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。

The survival curve of the population was between Deevey Ⅱ and Deevey Ⅲ with two peaks of mortality rate. Four functions (survival rate, mortality rate, mortality density function, hazard rate) all indicated that the population increased at the early stage and kept stable at the late stage.

Regardless to the research development or industrial application, nano metal powders are extensively discussed. Within these powders, the flammable and explosible nano aluminum, titanium and iron powders produce a great amount production and apply widely. Meanwhile, the surface/volume ratio of powders is increased significantly under nano scale, in which to enhance the ignition opportunity. Thus, the dust explosion hazard risk of nano powders could remarkable rise. In addition, the comparison of explosion phenomenon, test methods and quantification parameters between nano and micro scale is necessary to deeply investigate further. So that this project operates the explosion characteristic experiments to measure and determine such the maximum explosion pressure, minimum explosion concentration and explosion characteristic Kst value on above mentioned three nano metal powders. Expectantly, to provide the appropriate recommendations of safety prevention for nano dust explosion based on the experimental results.

奈米金属粉末无论是研究发展或是工业界应用,目前皆是广泛讨论研究之材料,其中,奈米铝粉、奈米钛粉以及奈米铁粉等可燃、爆性粉末,均有高额产量及大量应用领域,与此同时,在粉末粒径进入奈米尺度的情况下,粉尘比表面积大幅提升,增加此三种粉尘可被点燃的机会,因此,潜在的粉尘爆炸危害风险将广幅增加,另外,微米尺度粉尘爆炸的现象、测试方法以及量化参数是否具有相同的实验尺度基点,也需要深入探讨,故本次计画针对上述三种奈米金属粉末,进行三种不同粒径的爆炸特性参数实验,如最大爆炸压力、最低爆炸浓度以及爆炸特性参数Kst值之量测与计算,期能量化其粉尘爆炸特性,并据此提出适当的安全防护建议。
