air permeability testing的意思|示意

We also assemble a set of permeability testing equipment, by which we study on the effect of density, thickness and air pressure on the relative permeability.

并利用自行组装的测试设备研究了柔性石墨板密度、厚度以及空气压力差对相对透气系数的影响。

In this tests, the coefficient of permeability of the high air entry disk base of GDS unsaturated Triaxial testing system is also demarcated.

试验过程中还对GDS系统的陶土板底座渗透系数进行了标定。
