In the current study, anoxic dechlorinations of p, p'-DDT,γ-HCH, HCB in the Liao River sediment were studied under the following conditions: without any additional short chain carbon substrates or vitamin B〓; with the addition of short chain carbon sources (including sodium lactate, sodium propionate or sodium acetate); with the addition of vitamin B〓; with the addition of both short chain carbon substrates and vitamin B〓, with the addition of sodium dodecyl sulfate , a kind of surfactant; the coexistence of the three chlorinated compounds.

氯代有机物一般都是典型的持久性环境污染物，其中部分氯代有机物还是环境激素类物质，例如，滴滴涕、林丹和六氯苯等，这些氯代有机物在环境中的迁移转化一直是国际环境化学领域的热点、重点课题。氯代有机物进入环境水体后，成为沉积物吸附态有机污染物的重要成分，天然水沉积物经常处于缺氧状态。因此，研究氯代有机物在天然水体沉积物中的缺氧脱氯行为是非常必要的。

In the current study, anoxic dechlorinations of p, p'-DDT,γ-HCH, HCB in the Liao River sediment were studied under the following conditions: without any additional short chain carbon substrates or vitamin B〓; with the addition of short chain carbon sources (including sodium lactate, sodium propionate or sodium acetate); with the addition of vitamin B〓; with the addition of both short chain carbon substrates and vitamin B〓, with the addition of sodium dodecyl sulfate , a kind of surfactant; the coexistence of the three chlorinated compounds.

本文分别采用不外加碳源和维生素B〓外加碳源（包括乳酸钠、丙酸钠或乙酸钠）、外加维生素B〓以及同时外加碳源和维生素B〓的方法，考察了p，p'-DDT、γ-HCH和HCB三种氯代有机污染物单独或混合存在下，在辽河沉积物中缺氧脱氯降解的情况，主要得到以下结论

The method is just like the QuikChange site-directed mutagenesis method except for its special primer. This pair of primers is composed of a long primer and a short primer which is central overlapped.Both of the Tm of 5\'sequence in long primer and Tm of 3\'sequence in short primer are above 66℃.The Tm of short primer is almost half of that of long primer.It is convenient to perform insertion or substitution mutation of DNA fragments larger than 20bp,In addition,it is highly applicable in research about the deletion mutation of DNA fragments larger than 2000bp.

我们实验室一直在寻找一种简单高效的可以用于基因的删除、插入及替代突变的方法，通过大量研究和实验发现，可以使用一种基于反向PCR原理，使用全新的引物设计的突变方法——&COP&突变法，该方法采用与QuikChange点突变法相同的操作步骤，其策略是设计一对中心重合的引物，长引物的5\'端序列和3\'端序列的Tm值均不低于66℃，短引物Tm值约为长引物一半，且与长引物中心重合互补。

DC power transmission simulationmodel is set up in this paper with the Matlab software, and various faults such as single-phasegrounding short circuit, phase to phase short circuit, three-phase circuit grounding shortcircuit and inverter bridge short circuit are simulated in this model.

用MATLAB软件建立了电力系统直流输电仿真模型，模拟了单相接地短路故障、相间短路故障、换流器桥臂以及单桥故障，经过近百次仿真运行，得出了各种故障下的特性曲线，准确描述了直流输电系统在发生大扰动后的暂态过程，并从理论上进行了科学分析，得出了各种故障对换相失败的影响。

Short of 商缺 Now it was a minute short of quarter to ten, and I edged my way toward the roo.

现在9点45还差一分钟，我慢慢的向房间走去。

This also means that China's coal prices in the short term, still be a high coal imports will slow pace of short-term.

这也意味着中国的煤炭价格在短期内依然将处于高位，煤炭进口步伐短期内不会放缓。

Especial, forv=36 and 76, the methods to construct D_(3×4)K_(36 and D_(3×4)K_(76 are differentfrom the methods used above. The above small designs are constructed byusing complete orbit and abelian group while the D_(3×4)K_(36 is constructed byusing short orbit and the D_(3×4)K_(76 is constructed by using short orbit andnonabelian group.

特别对于υ=36和υ=76这两个值，我们构造时用到的方法与我们前面构造小设计时用到的方法不同，前面我们构造小的设计时，都是基于完整的轨道和Abelian群的，但对于这两个值我们是用短轨道和非Abelian群进行构造。

The application of PDT to the inpatients of GBS with respiratory muscle paralysis has advantage such as simple operation, short ventilating time and short hospitalization duration, low occurrence rate of ventilator related pneumonia, etc. It should be considered as the first- choice method to opening the air-way for the disease.

PDT用于急性GBS综合征致呼吸肌麻痹患者具有操作简单、通气时间、住院时间短、住院期间呼吸机相关性肺炎的发生率低等优点，应作为该病开放呼吸道的首选方法。
