The load combination is complex with consideration of the effect of asymmetry distribution of live load, snow accumulation and horizontal seismic load.

且考虑了屋面活载不均匀效应、雪压堆积效应和水平地震作用的影响，荷载组合复杂。

Oil migrated from higher potential belts to lower ones in "centrifugal flow", which was the regional dynamic condition of controlling petroleum accumulation and distribution.

油气由高势区向低势区呈“离心”式运移，这正是控制油气呈环、带状聚集与分布的区域动力学条件。

The strong tectonic stress not only changes the reservoir properties but also directly controls hydrocarbon accumulation and distribution.

强烈的构造应力不仅改变了储层的性质，而且还直接控制着油气的聚集和分布。
