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。

It was suggested that contractility and pumping function of LV had a strong ability in reservation. 7. With increased HR, there was a decreasingly decrease in FTVI and TTVI and a significant compansatory increase in APFV、ATVI and AFF (HR＜100BPM) and in peak flow velocity (HR≥100BPM). 8. There was no differences between males and females in cardiac function.

Experimental results show that with given double swirl and direct pneumatic-valve and detonation tube structure, the decrease of partial detonable mixture filling proportion causes a little decrease of the peak value of detonation waves' pressure ,but impulse per unit volume of detonable mixture increases linearly.

研究结果表明，在气动阀选定、爆震管长度和爆震管内部结构一定条件下，随着脉冲爆震发动机可爆混气充填爆震管比例的降低，虽然爆震波压力峰值略有下降，但是，单位体积可爆混气获得的冲量线性增加，提高了脉冲爆震发动机的工作性能。
