接近音速的

In this article, the existence and uniqueness of the generalized solution of this boundary value problem are discussed, the existence and convergence of Galerkin's approximate solution is proved, and Linear dependence of the the error bound on M~2/(1-M~2) is also proved, where M is Ma...

本文证明了这类方程弱解的存在和Galerkin逼近解的存在和收敛，并且还给出了有限元解的误差估计，指出误差界线性地依赖于M~2/(1—M~2)。M为马赫数。也就是说，当流速接近音速时，有限元解的误差将无法控制。

What's more, as the vehicle approaches the speed of sound, it produces a frontal shock wave which liquefies the earth ahead, so the wheels end up carving through ground, rather than simply rolling over it.

更重要的是，由于车辆接近音速的，它产生正面冲击波的液化地球未来，所以车轮最终通过地面雕刻，而不是简单地在它滚动。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
