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。

This means the Galeb Duhr could hold a victory area on its own for some time and might even knock an opponent out of it; well worth doing on maps with shared victory areas.

这表示哥砣石人能独自守住胜利区持续一段时间，甚至将敌人推离胜利区。尤其在有共同胜利区的地图更好值得一推。

In the natural improved grassland with uncultured and resowed,the sorts of grass increased 5～8 varieties,and the height of elymus dahuricus and the sedge respectively was higher than that of the control area for...

在免耕补播改良天然草地方面，草地植被种类增加5～8种，披碱草高度较对照区高出18cm，苔草高出4cm，其总盖度较对照区高出近20%，而施肥试验草层高度较对照区增加了1.5cm，其盖度由55%增加至90%，增幅为35%。

After selective extraction, the cyst wall of two kind of resting cysts displayed a filament network. In the resting cysts of Tachysoma pellionella and Euplotes encysticus, the filament was located in mesocyst and endocyst respectively. On the other hand, a special filament scaffold region was observed below the cyst wall in two kind of cysts. Compared with the true IF which was located in central part of cyst, the filament of this region was net as well as uniform, and no any cytoplasm residue can be seen in this region. In the resting cyst of Euplotes encysticus, a filamental boundry which partitioned the special filament scaffold region and the true IF region was observed.

两类休眠包囊的包囊壁经生化分级抽提后均显示纤维结构，急纤虫休眠包囊中纤维定位于中间层，包囊游仆虫休眠包囊中纤维定位于内层壁；其次，在两类休眠包囊的包囊壁下，相当于细胞质表质层的位置，均有一个特殊的纤维网络区，与细胞质深层的网络区相比，此部分的纤维纯净、均匀，未见附着细胞器及细胞质残留物，在包囊游仆虫休眠包囊中此纤维网络区与真正的细胞质纤维网络之间由纤维构成的界膜隔开。

Experimental results show that rapid solidification technology can remarkably optimize Mg-Zn-Nd alloy's microstructure and property,there are three zones of fine grain zone,columnar grain zone and equiaxial grain zone in ribbon's solidification structure,which reserve structure character of cast-magnesium alloy.
