It tells particularly the debris flow"s the encironment and the development characteristic by numbers . And according to its character , selecting the latest research results at present , the anthor calculates the debris flow"s the moving , dynamical characteristics and the scale , such as , the velocity of flow , the wallop , the peak value flux , and the total flux . And the anthor calculates density in different design frequency by the empirical formula method . In the text, the author uses the modle of evaluating a single gully to evaluate the risk of the debris flow . First , the author calculates the hazard degree in different design frequency , and forecasts the risk range of debris flow in Shenjia gully based on the maximum pile thickness and the total solid amount of a denbris flow . Then , on the basis of the risk range in different design frequency , the author carries out the damageability and risk assessment . The basic purpose of risk management is reducing risk or transferring risk , reducing the loss of life and property . The text constructs the system of risk management of debris flow in Shenjia gully , basis on the condition of Shenjia gully .

本文从地形地貌、地层岩性、地质构造、气象水文等方面系统地阐述了深家沟泥石流的发育环境及发育特征；分别从形成区、流通区、堆积区对深家沟流域特征进行描述；依据泥石流沟自身特点，选用现阶段最新的研究成果，推算了不同设计频率下的深家沟泥石流流速、峰值流量、总流量、冲击力等动力特征和规模数据；并且根据经验公式法来确定深家沟不同设计频率下的泥石流容重；本文采用单沟泥石流风险评价模型对深家沟泥石流进行风险评价，首先对不同的设计频率下的深家沟泥石流进行危险度评价，根据最大堆积厚度与一次泥石流冲出量来预测不同频率下的泥石流危险范围，然后，根据预测的评估范围，评价对应范围内的易损度，最后作出风险评价；城镇泥石流风险管理的根本目的是降低风险或转移风险，减少生命财产的损失，本论文根据泸定深家沟泥石流的具体情况，构建了深家沟泥石流风险管理体系。

Polyether based polyurethanes are among the most interested polymers which have been used suitably for the biomedical applications, especially in cardiovascular system. In order to meet the requirements of the artificial heart program in our college, two sorts of polyether based polyurethane elastomers, PU-BD and PU-MC, were synthesized both based on prepolymer formed by the reaction of polytetramethylene ether glycol and diphenyl methane-4, 4′-diisccyanate, with 1, 4-butanediol and 3, 3′-dich...

本文介绍了两种聚醚型聚氨酯弹性体PU—BD和PU—MC的合成路线，两种弹性体的物理机械性能(曲挠、抗张强度、伸长率等)的测试结果，两种弹性材料的生物相容性试验(凝血时间，慢性组织相容性、细胞毒性等)及其结果、各种试验结果表明，这两种聚氨酯弹性材料的耐曲挠性能和生物相容性都已达到现阶段人工心脏研究工作的要求，为两种有希望的医用高分子材料。

Showing directiveness of level our country to plan formal choice ought to be policy supply, on the foundation that plans lesson of experience of two kinds of methods in summary mandatory planning and demand directiveness namely, solid inflict policy is mixed for oriented method the guiding plan that makes sure supply and photograph of demand structure balance suit.
