Third, hydration of AH in dissoluble sulfate complies with dissolve-nucleate -grow theory, concentration of Ca~2+ from dissolving of CaSO_4 is higher than one of CaSO_4·2H_2O, calcium sulphate dihydrite gets a motivity of crystallization. dissoluble sulfate takes the following function: double-salt or dissoluble sulfate hydrate from hydration of AH in it becomes heterogeneous particle and a kind of nucleation catalyzer, and reduces surface barrier when DH becomes crystal because the crystal of DH precedently appears in uneven place. Results indicate hydration of AH does not conform with double-salt theory, but it conform with this mechanism: dissolve-nucleate-grow, formation of DH is an uneven nucleation and crystalizaion process.

Solubility and stability of calcium arsenates under different CO2 pressures are studied based on the data of precipitation and solution experiments simulated by PHREEQC program. The result shows that calcium arsenates can dissolve incongruently by the effect of CO2 in high pH（pH〉8. 3）and make their solubility higher. The higher the CO2 pressure is, the lower the acidity of the incongruent dissolution is.

By dehydrochlorination reaction the poly[(2-methoxyl-5-octyloxy)phenylene vinylene] is synthesized and the material"s structure is characterized by nuclear magnetic resonance spectroscopy, infrared absorption spectrum, ultraviolet and visible spectrophotometry. At the meantime, the fluorescence spectrum is measured and the mechanism of fluorescence occurring is analyzed. Thermal Gravimetric Analyzer"s results show that the MO-PPV"s thermal stability is fine. Also the experiment of resolvable property indicates that the MO-PPV can well dissolve in chloroform. Through analyzing the film"s surface by Metaloscope and Atomic Force Microscope, the good filming is found.
