So we're going to want to know basically, dKp/ dT dK/ dT How does equilibrium constant, or dK/ dT, if you're doing solution, how does the equilibrium change with temperature?

我们根本上想知道的是，是多少，we，want，to，know，what，is，dKp/dT。，平衡常数或者，如果在溶液中，平衡怎样随温度改变？

But as a new technology, the existing DKP relatively few reported cases, follow-up time is shorter, it would need long-term clinical application of large sample to make a more objective evaluation of efficacy.

但作为一项新技术，现有DKP的报告病例数相对较少，随访时间较短，尚须长期的大样本临床应用才能作出比较客观的疗效评价。

Well, dKp/ dT is sort of like, we could also ask what's d log Kp dT.

好dKp/dT有点像，我们也可以问logdKp/dT是多少。
