As the Yellow River, China's second longest river, reaches Maqu, the water it carries accounts for just 20% of the total water volume of the Yellow River.

中国的第二长河黄河刚流到玛曲时携带的水量只占黄河总水量的20%。

Because it's really all a completely gargantuan network of tributaries that are all connected over time forming what is absolutely an undisputedly the largest river in terms of total water volume in the world.

因为它真的就是一支庞大的支流网络，随着时间的推移，所有支流都连接在一起，形成了一条无可争议的世界上最大的河流。

This is particularly interesting, because normally, in classical fluid simulations, if our grid resolution is insufficient, we typically encounter water volume dissipation, which means that the total amount of mass in the simulation decreases over time.

这特别有趣，因为一般在经典流体模拟中，如果网格方案有所不足，我们将会遇到的典型问题是水的体积损耗，这意味着模拟中的总质量会随着时间的推移而减少。
