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。

It also is not reported about what influence in the process of cell polarity and chemotaxis in neutrophils by block SOCE.

但SOCE机制是否参与中性粒细胞极性化过程以及在此过程中起何种作用，阻断SOCE后对中性粒细胞极性化过程以及趋化性有何影响，尚无确切报道。

After acetylating, the effect of the transformed PAF on platelet aggregation was compared with that induced by standard PAF for quantification.

The emotions and the mentalities of the figures have convergence, too.

《雷雨》和《秋叶》的人物关系具有很强的同构性，人物的情感和心理也有着明显的趋同性。

The plum-apricot germplasm resources were analyzed by RAPD markers. The results showed that plum-apricot was more close to the related species with low polymorphism. The clustering results were indicated that most plum-apricots were more close to Chinese plum with the similarity of morphological description, thus the female parent for plum-apricot was probably plum in the occurrence naturally. The result of S allele-specific PCR amplification showed that plum-apricot had only one band with the similarity with plum, thus evolution similarity of plum-apricot was more close to plum than apricot.

5对参试杏梅种质资源的RAPD分析表明，杏梅与其近缘种之间亲缘关系较近，多态性相对较少；聚类分析结果显示大部分的杏梅与中国李的遗传距离较近，与形态学上的描述基本一致，因此杏梅种质资源在自然界中产生时，其母本可能为李；同时S等位基因的扩增结果显示杏梅与李的扩增条数一致，都为一条，因此推断杏梅与李的进化趋同性可能较杏更近。

Moreover, MCTs are rapidly hydrolysed and oxidised to fatty acids and ketones which can be readily utilized and storage is very limited.

一些体外的实验显示LCT会使白血球的趋化和移动性受损而降低白血球的活性，也会抑制免疫球蛋白的合成和吞噬细胞肿瘤坏死因子之产生。

Titres of neutralization antibody induced by DNA immunization were correlated to efficacy of protective immunity.

目的探讨细胞因子及趋化性细胞因子在结核患者保护性免疫中的作用。

In histopathology sections showed that alveoli were complete and clear with walls being thin and brittle. In experimental group, some petechia were observed in lung samples , the area of fibroblast and fibrinogen in histopathology sections were found , and the ground-glass predominance and reticulation structure in Micro-CT findings were increased during the period from the 1st week to the 3rd week, and degrade in the 4th week after the administration.

结果显示，控制组之肺脏检体色泽正常，没有出血，组织病理学则以I型肺泡细胞为主，无间质性肺炎且肺泡完整清净，肺泡壁薄而完整；实验组方面，第一~三周肺脏检体外观及组织病理的呈现出血点及出血病灶且越趋严重，第四周则消退，且Micro- CT影像评估亦相同。

Secondly,due to the gradual loss of central authority,the regional warlords arbitrarily wlthholded stamp taxes,printed revenue stamps privately and illegally, overissued and over-mortgaged revenue stamps.This phenomenon made the tax system severely damaged and ultimately attributable to the unsystematic.Thirdly,the stamp tax system increasingly chaotic made the production and livelihood of the people inconvenient.

三是印花税制的趋乱性发展，给商民的生产生活带来了极大的不便，无论是税款征收还是税务稽查，甚为社会各界所厌恶，各地商民纷纷起而反对，尤其是在各地商会的领导下，那种有组织的抵制行动对政府的制衡作用使得国家权力在内重外轻及政权不稳的情况下汲取社会资源更加不易，突出反映了民间社会力量的日渐强大。
