The characteristic of ABR is change water power characteristic and to improve the term of mass transfer in the reactor in order to increase the reaction velocity; and increase alkalinity to improve the capability of abirritation of the system through add Na2CO3 to reaction and a optimal pH condition which fit to acidic bacterium come into being. In result, the organic matters are removed efficiently in system.

异波折板水解酸化反应装置最大的特点是改变了水流特征，改善反应装置内酸化菌与基质之间的传质条件，以加快反应速率：同时在反应装置内加入碳酸钠，碳酸钠溶液作用在于提高反应装置内废水的碱度，增强系统的缓冲能力，把pH值控制在适合酸化菌生长的范围，充分发挥微生物的活性，使系统的有机去除能力大大提高。

The inhibitor for DNA methyltransferase, 5-azacytidine (5-azaC), can demethylate the methylated DNA and restore transcription of genes. High dose homocystine can mediat DNA methylation and suppress gene expression.

应用甲基转移酶抑制剂5-氮杂胞苷(5-azacytidine， 5-azaC)可以使甲基化的启动子去甲基化，启动基因重新转录；高浓度同型半胱氨酸(homocystine， Hcy)可以介导基因甲基化而抑制其表达。

CNTs were first pre-treated using acid solution (HNO3) to obtain CNTs functionalized with carboxylic groups. Subsequently, the stearyl alcohol was grafted onto CNT with the assistance of dehydrating agent, N,N'-dicyclohexyl-carbodiimide. Excellent dispersion in organic solvents such as acetone, THF, and chloroform was found for the modified CNTs (CNT-C18). In addition, the PBS/CNTs nanocomposites were then prepared through simple melt-blending. Mechanical properties, thermal behavior, conductivity of resultant polymer/CNT composites were investigated. The results show that excellent dispersion of nanotubes in the PBS matrices was achieved.

为了增加多壁奈米碳管在复合材料中的分散性，将碳管表面进行化学修饰，首先将多壁奈米碳管浸入HNO3溶液中，进行酸化，使碳管表面带有羧酸的官能基，然后再加入十八烷醇，在温和的条件下，藉由N，N'-二环己基碳二亚胺(N，N'-dicyclohexyl- carbodiimide，DCC)脱水剂脱水，使碳管和十八烷醇之间产生酯基的化学键结，改质后的碳管可以分散在acetone、THF、chloroform…等有机溶剂中，结果显示成功的利用DCC脱水剂完成碳管的改质。

Bezaldehyde was used as protective agent in first method.S-Epichloeohydrin was aminated and acidulated to give(2S)-1-Amino-3-chloro-propanol Salts.The acetylation of (2S)-1-Amino-3-chloro-propanol by acetic anhydride produced the intermediate-N-[2--3-chloropropyl]acetamide.And then at 20℃,in the presence of lithium tert-butoxide,benzyl 3-fluoro-4-morpholinophenyl carbamate react with-N-[2--3-chloropropyl]acetamide to give linezolid in total yield of 43.6%.
