原始试样析出晶体为针状莫来石和少量石英，粒径在0.1μm左右，正交实验中最佳试样主要析出晶体为片状莫来石和Ca9Al(PO4)7，粒径在1μm左右，添加滑石试样主要析出晶体为板粒状莫来石和Mg3Al2(SiO4)3，粒径在0.5~1μm。

The results show that in the case of {1 0 0}, the morphology of crystal changes from lowtemperature sheet to hightemperature tower with increasing the synthesized temperature, whereas in the case of {1 1 1} the change trend is contrary to {1 0 0}. When {1 1 1} facet or {1 1 1} was used as the growth facet, the sheetlike crystal is more difficult to incorporated for the metal inclusion regardless of synthesized temperature. With NiMnCo metal as solvent, large highquality gemgrade diamonds can also grow on {1 1 1} facet with proper temperature gradient.

由此可见，PEG链段对胶束的影响越小，PCL嵌段的影响越大，越趋向于形成片状晶体结构。

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.
