In order to provide theoretical basis for applications of plasma method in degradation of pollutants,the degradation mechanism of halons(CF 2ClBr,CF 3Br)with cold plasma technology was studied.In oxygen free systems,the amounts of some products change dramatically with the discharge time.When enough oxygen is present,the dominant product is CF 2O.

利用低温等离子体技术对哈隆类物质 CF2 Cl Br和 CF3Br进行了降解反应研究，发现无氧条件下某些降解产物的量随放电时间不同而出现波动，表明降解过程中存在竞争反应；而氧气过量条件下不存在竞争反应，其主要产物为 CF2 O等。

It can be deduced that the similar P450 gene responsible for pyrethroid resistance is also existed in houseflies in Beijing district.But the same gene in the two districts have some differences in their P450 gene structure.

Hinf I酶切发现扩增产物上并没有相应的酶切位点，说明扩增产物与原序列MDCYP6D1的相应部分不一样，提示这一用PCR方法在北京地区的家蝇中扩增出的P450基因片段有可能对应一新的P450基因。

文章概述了芳香酮取代基的电子效应与空间效应、手性催化剂和手性试剂的结构、反应体系等对产物光学活性的影响，以及全细胞酶、分离酶等不同生物催化体系中芳香酮结构对产物光学活性的影响，并展望了不对称还原的研究及应用前景。

According to structure analysis, the contents of α-helix and dimer structure in refolded eMDH were increased by the cooperation, and eMDH activity was enhanced.

对复性产物结构的初步分析发现，耦合作用可使eMDH分子的α-螺旋及二聚体含量明显增多，因此复性产物的活性也显著提高。

As for the direct reactions of ketones or aldehydes and DyI_2, the formation of products can be controlled by adjusting the quantity of DyI_2, when DyI_2 is used as 1 equiv.

对于醛、酮直接与DyI_2的反应，则可以通过调节DyI_2的计量来控制产物的生成，当DyI_2的用量和醛或酮是等当量时，得到的是频那醇偶联产物；而当DyI_2的用量是两倍当量时，得到的就是相应的醇。

Thermodynamics analysis for the reaction system showed that high-temperature was favorable to produce ethylene, but byproduct diethyl ether yield increased under low-temperature.

对乙醇脱水的热力学分析表明，高温有利于目的产物乙烯的生成，低温有利于副产物乙醚的生成。

The effects of the major and minor factors on the current efficiencies of the main products: 2,5-dimethyoxy-2,5-dihydrofuran, at the anode and butyl alcohol at the cathode, respectively, varied.

影响阳极主要产物2，5- dimethyoxy- 2，5-dihydrofuran，及阴极主要产物丁醇之电流密度的主要及次要原因是不同的。

The results show that the zinc coating is eroded mostly, and some red rust and black rust appear on the substrate in the environment of oxygen supplied intermittently.

结果表明：在间歇通O2的情况下，锌层大部分被腐蚀，而且在基体上有一些红锈和黑锈产生，镀锌板表面的腐蚀产物呈现着不均匀的针状物；而在间歇通N2时，镀锌板的锌层脱落面积较少，基体上没有产生红锈，腐蚀产物呈大块状；在间歇通O2和通N2的情况下，镀锌板的腐蚀速率先增后降，在200 h时，前者的腐蚀质量损失速率是后者的2倍左右；镀锌板附着库尔勒泥浆时的腐蚀过程受氧去极化过程控制。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
