Because the electric quantity of electron is negative, according to Lenz's right hand law, the metal electrons on conductor move to the direction, while the positive charges move to the direction, so the direction of current is shown in the graph.

由于電子的電量是負值亚洲成熟熟女一级毛片，根據(jù)楞慈右手定則无码乱伦国产，所以導體上金屬電子向著方向移動，正電荷向方向移動亚洲精品永久中文字幕，故電流的方向如圖中所示的方向操屄视。

Illustrations are used to analyze the limitation of line sampling firstly. For linear limit state, the efficiency of LS is affected by the dispersion of the actual important direction from the optimal one, the bigger the dispersion is, the lower the efficiency is. For non-linear limit state, in case that the actual important direction deviates from the optimal one greatly, the efficiency and the precision of LS decrease seriously, even wrong results are obtained.

At the same time, the MEMS geophone can be used to monitor the microseismic event of coal mining, water reservoir and hydraulic fracturing through the research of failure location and the ratio of rock fracture can be predicted by counting numbers of acoustic emission.After spent six months to monitor injecting microseism in Ying 11 block of DongXin field using this system and collect abundant microseismic wave files. The result showed that the orientation of injecting fracture was mainly NE90°to NE125°. The maximum horizontal principal stress directions were mainly distributed in NE90°-NE130°range. Analysis of numerical simulation result of reservoir stress in Ying 11 block showed that the maximum horizontal principal stress directions are approximate east-west in central and western region and approximate NE130°at eastern border.
