B=0 There's going to be some temperature where B is equal to zero. In that case, your gas is going to look awfully like an ideal gas.
在某个温度,这时,实际气体的表现,十分接近理想气体,高于这一温度它是正的。
We just treated the one case of an ideal gas as the temperature is reduced.
我们只是讨论了温度下降时,理想气体的行为。
In this case it relates the volume to the pressure and the temperature.
现在假想我们需要用,理想气体定律来设计一台机器。
Now if you're at the temperature which is b higher than the inversion temperature, in that case here, a over RT is small compared to b, and this is going to turn out to be negative.
T>Tinv】,这时a/bR小于,结果是负数,因此如果温度。
