This paper presents a novel method of stroke fragmentation, which combines geometric features and HMM(hidden Markov model).

Improved Marquart algorithm in studying on ternary phase diagram of casting solution;

Calculation of Ternary Phase Diagram of Polyethersulfone Casting Solution;

Recovery of ammonium thiocyanate by ternary phase diagram theory from coking waste water;

In order to develop a new solution crystallization process to separate the eutectics of musk ketone and musk xylene,the ternary phase diagrams of musk ketone,musk xylene and solvent were calculated.

According to the self-emulsification domains basing on the ternary phase diagrams and the mean diameter of three formulas,the optimum formula was screened initially.

The ternary phase diagrams of HPC/water/glycerol as well as binodal line and spinodal line were simulated based on Flory-Huggins\'s polymer solution theory using water as solvent and glycerol as nonsolvent, using the method of Matlab computer process for the first time.
