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 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，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。

Aiming at the currently shortage of XML streams quality detecting, this paper proposes a new forecasting method of XML streams quality by least squares support vector machines, which is used the method of XML keys' vector matrix as windows, and vector product wavelet transform to multilevel decompose and refactor the XML streams series, that can fulfill real-time checking demand of XML quality, and ensure constraint, consist- ency and integrality. For even more adapting net load, it proposes a control strategy by weight and adaptive adjustment to ensure XML streams quality.

针对当前XML数据流质量检测存在的不足，提出构建XML键的矢量矩阵作为窗口，利用矢量积小波变换多级分解与重构XML数据流，再结合最小二乘支持向量机对XML数据流质量进行预测的一种方法，满足XML数据流质量重构时实时检测的要求，保证XML数据的约束性、一致性与完整性；为了更好的适应网络负载，采取加权与自适应窗口调整等调度策略充分保证XML数据流的质量检测。
