mass conservation的用法和樣例：
例句
- Under these conditions the conservation of energy is equivalent to the conservation of mass.
在這種條件下，能量守恆和質量守恆是相等的。 - The computational results show that, compared with CM, FVM is less dependent on mesh density and has smaller error in calculating mass conservation.
還分析了兩種方法對網格密度的依賴性和質量守恆計算誤差，顯示有限體積法均優於特徵線法。
