电镜形态学分析见造模两个月的糖尿病大鼠坐骨神经髓鞘板层有分离现象，线粒体嵴紊乱，有的线粒体嵴完全消失形成空泡线粒体，轴浆内有大量脂肪颗粒沉积；经电针和渴痹康治疗后能减轻这些病理改变。4。无论是电针治疗还是渴痹康治疗均无明显降血糖作用。

In this paper, a process of pressure-swing distillation for separation of HFC-245fa and HF azeotrope was simulated by Aspen Plus.

在计算机模拟和分析的基础上，研究了变压精馏分离五氟丙烷－氟化氢的工艺流程。

This separation of ethanol-water azeotrope using glycol as solvent is analyzed. The result shows that when the system is operated twice,the output is the greatest and the consumption is the least.

A new method to separate azeotropic mixtures was proposed in the paper, that is, vacuum volatilization separation process. It is undertaken in vacuum and the temperature must be controlled under the azeotropic point to avoid forming of azeotrope.

该过程在真空下操作，控制系统温度低于共沸点，使两组分在分离过程中不形成共沸物，而依靠组分间挥发速度及扩散速度的差异，来突破共沸限制，达到分离目的。

In the end, the extractive distillation method was applied to separate and purify the binary azeotrope mixture, methanol-dimethyl carbonate. The isoamyl acetate was used as extractant and the two tower system was introduced to continuous extractive distillation operation. The results show a better separation effect.

最后采用萃取精馏的方法，对甲醇-碳酸二甲酯的二元共沸混合物进行了分离提纯研究，以毒性较低的乙酸异戊酯为萃取剂，采用两塔连续萃取精馏操作，结果表明，分离效果比较理想。
