mass balance

基本解释

But, the retreat of a glacier’s “snout” is only one of three measures of how glaciers can change. The other two are its “mass balance” and the rate at which melt-water is discharged.
但是，对冰川末端缩退速度的测量只是冰川变化的三种测量方法之一，另外两种是冰川的“质量平衡”测算法和融水排放速度测算法。

What I am going to do next day is go into the larger stoichiometry and understand the principles of mass balance and reactivity But before you go,hold it,I don't want you racing off.
下堂课我要做的是,讨论化学计量学，和,质量平衡很反应定律,但在下课之前，我不希望你们这么快走。
