Circuit breakers are the important equipments in the electric power system, which get out of order due to the inactivation in the aspect of insulation characteristic, mechanical characteristic and electric characteristic,the losses that they cause are a few thousands times more than price of themselves.

断路器是电力系统中的重要设备，在运行过程中可能发生的故障主要是机械故障与绝缘故障，由于它的故障所导致的损失可能为其本身价格的数千倍甚至数万倍，因此对断路器进行状态监测，及时了解断路器的运行状况，成为电力系统十分关注并迫切希望解决的问题之一。

Mitochondrial gene fragments of COⅠ and Cyt b of 24 species in the subfamily Pierinae and Coliadinae were amplified and sequenced. Combing these with the homologous sequences of 2 species from GenBank and using 2 species of the Satyridae as the outgroups, the molecular phylogenetic trees of these groups were reconstructed with neighbor-joining and bayesian inference methods.

测定了粉蝶科的粉蝶亚科和黄粉蝶亚科14属共24种线粒体COⅠ和Cyt b基因部分序列，并从GenBank中下载了2种粉蝶的同源序列，以眼蝶科的2个物种为外类群，运用NJ法、贝叶斯法分别重建了分子系统树，探讨了它们的系统发生关系。

The result was consistent with morphology of Pleuronectiformes on the whole.In the topology founded,Scophthalmus maximus and Solea senegalensis formed an independent branch each other and showed far relationship with species of Bothidae and Pleuronectidae,the phylogenic position of Solea senegalensis is accorded with the reported result of analysis made by mitochondrial genome.

运用PAUP软件对15种鲽形目鱼类与另外7种不同种属鱼类进行了分子系统进化树分析，结果与根据传统的形态学和生化特征分类进化地位基本一致，在15种鲽形目鱼类中只有大菱鲆和塞内加尔鳎各自单独形成一个分支且与鲆科和鲽科鱼类相距较远，其中塞内加尔鳎等种类的分类地位与根据线粒体DNA序列分析的系统发生模式基本吻合。

Political development theory is an important field of modern behaviorism politics research,and concerns the translation process form the unadvanced political systems to advanced systems.

政治发展作为现代政治学的一个重要研究领域，主要研究不发达政治系统向发达政治系统变迁的过程，一般是指传统社会向现代化社会转化中政治领域发生的变化。

We call for a reform of the international monetary and financial system to enhance its stability and eliminate global economic disproportions (or to reduce the risk of their emergence).

我们提倡一场针对全球货币金融系统的革新，从而增强该系统的稳定性，消除全球经济比例失调现象（或降低该现象发生的危险系数）。

The author has made researches on the social occurrence of man's functions of symbols and finds out that the occurrence of babies' self-consciousness is achieved under the conditions babies have possessed dualistic attention-----that is to say, attention can concentrate on two signal sources at the same time or it has two focus of attention.

论文摘要本文作者对人的符号功能的社会系统发生进行了研究，发现婴儿自我意识的发生是在婴儿已经具有二元注意--即注意力能同时集中到两个信号源或者说有两个集中点--的条件下实现的，这种并行性注意使一种称为反身性条件反射建立成为可能，并形成了具有符号功能的神经机能组织--二联体。

For a kind of nonlinear dynamic absorber of blade out of plane, the combination resonance is studied in Chapter 6 by using the method of multiple scales. The approximate steady state solution of the first order is derived first Then, the stability and bifurcation properties of the system response are investigated.

我们针对一种桨叶挥舞方向的非线性动力吸振摆，利用多尺度法考察了它发生组合共振的情形，给出了系统响应的一阶近似稳态解，并且详细分析了系统响应的稳定性和分叉特性。

Research on water hammer with gas in pressure conduit system Through physical experiments, researches on pressure conduit system with gas releasing and liquid column separating, which consist of observing flow patterns, testing the conditions under which liquid column separation brings into existence and the water hammer in water interception collision, and studying effects resulting from gas content and different water velocities in pipeline, was done.

输水管道系统中含气水锤研究通过物理试验，对有压输水管道系统中的气体释放与液柱分离进行了研究，观察其流态、测试液柱分离发生的条件及断流弥合水锤压力，研究了含气量、流速等参数对液柱分离的影响。

It brief narrates the achievement and operation effect of the technique annd equipment of speed control system in hump of marshalling yard , and put forward the problem of take place in operation, and bring forward some assuming to ensure the function stabilization and reliability of speed control system.

本文简述我国驼峰调车场的调速技术和调速设备取得的成就和运营效果，以及系统在运营中发生的问题，并在保证调速系统功能稳定可靠性上提出一些设想。

Tobacco tomato spotted wilt disease was found in many provinces.This disease is widely distributed in Yunnan production tobacco area and it causes above 60% losses in some area. The tomato spotted wilt disease is one of the most potentially dangerous disease of tabacco in the world. This paper reviewed the distribution,symptomology, causal agents, pathogenic mechanism, the composition and function of virus genome and epidemiology and management of the tobacco tomato spotted wilt disease.

目前该病在中国许多省均有发生的报道，在云南烟区广泛分布，在局部地区可造成60%以上的严重损失，烟草番茄斑萎病被认为是世界上对烟草最具潜在危险病害之一，较为系统全面的综述了烟草番茄斑萎病的发生与分布，病害症状学，病原物，致病机制，病毒基因组结构和功能以及病害的流行及控制等方面的研究进展。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.
