensive understanding of vegetation responses to climate extremes is essential for predicting ecological risks.The Tianshan Mountains,the world's largest arid mountain system,are ecologically vulnerable to climate extremes,yet the spatiotemporal heterogeneity of vegetation responses is not well understood.To address this,we assessed changes in vegetation phenophases using the green-up date(GUD)and the monthly maximum vegetation index(MVI).Their relationship with climate extremes across seasons and geographic units was analyzed using Classification and Regression Tree and Principal Component Analysis.Results indicate that GUD advanced by 0.276 days/year,with MVI increasing in spring and decreasing in summer.On a yearly scale,nighttime heatwaves advanced GUD in all vegetation types at lower altitudes with higher snow cover,whereas daytime heatwaves delayed GUD in grasslands.On a monthly scale,early spring heatwaves generally benefitted vegetation,with positive effects decreasing from forests to grasslands:forests benefitted from March to May,forest-grassland from March to April,and grasslands only in March.By late summer,heatwaves were negatively correlated with MVI across all vegetation types.This study highlights the complex responses of vegetation to climate extremes and underscores the vulnerability of high-altitude,low snow-covered grasslands,which is crucial for guiding restoration efforts.
文摘Understanding how renewable energy generation affects electricity prices is essential for designing efficient and sustainable electricity markets.However,most existing studies rely on regression-based approaches that capture correlations but fail to identify causal relationships,particularly in the presence of non-linearities and confounding factors.This limits their value for informing policy and market design in the context of the energy transition.To address this gap,we propose a novel causal inference framework based on local partially linear double machine learning(DML).Our method isolates the true impact of predicted wind and solar power generation on electricity prices by controlling for high-dimensional confounders and allowing for non-linear,context-dependent effects.This represents a substantial methodological advancement over standard econometric techniques.Applying this framework to the UK electricity market over the period 2018-2024,we produce the first robust causal estimates of how renewables affect dayahead wholesale electricity prices.We find that wind power exerts a U-shaped causal effect:at low penetration levels,a 1 GWh increase reduces prices by up to£7/MWh,the effect weakens at mid-levels,and intensifies again at higher penetration.Solar power consistently reduces prices at low penetration levels,up to£9/MWh per additional GWh,but its marginal effect diminishes quickly.Importantly,the magnitude of these effects has increased over time,reflecting the growing influence of renewables on price formation as their share in the energy mix rises.These findings offer a sound empirical basis for improving the design of support schemes,refining capacity planning,and enhancing electricity market efficiency.By providing a robust causal understanding of renewable impacts,our study contributes both methodological innovation and actionable insights to guide future energy policy.

文摘The effects of the built environment factors on urban vitality have attracted wide attention in the urban planning fields in recent years,but few studies have considered the variables’relative importance and their nonlinear effects on urban vitality.Taking a Chinese metropolis—Hangzhou as a case study,this study applied the gradient boosting decision tree(GBDT)model to explore the nonlinear effects of the 5D factors of the urban built environment on urban social vitality and economic vitality and the importance of variables.The results show that the GBDT model has better goodness of fit than the traditional ordinary least squares(OLS)regression in the urban vitality models.The urban built environment plays an important role in affecting urban vitality,while built environment designs witness the most important effect.Specifically,the density of shopping facilities,medical facilities,and road networks are the most important factors affecting urban social vitality,while road network density,destination accessibility,and population density play the most important roles in affecting urban economic vitality.Finally,the urban built environment factors have nonlinear threshold effects on both urban economic and social vitality in Hangzhou,with differing nonlinear response patterns observed between social and economic dimensions.
