v0 And there is an angle between ; the position vector and v zero; 0 I call that phi zero.

在方位向量和,之间，有一个夹角;,我们叫它φ

I know v zero x, that is v zero cosine alpha xt=t so x of t is v zero cosine alpha times t but there is no acceleration, so that's it.

并且v0x=v0cosα,那么可有得出,因为没有加速度，所以就是这样了。

Normally I couldn't do that Vdp because this term would have p dV plus V dp, but we've specified the pressure is constant, so the dp part is zero.

一般情况下我不能这么写,因为这一项会包含pdV和，但是我们已经假定压强为常数，所以包含dp的部分等于零。
