This law needs to watch the trend of the step on face of CdSe crystal cleavage only, can determine the C axis direction of CdSe crystal, namely the C axis direction that the direction with the outspread step on cleavage face is CdSe crystal, used law of X ray diffraction to undertake test and verify to the result.

此法只需观察CdSe晶体解理面上台阶的走向，便可确定CdSe晶体的C轴方向，即解理面上台阶延伸的方向为CdSe晶体的C轴方向，并采用X射线衍射法对结果进行了验证。

The cooling crystallization and the polymorphic transition processes of L-Serine in aqueous solution were real time monitored by PVM and FBRM. The results show that at a higher temperature, the anhydrous crystals form in club-shaped habit, while the temperature of the slurry was cooled under the polymorphic transition temperature, the club-shaped anhydrous crystals would translate to the hexagonal plate-shaped monohydrate crystals.

Results show that the morphology of HNS changes from short plane-like shape to long plane-like shape when non-solvent temperature changes from 25℃ to 50℃. The morphology comes through the variety of ellipsoid, short plane-like and club-shaped with pH value of non-solvent from acidity to neutral and finally basical, with the particle size distribution in 50-300 nm, 50-500 nm, and 50-600 nm, respectively. Ellipse plane-like and long club-shaped morphology HNS were obtained using white dextrine and sodium carboxymethyl cellulose as surfactants in non-solvent, with the particle size distribution in 50-300 nm and 50-600 nm.
