When the integral constant is zero, the existence of smooth solitary wave solutions, uncountably infinite, many smooth periodic wave solutions, and kink and anti-kink wave solutions are proved.

在积分常数为零的条件下，证明了该方程存在光滑孤立波解、不可数无穷多光滑周期波解、扭结波和反扭结波解。

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。

And that implies that since the quantity we want is given by this quantity, which is zero times a constant, the quantity we want is also zero.

因为我们需要的量，是由这个量乘以一个常数，因为这个量是零，因此我们需要的量也是零。

Now for this experiment, this is a constant enthalpy experiment for the Joule-Thomson experiment, this is equal to zero.

对于这个实验，焦耳-汤姆逊实验,是一个焓不变的实验,焓变化等于0，所以我可以。

This is just an equality. I have a constant pressure dH process. This term here is equal to zero.

这是一个等式，这是个恒压过程,这项等于零，这意味着。

This piston is being brought out, so we expect 0 the work to be negative, negative. And we start o V2 ut with zero volume. We end up with a volume p2 of V2, and the external pressure is constant to p2.

所以我们可以想象功是负的,开始的时候体积是,最终的容积是,外界的压力恒为。
