水泥混凝土路面破坏类型及其原因的探讨

水泥混凝土路面的破坏类型有多种，其中裂缝，变形，接缝，表面层等四类破坏是最常见的破坏类型。本文在总结分析这四类破坏类型的基础上，对其产生的主要原因进行了深入的探讨。     

Holling's Figure-Eight Model: A Technical Reevaluation in Relation to Climate Change and Biodiversity

Holling proposed a four-phase conceptual model of ecosystem dynamics that includes exploitation, conservation, and destructive and renewal components to explain the failure of many natural resource management schemes. The model is drawn as a sideways figure-eight i.e. . There are two dimensions in this model, connectivity (abscissa) and the amount of capital stored in the system (ordinate). This conceptual model has been suggested as a guide to thinking about the impact of climate change on biodiversity, but the two dimensions are insufficient and the alignment of the figure-eight model is problematic when compared with actual data. Kay has adjusted the dimensions of the figure-eight model and renamed the abscissa as exergy stored and the ordinate as exergy consumed. We realign the original figure-eight model, labeling the abscissa as carbon stored and the ordinate as nutrients, such that the relative values of both axes are in qualitative agreement with data from four different studies. This new alignment is then shown to fit relatively well with Holling's original labels. This revision of the figure-eight model brings Holling's model into agreement with observations and provides insight into the linkages between biodiversity and climate change.     

Investigation of Synthesis of Copolymers from the Waste Products of Industrial Oil Refinement having Adhesion Properties and Strength to the Thermal Destruction

In this study, the waste products of industrial vegetable oil refinement were transformed into the glycidyl ester for preventing the effects of them to the environment, the ways for evaluating them in polymer chemistry were investigated, copolymers having high adhesion property and strength to the thermal destruction were synthesized and the area of their usage was determined. For this reason, the waste product of sunflower oil refination as a vegetable oil in the industry; soap stock (SS) was converted to the unsaturated glycidyl esters by the interaction with epichlorohidrine in the alkaline medium. After that the copolymerization of synthesized unsaturated glycidyl esters and the other waste product of oil refinement fatty acid (FA) with styrene in the radicalic initiator medium were investigated and copolymers that have high strength to the thermal destruction and adhesion property were synthesized. From the results of TGA and DTA analysis, it was determined that synthesized copolymers have low loss of weight at high temperature. The structures of copolymers were fixed by spectral and chemical analysis methods.

浅析高技术局部战争对环境的破坏

高技术局部战争有空袭与反空袭和以中远程精确打击为主导的非接触作战的特点。但由于现代战争武器精良、爆炸威力强大，对大气、水、动植物、土壤等生态环境和人类造成了广泛、深重和久永的环境灾难，并引发了沙尘暴、地震、臭氧层破坏和放射性污染等一系列环境恶化。为此，提出了从体制支持、技术支持和舆论支持方面开展战损环境修复思路。

物种灭绝的若干种可能的序

利用集合种群共存动力模式，研究了由于栖息地毁坏而导致物种灭绝的顺序问题．研究结果表明：在群落里各物种种群具有相等的死亡率的假设下，栖息地毁坏而导致物种的灭绝存在3种最基本可能的顺序，既最弱物种与最强物种相伴灭绝，最强物种与最弱物种是强弱交替灭绝，以及由强而弱依次灭绝．参7
