pressure gradient effect的意思|示意

The birefringent effect of K9 glass has been studied under low pressure. The index of birefringence and its gradient have been measured.

研究K9玻璃在低压下的双折射效应，测量它的双折射率及其梯度。

It is indicated that the main factors affecting low permeability gas reservoir are stress action, start-up pressure gradient, permeability, slippage effect, and water blocking effect etc.

结果表明影响低渗气藏的主要因素有应力作用、启动压力梯度、渗透率、滑脱效应、水锁效应等。

The method can be extended to axisymmetric and three-dimensional turbulent boundary layers if the pressure gradient effect is considered.

如果考虑压力梯度的影响，还可以将该方法推广到轴对称和三维湍流边界层中去。
