The weather systems which cause the gales in the area are mainly cold wa- ve (cold front), low pressure zone in Mongolia(northeast), cyclone, typhoon and rainstorm.
引起本区域大风的天气系统主要有寒潮（冷锋）、蒙古（东北）低压、气旋、台风及雷雨。
This zone has the features of poor property, poor communication and low energy, and pressure is not affected by water injection well.
其特点是物性差、连通性差、能量小和压力不受注水井影响。
The heavy fogs of Shangqiu are formed by the weather situations: continental anticyclone, warm zone in front of cold front, uniform pressure field, and low pressure with an inverted trough.
商丘市的大雾多形成在大陆高压型、冷锋前暖区型、均压场型、(低压)倒槽型天气形势中。
The bump which is equal to the local boundary layer thickness in height can divert the boundary layer effectively. As a result, no obvious low total pressure zone is found at the outlet of the inlet;
进气道出口截面上未发现因附面层吸入而造成的低总压区，这说明高度与当地附面层厚度相当的进口鼓包能有效地隔除附面层中能量较低的气流；
The zone has the obvious features of low pressure, high saturation of condensate oil, high interfacial tension and high flowing velocity.
该区域明显地呈低压、高凝析油饱和度、高界面张力和高流速的特征；
Moreover, the separation zone is only a low-energy fluid gathering area for large total pressure loss and entropy rather than a zone of loss source.
分离区仅是高总压损失和高熵值的低能流体聚集区，而非高损失来源区；
The late stage is characterized by recrystallization in a stable enviroument. The metamorphism of low pressure type of low amphibolite facies only occurs on the main boundary planes of the zone.
晚期阶段以稳态重结晶为特征，仅在韧性滑脱剪切带主界面形成了低压型低角闪岩相的变质作用。
