An empirical equation was obtained for explaining the relationship between streamer stability propagation field and relative air density, humidity.

通过数据拟合得到了流注稳态传播电场和相对空气密度以及湿度之间的经验公式。

The same period, the ocean thermal slow, relatively high temperature, air density changes smaller solipsism relative area of low pressure.

同一时期，海洋散热较慢，温度相对地较高，空气密度变化较小，遂形成相对的低压区。

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。
