The largest chemical shifts were observed for the proton 1.48 ppm adjacent to the central pyridinium ring and para-protons 1.47 ppm with respect to the nitrogen of pyridinium.

对于与中心吡啶环相邻的质子（ΔHa=1.48ppm）以及相对于吡啶的氮的对位质子（（ΔHc=1.47ppm）观察到了最大的化学位移。

The polycondensation of the benzoguanamine and pyromellitic Dianhydride was carried out under microwave irradiation, and the resulted polyamic acid was grafted with TDI-para position substitution aniline derivatives. Thus graft polymers with different electronic effect of the end group in side chain were obtained.

将微波辐射合成的苯代三聚氰胺-均苯四酸二酐体系的PAA与TDI-对位取代苯胺衍生物反应，通过改变TDI－对位取代苯胺衍生物的对位取代基来合成具有不同电子效应的侧链端基的接枝聚合物。

In the process of extractive distillation o f butadiene,thequality of the byproduct butane-butene raffinate are rel ated to many process para meters, which are coupling and with noises.

丁二烯萃取精馏过程中，副产品抽余液的质量和很多工艺参数有关，工艺参数之间又是相互关联、耦合的，并具有噪声。

The raffinate column in the eluxyl unit of an aromatics complex is the key fractionator to separate C8 aromatics from para-diethyl benzene. PDEB is expensive and only if the PDEB content in C8 aromatics side cut is less than 25×10^(-6) mol/mol, the operation cost could be lowered effectively.

对二甲苯装置吸附分离单元的抽余液塔是分离碳八芳烃(C8A)和对二乙苯的关键精馏塔，PDEB价格昂贵，在侧线C8A中的含量要求小于25×10^(-6)mol/mol才能有效降低装置操作成本。

The results of batch experiments showed that the anaerobic biodegradation kinetics of 2-CNB and 4-CNB by granular sludge were follwed by first-order reaction. The nitro groups of 2-CNB and 4-CNB were more easily attacked by electron than chlorines and they were reductively biotransformed to amino groups under anaerobic conditions. The acclimated anaerobic granular sludge, which could dechlorinate 4-chloroanline to aniline, showed that it had the ability of para-dechlorinating. The anaerobic biodegradating on pathway of 2-CNB and 4-CNB were suggested as follows:AbstractIn ZVI(zero-valent iron, Fe0)-reduction system, the nitro groups of 2-CNB and 4-CNB were reductively transformed to amino groups.

2分批试验结果证明，颗粒污泥降解2-CNB和4-CNB遵循一级动力学，在厌氧条件下，CNB发生序列的硝基还原与脱氯作用，苯环上的硝基比氯原子更容易受到亲电子攻击，发生还原反应生成氨基；所获得的颗粒污泥具有对位脱氯活性，可使4-CA进一步脱氯形成苯胺。2-CNB和4-CNB厌氧降解的建议性途径为： ZVI(Zero-valentiron)对2-CNB和4-CNB的作用主要是将苯环上的硝基还原为氨基；在ZVI与污泥共还原转化体系中，ZVI对氯代硝基苯的硝基转化具有一定的促进作用，但因ZVI对中间产物的吸附特性，终产物形成速率趋慢。

Methods From July 1995 to April 2005, three operative methods, cartilage bracket and retroauricular expanded flap, silicone bracket and retroauricular flap and full-thickness skin grafting,local excision and para-position suture, were employed to treat 11 cases of traumatic partial auricle defects.
