It indicates that the PANI particles constituted films are ball like or ellipsoid like; the film takes on tertiary structure; HClO4 servers as both an acid medium and a dopant; the crystallizability of the film seems poor; the relationship between film thickness and acid concentration is not in linearity; the conductivity of the film is on a level with semiconductor, whose value depend more on film appearance than acidity of acid medium; the film starts dedoping at 67.3℃ and end at 277.2℃.

结果表明，构成薄膜的聚苯胺粒子呈球型或椭球型；薄膜具有三级结构特征；高氯酸不仅作为介质酸，同时作为掺杂剂；薄膜的结晶性能不佳；薄膜厚度与介质酸的浓度并非线性关系；薄膜的电导率处于半导体水平；电导率大小与无机介质酸的酸性强弱有一定关系，与表面形貌关系更为紧密；高氯酸掺杂聚苯胺薄膜在67.3℃时开始脱掺杂，在277.2℃脱除完全。

We can get chitin and protein from the mycelium using the waste alkali and waste hydrochloric acid, so as to enhance its comprehensive benefits.7 The project of the comprehensive treatment of the mother liquorFor the reason of recrystallization, a large amount of mother liquor were produced with the production of IA, except for IA, it also contain residua sugar, mineral and colloid, which could prevent the recovery of IA crystal.

利用回收的树脂再生酸、碱从菌丝体中分离出甲壳素和菌体蛋白，提高的菌体的综合效益。7、衣康酸提取母液的综合治理方案由于衣康酸的提取采用的是重结晶法，因此，生产过程中会产生大量的母液，母液中除了含有衣康酸外，还含有残糖、无机离子及少量小分子胶质物质等，这些成分的浓度相对较高，抑制了母液中衣康酸的结晶和提取，导致这部分母液只能排放，不仅使衣康酸的提取率降低，也加重了污水处理的负荷。

Aminobutyric acid in tea was extracted, isolated and determined. Water achieve a better effect than ethanol in extracting γ-aminobutyric acid, and γ-aminobutyric acid content was enhanced by 20%; 732 positive ion resin columns (2.5×50cm) was used to isolate, citric acid and ammonia water were used as elutes, based on pH linear gradient. Results indicated that γ-aminobutyric acid inelute could reach 39%; thin layer scanner could measure the content of γ-aminobutyric acid.

对茶叶中γ-氨基丁酸的提取、分离及检测方法进行了研究，分别采用水和乙醇作为提取溶剂，结果发现用水提取能达到更好的效果，γ-氨基丁酸含量提高20％；同时采用离子交换树脂对γ-氨基丁酸提取液进行分离，提取液上732阳离子树脂柱(2.5 ×50cm)，使用柠檬酸和氨水缓冲液进行pH线性梯度洗脱，洗脱液中γ-氨基丁酸最高浓度达39％；采用薄层扫描仪对γ-氨基丁酸的含量进行检测，研究并确定了检测的条件及参数。

The mechanism of dioxygen oxidation of NTS to DNS in alkali solution under mild condition was inquired into. The result showed that the key step in the preparation of DNS from NTS was the formation of 4-nitro-2-sulfobenzyl anion as a result ionization of NTS in strong alkali and then oxidization to 4-nitro-2sulfobenzyl radical by activated dioxygen.

探讨了在温和条件下于碱的水溶液中氧气液相氧化4-硝基甲苯-2-磺酸制取4，4'-二硝基二苯乙烯-2，2'-二磺酸的反应机理，发现4-硝基甲苯-2-磺酸在碱作用下发生离子化生成4-硝基-2-磺酸基苄基阴离子，然后被活化的分子氧氧化成4-硝基-2-磺酸基苄基自由基是反应的关键步骤。
