我首先计算-,在你们的参照组中，你们所坐的地方-,失去了多少能量,这是完全非弹性碰撞。

So I will first calculate-- in your frame of reference, - where you are sitting-- how much energy is lost when we have a completely inelastic collision.

我开始计时，用和原来一样的方法，只是我现在做的是，完全非弹性碰撞。

And so now I will do the timing in exactly the same way that I did before, except that now I have a completely inelastic collision.

详细讨论、分析了涉及灾害性天气预报的理论模式的稳定性，这些模式包括：非静力完全弹性方程组、滞弹性方程组。

Stability related to theoretical model for catastrophic weather prediction that includes non-hydrostatic perfect elastic model, anelastic model was discussed and analyzed in detail.
