提出了对于定容吸附储存，吸附剂比表面大小的比较应以单位体积吸附剂的比表面为基准。

It was also suggested that the comparison of the surface area should be based on per volumetric adsorbent.

所有测量单位例如功率、压力计、温度计、体积测量、舱容测量等均采用公制。

All measuring units such as power, pressure gauge, thermometer, volume gauge, tanks scales etc., to be in accordance with metric system.

We can measure the heat capacity at constant volume, and now we have another term, and if we can figure out how to measure it, we'll have a complete form for this differential du which will enable us to calculate du for any process.

我们能够测量恒定体积下的热容，这里我们有另一项，如果能够知道怎么测量它，问我们就有了这个完整的微分式,就能够对任何过程计算。

T So we know that T dS/dT at constant volume is Cv over T, T and dS/dT at constant pressure is Cp, over T.

在恒定压强下定压比热容Cp乘以dT除以,所以在恒定体积下dS/dT等于Cv除以，在恒定压强下dS/dT等于Cp除以。
