Meanwhile seven hydrocarbon expulsion types and three accumulation types are classified based on the top surface features of source rock , and the relationships between source rock - block and carrying faults , respectively 根据源岩断块的特点及其顶面构造特征，划分了七种不同的源岩断块排烃类型。
The variation of stress and deformation fields in the freezing zone of an earth embankment is analyzed , and the effect of different frost - heaving zones on the deformation and stress of embankment surface is calculated 分析了土基范围内冻胀带对路基应力场和变形场的作用，并计算了不同冻胀带范围对路基顶面变形场和应力场的影响。
Lastly establish theoretical , industrial threshold value of organic enrichment of source rocks and grading evaluation criterion under different source rocks thickness , hydrocarbon potential , superface depth conditions 建立了不同厚度、不同生烃潜力、不同顶面埋深条件下烃源岩的有机质丰度理论下限、工业下限及分级评价标准。
At first , the propagation and influence of stress wave on the top of the pipe pile were discussed in the paper and a formula was obtained about the time difference between two initial signals which were received from two different points 本文首先研究了应力波在管桩顶面的传播及其影响，并提出了计算不同点激励速度峰值时间差的关系式。
Top - directly as a basis and foundation of the bearing surface as the top - embedded steel bearings or bearing surface , the supporting surface , the anchor bolt ( anchor ) position should be consistent with the allowable deviation of norms 基础顶面直接作为柱的支承面和基础顶面预埋钢板或支座作为柱支承面时，其支承面、地脚螺栓（锚栓）位置的允许偏差应符合规范的规定。
Pillow top : provides a traditional layer of surface comfort . often looks like a pillow , expertly tailored to prevent crowning , and the enhanced edge support virtually eliminates the sensation of roll - off 为紧的表面以枕头上面感受。舒适室内装饰品欧洲顶面上部层数被加入对床垫,而不是一个分开地被修建的片断。剪裁提供更加膨胀的睡觉表面没有加冠的专家,同时减少伴侣翻身时相互影响并加大睡眠面积。
Abstract : by means of the basic climatic principle and the local astronomical parameters the optimal dip angle , maximum wind pressure borne by the roof material , the depth of the cold - proof ditch and the suitable distance between the greenhouses in chengdu area are calculated 文摘:应用气侯学基本原理,当地天文参数与气候资料,计算了成都地区节能日光温室采光面最佳倾斜角,顶面覆盖材料承受最大风压,防寒沟深度及温室间适宜距离。
This paper presents checking method of using predigested formula to calculate construction deflection checking value of base according to the strength of the semi - rigid base materials increases with their age ; and advances pavement base construction deflection value checking criterion , provides checking basis for controlling pavement construction 本文在考虑半刚性基层材料强度随龄期增长规律的基础上，提出采用简化公式计算路面基层顶面施工弯沉值的检验方法；并结合宁夏公路路面典型结构，提出路面基层施工弯沉值检验标准，为控制路面施工质量提供了检测依据。
