pressure decline

During breeding for vertical resistance, horizontal resistance tends to decline because of negative selection pressure.

当培育垂直抗性时,由于负的选择压力, 水平抗性趋于下降.

more people will be looking for jobs and the pressure on employers to raise wages to attract workers will decline.

由于有更多人求职，企业在提升薪资吸引员工方面的压力便随之下降。

A new analytical model for pressure decline under the condition of forced fracture closure was developed on the basis of material balance theory and the former corresponding fracture models, such as PKN and KGD models.

以物质平衡原理和相关分析模型为基础，对PKN和KGD两种裂缝模型建立了裂缝强制闭合条件下的压力降落解释模型。
