mass balance

基本解釋

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，對冰川末耑縮退速度的測量衹是冰川變化的三種測量方法之一，另外兩種是冰川的“質(zhì)量平衡”測算法和融水排放速度測算法。

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.
下堂課我要做的是,討論化學(xué)計量學(xué)，和,質(zhì)量平衡很反應(yīng)定律,但在下課之前，我不希望你們這麼快走。
