The main content and results are showed as follows:(1)Chitosan was degraded by high pressure homogenization, and its effect increased with molecular weight of original chitosan, pressure and number of cycles, decreased with the concentration of chitosan, while both the concentration of acetic acid or sodium acetate and temperature had a negligible influence. What\'s more, theoretical model was built and the mechanism of homogenizer was discussed.

2采用高压均质-H_2O_2联合降解壳聚糖，其降解效果随H_2O_2溶液浓度的增大而提高，随壳聚糖溶液浓度的增大而降低，随HAc溶液浓度的增大先升高后降低，随均质压力和温度的升高而提高，随循环次数的增加而提高。

Homogeneous pressure and the number of passes through the homogenizer affect the entrapment efficiency and average particle size in different degrees.

以乳脂肪球膜磷脂为膜材，采用高压均质法制备免疫球蛋白G脂质体，研究了不同磷脂浓度、不同均质压力和不同均质次数对脂质体的包埋率和平均粒径的影响。

The effect of hemi-cellulose content on fiber horrification and paper performance in recycling is studied concerning soda-AQ reed pulp, SP reed pulp and KP soft wood pulp.

研究了烧碱蒽醌法苇浆、碱性亚钠法苇浆、KP法针叶木浆在回用过程中纤维保水值、纤维聚戊糖含量以及成纸性能的变化，结果表明纸浆在回用中打浆前后聚戊糖含量稍有下降，而保水值增加；随着回用次数的增加，聚戊糖含量变化不大，但保水值却大幅度下降；成纸性能在回用中逐渐下降，而光学性能则向良好的方向发展。

The residual gas pressure in an electron tube can be measured when the tube itself is operated as a hot cathode ionization gauge.Usually,its sensitivity K is determined by the method of gauge calibration.In this paper,author try to determine the sensitivity K by ca- lculation.The formulae for this purpose have be found out,and are used for both plate and cylindrical electrode systems.

把电子管接成热阴极电离计的工作形式，用来测量管内残气压强时，其灵敏度如何计算的问题在本文中作了讨论，给出了平板形电极系统和圆柱形电极系统的灵敏度解析式，对式中各量的计算作了详细介绍；并指出四极管中电子在电离区的平均渡越次数的表示式与三极管中的完全不同。

Use biochemical method to observe the effect of electro-acupuncture on AchE、SOD、MAO、NO、NOS of senile dementia AD rat's brain tissue; use immunohistochemistry technique to observe protein kinase expression of hippocampal; use optical and electron microscope to observe morphosis change of rat's brain tissue; use in situ hybridism technique to observe aspartate receptor mRNA expression of hippocampal; use water and electric maze experiment to observe rat escape latent period and mistake times, to understand it's learning and memory ability.

分别用生化方法观察电针对AD大鼠脑组织胆碱酯酶、超氧化物歧化酶、单胺氧化酶、一氧化氮、一氧化氮合酶的影响；用免疫组化方法观察海马组织蛋白激酶的表达；用光、电镜方法观察大鼠脑组织形态结构的变化；用原位杂交方法观察海马组织天门冬氨酸受体rnRNA的表达；用水迷宫和电迷宫实验观察大鼠逃避潜伏期和错误次数，以了解其学习记忆能力。
