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。

So if you had a high temperature, this a small compared to b. If you're negative which means that dT/dp at constant H is less than zero.

高于反转温度，这一项相比于b很小,意味着H恒定时,偏T偏p小于零。
