On the permanent of Hermite triple diagonal matrix

关于Hermite 三 对角 矩阵的积和式

The internal iterative calculation is to correlate the equations of mass and phase equilibrium into a triple diagonal matrix from which the liquid compositions can be found out .

即内层迭代是将物料平衡方程和相平衡方程联立，化为 三 对角 矩阵 形式，由之解出各板液相组成后，通过泡点计算法求定各板新的温度和相平衡常数。
