monovariant system

Firstly, all of univariant line equations are attained; secondly, a crossing point ( φ i , pH i ) is got by solving univariant line equations including a main component(M i ) one another; thirdly, φ i is compared with the chemical potentials φ of other components in this crossing point by chemical potentials minimization.

提出了一种新的绘制φ—ｐＨ 图的方法， 即先求出所有的单变线方程， 再选取某一种组分Ｍｉ 为主组分， 把含有该组分的所有单变线方程两两求解， 求出交点（ φｉ ，ｐＨｉ） ， 然后用化学势约束原理法， 将主组分同其它组分在该点的化学势作比较， 若前者的化学势小于后者， 则该点为所求的三相点。

Firstly, all of univariant line equations which are based on chemistry model are attained.

即依据化学模型求出单变线方程 ,选取某一种组分M为主组分 ,把含有该组分的所有单变线方程两两求解 ,求出其交点 (Eh ,pH) ,根据三相点的涵义和电化学意义 ,三相点若稳定 ,则在该点至少有 3个不同的组分共存 。

At first , the artificial neural network(ANN) models with nonlinear time series are established , then time series for single variable and multiple variables are studied with the models.

首先构造出人工神经网络非线性时序模型 ,然后用该模型进行单变量和多变量时间序列预报研究。
