The weakly singular integral equation sued to solve the problem ofthe curved crack crossing the boundary of the antiplane circularinclusion is presented. Using the principal part analysis method ofthe Cauchy type integral equation, the singular stress index at theintersection and the singular stress of angular Regions near theintersection are obtained. By using the singular stress obtained, thestress intensity factor at The intersection is defined. After thenumerical solution of the integral equation, the stress intensityfactors at The end points of the crack and intersection areobtainable.

The interaction between multiple curved rigid line and circular inclusion in antiplane loading condition is considered in this paper. By utilizing the point force elementary solutions and taking density function of traction difference along curved rigid lines, a group of weakly singular integral equations with logarithmic kernels can be obtained. After the numerical solution of the integral equations, the discrete values of density functions of traction difference are obtainable. So the stress singularity coefficient at rigid line tips can be calculated, and two numerical examples are given.

Thermogenesis is a process of heat production in living organisms. It is rare in plants, but it does occur in some species of angiosperm. The heat is generated via plant mitochondrial respiration. As possible involvement in thermogenesis of mitochondrial factors, alternative ox- idases （AOXs） and plant uncoupling mitochondrial proteins （PUMPs） have been well studied. AOXs and PUMPs are ubiquitously present in the inner membrane of plant mitochondria. They serve as two major energy dissipation systems that balance mitochondrial respiration and uncoupled phosphorylation by dissipating the H~ redox energy and proton electrochemical gradient （A#H~） as heat, respectively. AOXs and PUMPs exert similar physiological functions during homeothermic heat production in thermogenic plants. AOXs have five isoforms, while PUMPs have six. Both AOXs and PUMPs are encoded by small nuclear multigene families. Multiple isoforms are expressed in different tissues or *** studies have been done in the area of thermogenesis in higher plants. In this review, we focus on the involvement and regulation of AOXs and PUMPs in thermogenesis.

科学分析区域耕地集约利用时空分异及影响因素,对于促进耕地资源集约潜力挖掘和高效利用具有重要现实意义。以长江经济带作为研究案例地,从投入强度、利用强度、产出效率及持续状况等维度上构建耕地集约利用评价指标体系,运用投影寻踪模型定量测度1978-2016年长江经济带耕地集约利用水平;基于流域、省域、市域多尺度视角,通过变异系数、ESDA、GIS模型,探究长江经济带耕地集约利用多尺度时空分异格局;运用地理探测器模型揭示长江经济带耕地集约利用分异的影响机制。结果表明:1)1978年以来流域尺度上长江经济带耕地集约利用水平表现提升态势,但演化过程中呈现"东高西低"差异特征;省域、市域尺度上长江经济带耕地集约利用呈现空间集聚特征,并且尺度越小空间集聚越显著。2)研究期间省域、市域尺度空间关联类型均以正向相关为主,且市域尺度上长江经济带耕地集约利用存在空间集聚"俱乐部趋同"现象,表现为H-H(high-high)型主要集聚在上海及苏南地区,并逐渐向绍杭、皖江地区演化;而L-L(low-low)型主要集聚在川西高原区。3)自然因素、人口增长、经济社会发展及制度政策可有效解释长江经济带耕地集约利用时空分异,其中人口因素、经济社会因素对耕地集约利用分异影响显著,而政策因素呈现较强驱动效应。4)最后从开展土地综合整治、加大要素投入力度、优化调整耕地结构、推进农业科技创新等方面提出促进长江经济带耕地集约利用提升政策建议。
