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。

After computing work, property tables of wet air were done based on equations of wet air properties included pressure, specific enthalpy, relative humidity, density and so on.

根据湿空气有关压力、焓、相对湿度、密度等状态参数计算公式，经过计算获得直观的湿空气性能参数表。
