结果：溶剂沉积物明显提高了丹参酮的溶出度；丹参酮以结晶形式沉积于载体表面，结晶颗粒与沉积前相比明显减小，且出现大量针状微晶；丹参酮与载体间仅仅是物理作用。

In hypothalamic median eminance of kidney Yang deficiency group, the bounds of ependymocytes were dim, distribution of their microvillus changed, the top of microvillus enlarged and became spherical, and holes occurred on the surface of the cells. In that of control group, the cell arranged in order and the cell bouns were clear, the microvillus were equal in thickness and in long, thin acerose thread wool shape. The surface ultrastructure of ependymocytes on hypothalamic median eminance in herb group was similar to that of control group.

肾阳虚大鼠垂体内分泌细胞和甲状腺细胞存在着不同程度的粗面内质网、高尔基体扩张，线粒体空化，细胞变形，核固缩等超微结构的损伤；中药组大鼠垂体超微结构与正常组类似，细胞形态完整，结构清晰，细胞器结构正常，含有各种大小不等、形态不一的分泌颗粒，但甲状腺细胞超微结构与肾阳虚组相比未见明显改善。

Experts'research on the stability of water-based ink and process has been a preliminary study. Femandez and other matozoa of the discovery of water-based ink by electrostatic repulsion stability and space steric 's. Aromtics and gecol, and so on the surface of the plastic film studies indicate that water-based inks, join different types of surfactants can be effective removal of water-based inks, and Canadians zephiramine hexadecyl alkyltrimethylammonium can make the surface charge of carbon black particles.

国际学者差火性油墨的稳不退性和脱除工艺已举行了开端查究。femandez等发掘火性油墨的胶体稳不退性是由静电排不引力和不满答位阻效应成群不决的。gecol等差脱除塑料薄膜暗不天的火性油墨查究后暗示，参加差别种类暗不天活性剂均可灵验去除火性油墨，而且加人阳离子暗不天活性剂十六烷基不一甲基溴化铵可以使炭暗粒子暗不天电荷逆转。

The nylon was activated with organic functional groups,and after that reacted with high-molecular-weight polyethyleniminein the organic soleent. PEI was grafted covalently on the surface of nylon. The PEI grafted on the surface of nylon was modified by the alkyl halide such as bromohexane and iodomethane,to give high-molecular-weight antimicrobial quaternary ammonium salts.

摘 要：尼龙6用4-溴丁酰氯活化，再与高分子聚乙烯亚胺在有机溶剂中进行反应，使PEI共价接枝在载体上，然后用卤代烷对接枝在尼龙6上的PEI进行烷基化反应，使其形成具有杀菌功能的高分子季铵盐，制备出尼龙树脂固定化的高分子抗菌杀生剂。
