| 1 | Ozone sensitivity analysis with the MM5-CMAQ modeling system for Shanghai显示文摘Ozone has become one of the most important air pollution issues around the world. This article applied both O 3 /(NOy-NOx) and H 2 O 2 /HNO 3 indicators to analyze the ozone sensitivity in urban and rural areas of Shanghai, with implementation of the MM5-CMAQ modeling system in July, 2007. The meteorological parameters were obtained by using the MM5 model. A regional emission inventory with spatial and temporal allocation based on the statistical data has been developed to provide input emission data to the MM5-CMAQ modeling system. Results showed that the ozone concentrations in Shanghai show clear regional differences. The ozone concentration in rural areas was much higher than that in the urban area. Two indicators showed that ozone was more sensitive to VOCs in urban areas, while it tended to be NOx sensitive in rural areas of Shanghai. | Li Li Changhong Chen Cheng Huang Haiying Huang Gangfeng Zhang Yangjun Wang Minghua Chen Hongli Wang Yiran Chen D.

| 2 | SURFACE STRESS EFFECT IN MECHANICS OF NANOSTRUCTURED MATERIALS显示文摘This review article summarizes the advances in the surface stress effect in mechanics of nanostructured elements,including nanoparticles,nanowires,nanobeams,and nanofilms,and heterogeneous materials containing nanoscale inhomogeneities.It begins with the fundamental formulations of surface mechanics of solids,including the definition of surface stress as a surface excess quantity,the surface constitutive relations,and the surface equilibrium equations.Then,it depicts some theoretical and experimental studies of the mechanical properties of nanostructured elements,as well as the static and dynamic behaviour of cantilever sensors caused by the surface stress which is influenced by adsorption.Afterwards,the article gives a summary of the analytical elasto-static and dynamic solutions of a single as well as multiple inhomogeneities embedded in a matrix with the interface stress prevailing.The effect of surface elasticity on the diffraction of elastic waves is elucidated.Due to the difficulties in the analytical solution of inhomogeneities of complex shapes and configurations,finite element approaches have been developed for heterogeneous materials with the surface stress.Surface stress and surface energy are inherently related to crack propagation and the stress field in the vicinity of crack tips.The solutions of crack problems taking into account surface stress effects are also included.Predicting the effective elastic and plastic responses of heterogeneous materials while taking into account surface and interface stresses has received much attention.The advances in this topic are inevitably delineated.Mechanics of rough surfaces appears to deserve special attention due to its theoretical and practical implications.Some most recent work is reviewed.Finally,some challenges are pointed out.They include the characterization of surfaces and interfaces of real nanomaterials,experimental measurements and verification of mechanical parameters of complex surfaces,and the effects of the physical and chemical processes on the surface properties,etc. | Jianxiang Wang Zhuping Huang Huiling Duan Shouwen Yu Xiqiao Feng Gangfeng Wang Weixu Zhang Tiejun Wang | 2011 | Acta Mechanica Solida Sinica2011，24，1： | 11 |

| 5 | Review and prospect of soil compound erosion显示文摘Soil erosion is one of the most serious environmental issues constraining the sustainable development of human society and economies.Soil compound erosion is the result of the alternation or interaction between two or more erosion forces.In recent years,fluctuations and extreme changes in climatic factors(air temperature,precipitation,wind speed,etc.)have led to an increase in the intensity and extent of compound erosion,which is increasingly considered in soil erosion research.First,depending on the involvement of gravity,compound erosion process can be divided into compound erosion with and without gravity.We systematically summarized the research on the mechanisms and processes of alternating or interacting soil erosion forces(wind,water,and freeze-thaw)considering different combinations,combed the characteristics of compound erosion in three typical regions,namely,high-elevation areas,high-latitude areas,and dry and wet transition regions,and reviewed soil compound erosion research methods,such as station observations,simulation experiments,prediction models,and artificial neural networks.The soil erosion model of wind,water,and freeze-thaw interaction is the most significant method for quantifying and predicting compound erosion.Furthermore,it is proposed that there are several issues such as unclear internal mechanisms,lack of comprehensive prediction models,and insufficient scale conversion methods in soil compound erosion research.It is also suggested that future soil compound erosion mechanism research should prioritize the coupling of compound erosion forces and climate change. | YANG Wenqian ZHANG Gangfeng YANG Huimin LIN Degen SHI Peijun | 2023 | Journal of Arid Land2023，15，9： | 0 |
| 6 | The 2023 Earthquake in Türkiye and Implications for China's Response to Catastrophe显示文摘On 6 February 2023,two 7.8 magnitude earthquakes consecutively hit south-central Türkiye,causing great concern from all governments,the United Nations,academia,and all sectors of society.Analyses indicate that there is also a high possibility of strong earthquakes with a magnitude of 7.8 or above occurring in the western region of China in the coming years.China is a country that is highly susceptible to catastrophic disasters such as earthquakes,floods,and other natural calamities,which can cause significant damages to both human life and property,as well as widespread impacts on the society.Currently,China's capacity for disaster prevention and control is still limited.In order to effectively reduce the impact of catastrophic disasters,ensure the safety of people's lives and property to the greatest extent possible,maintain social stability in high-risk areas,and ensure high-quality and sustainable regional development,it is urgent to improve the seismic resistance level of houses and critical infrastructure in high earthquake risk zones and increase the earthquake-resistant design level of houses in high-risk fault areas with frequent seismic activities;significantly enhance the ability to defend against extreme weather and ocean disasters in economically developed areas along the southeastern coast,as well as the level of fortification in response to extreme meteorological and hydrological disasters of coastal towns/cities and key infrastructure;vigorously enhance the emergency response capacity and disaster risk prevention level in western and ethnic minority regions;comprehensively improve the defense level of residential areas and major infrastructure in high geological hazard risk zones with flash floods,landslides,and mudslides;systematically promote national disaster prevention and mitigation education;and greatly enhance the societal disaster risk reduction ability,including catastrophic insurance. | Peijun Shi Lianyou Liu Weihua Fang Jifu Liu Jidong Wu Lu Jiang Bo Chen Gangfeng Zhang Hao Zheng Yintong Zhang | 2023 | International Journal of Disaster Risk Science2023，14，6： | 0 |
| 7 | Carbon Emission Risk and Governance显示文摘Within the hazard and disaster risk research field, explicitly treating carbon emissions as a hazard remains rather nascent. Applying hazard and disaster risk research perspectives to seek new insights on integrated mitigation and adaptation approaches and policy measures is equally elusive. Since China’s pledge to achieve carbon neutrality by 2060, the ‘‘dual carbon” goals of carbon emission peaking and neutrality have stimulated nationwide attention, research, and policies and action plans.How to ensure that the transition pathways are on track and well-contextualized is one of the crucial challenges for policymakers and practitioners. This article examines the‘‘risks” of missing the carbon neutrality goal at a regional scale in China, denoted as Carbon Emission Risk(CER).Carbon emissions(CE) as hazard, combined with the human socioeconomic system as exposure and human living environment, constitute the regional carbon emission environmental risk system. The ‘‘risks” of missing(or achieving) the carbon neutrality target for any region at any time, the article argues, is essentially determined by the ratio of CE to carbon absorption(CA, for uptake and removal). These variables are modified by a broadly defined ‘‘vulnerability coefficient”(Cv) that embodies both the potential for changes(decreasing CE and increasing CA), and the uncertainties of measuring CE and CA. Thus,the ratio of CE to CA is a measure of reality at any moment of time, whereas Cv indicates the overall propensity or capacity for moving the CE/CA ratio towards 1, that is,realizing carbon neutrality. Based on our calculation, CER at the provincial level in eastern China is higher than in western China. The article also calls for strengthening CER research and summarizes key measures for carbon emission risk governance. | Lu Jiang Xiaokang Hu Gangfeng Zhang Yanqiang Chen Honglin Zhong Peijun Shi | 2022 | International Journal of Disaster Risk Science2022，13，2： | 0 |
