This article reviews three kinds of methods for manufacture halogenated aromatic amine ,and the strong and weak points of the three reduction methods are pointed out.

本文综述了由卤代芳硝基物还原制备卤代芳胺的三种方法，并对几种还原方法的优缺点进行了对比和讨论，得出水合肼还原具有很好的应用前景。

Not only can the method be used to predict haloenated propance,but can help to understand the quantitative relation between boiling point and molecular structure of halogenated propanes as well.

本文方法的提出，不仅在一定程度上揭示了卤代丙烷沸点与分子结构之间的定量关系，而且为工程上提供了一种预测卤代丙烷沸点的有效方法。

The conversion of alcohols to alkyl halides was investigated using acidic ionic liquid X as halogenating agent, acidic catalyst as well as medium.

2以酸性离子液体X兼作卤代试剂、反应介质和酸性催化剂，研究了醇转化为卤代烃的反应。

The conversion of alcohols to alkyl halides was investigated using acidic ionic liquid X as halogenating agent, acidic catalyst as well as medium. The reactions of primary alcohols gave very satisfactory conversions and selectivities except for the substrates with lower boiling point,such as n-octanol and benzyl alcohol. They obtained the corresponding halides with almost quantitative yields(95%-100%).The secondary alcohols also gave the corresponding halides with excellent conversions, however, the by-products of dehydration were detected.

伯醇除某些低沸点底物外，都以高转化率(最高达100％)和高选择性(最高达100％)转化为相应的氯代烃、溴代烃和碘代烃，例如正辛醇、苯甲醇，在X中进行卤代反应得到令人满意的结果，无论氯代、溴代还是碘代得到卤代产物的收率一般都很好华东师范大学化学系01级博士学位论文(95十100%)，极少有重排产物及脱水产物被检测出来。

Marinades don't just make food taste good. Studies show using a marinade helps blunt the heat so fewer HCAs are formed.

卤汁不仅使烤出来的食物更可口，而且有研究表明使用卤汁有助降低食物的温度，这样能减少产生异环胺。

The size of the eggs and nauplii of Xiechi strain was significantly smaller than the parthenogenetic strain.

本文观测了一种新近发现的卤虫品系——山西解池硫酸盐湖卤虫品系。

The nauplii were sampled after fed with NFLX at different does and different time, the concentrations of NFLX were determined by High Performance Liquid Chromatography.

将卤虫无节幼体分别放入0.5、1、1.5、2.0g/L的NFLX混悬液中强化，不同时间点取样，高效液相色谱法测定卤虫体内NFLX含量。

The values of EAAI in rotifer and nauplii of Artemia were all above 90 for different larval stages of Scylla serrata. It was suggested that rotifer and nauplii of Artemia may satisfy the nutritive requirement of larval Scylla serrata for amino acids in diet protein.

对于各期幼体，饵料轮虫和卤虫无节幼体的必需氨基酸指数均大于90，可以认为，轮虫和卤虫无节幼体能够满足锯缘青蟹幼体对饵料中必需氨基酸的营养需求。

By reaction of alkyl halide with metallic sodium or hydrogen acid to restore the alkyl halide obtained.

可由卤代烷与金属钠反应或以氢碘酸还原卤代烷制得。

The main reasons were that the algae and organism in the water decreased the ability of removing pollutants by coagulations, the algae which grown again in the open sedimentation tank weakened the removal effect of algae by coagulation; because of the accumulation of algae and algae toxin in the filtration tank, the concentration of algae toxin in the effluent increased; by the function of fluid chlorine, the algae and organisms after the filtration will release microalgae toxin and produce a lot of byproduct such as microalgae toxin, sobomyl and so on, meanwhile, the chlorination produce considerable halide and halo-acetic acid and other disinfection byproduct.

主要表现在藻类和溶解性有机物的存在降低了混凝去除污染物的能力；藻类在露天平流沉淀池中再生长，抵消了混凝除藻效果；藻类和藻毒素在滤池中积累，导致滤后藻毒素升高；穿透滤池的藻类和有机物在液氯作用下，释放微囊藻毒素、土臭素和二甲基异冰片等胞内物质，同时生成数量可观的卤代烃和卤乙酸等消毒副产物。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.
