Thermodynamic factors in the experiment are analyzed,and the kinetic characteristics of CVD process of the high purity titanium at different deposition temperature, influence of the supersaturation of the vapor and the crystal temperature on the crystal active of the high purity titanium under different kinetics mechanism have been studied as well.

The results of the experiment indicate that the supersaturation is the main facto.

During the process of DKDP crystal growth, supersaturation is the dominating factor which greatly influence the growth and quality of DKDP single crystal.

The effects of supersaturations and temperatures on the habits of 6APA were investigated.

Soft Measurement of Sucrose Oversaturation by Using the Least Square Method;

Care must be taken not to exceed a critical oversaturation to prevent nucleation of new.

According to sugar refining technics, oversaturation of massecuite is the most prominence parameter of all ones, and it must be controlled to a certain degree during the process of whole crystallization.

Effect of sodium tripolyphosphate on the hydration process,ion concentration and supersaturation degree in liquid phase,and crystal morphology of building gypsum was systemically investigated.

In this paper,by using scanning electric microscope(SEM),mercury intrusion porosimetry(MIP),and atom adsorption spectrophotometer,the effect of citric acid on the hydrate process,ion concentration in liquid phase and supersaturation degree,crystal morphology of dehydrate,and microstructure of hardened paste of building gypsum were systemically studied.
