On this basis, the principle of minimum energy and the equations of mass balance, electron balance and electric neutrality are applied to constructing a linear programming mathematical model and calculating the amount of mass transfer between water and rock with the simplex method. 在此基础上,利用能量最低原理和质量守恒、电子守恒、电中性方程来构造线性规划数学模型,并用单纯形法求得水-岩之间的物流量。
