With primers designed according to sequence(AY052417) of diapause pupae of oriental tobacco budworm registered on GenBank, a double-strand cDNA fragment of DH gene was obtained from RT-PCR amplification and was further cloned into pGEM-T Easy vector.

根据GenBank发表序列(AY052417)设计引物，以烟夜蛾(Helicoverpa assulta Guenée)滞育蛹为材料，利用RT-PCR技术扩增到滞育激素(diapause hormone，DH)cDNA，并通过TA克隆的方法将其克隆至pGEM-T Easy载体上，对目的基因进行测序，并利用设计的酶切位点将目的基因从T载体上切下。

The Class Cephalopoda is relatively indenpend in the Phylum Mollusca phylogeneticically,whose anatomic and behavioral characteristics are also unique.

This issue, based on the concepts of value rationality and instrumental rationality initiaed by Max Weber, analyzes the essentials of m odern society culture with references of the earliest fruits of the New Institut ional School. The author claims that the west culture, as the representation of modern society culture, does not necessarily disserve two sorts of rationality, while the hiding of generalized value rationality and the showing of the instrum ental rationality are combined to be the right esse...

从 马克斯·韦伯提出的价值合理性和目的工具合理性概念出发，结合制度经济学派研究的最新成果，分析了现代社会文化的实质，认为现代以西方为代表的文化并不具有割裂两种合理性的特质，相反普适性价值合理性隐藏与目的工具合理性的张扬的特殊统一方式构成现代社会文化的必然，所谓现代性危机是对此种隐藏的遗忘，并进而指出中国现代化进程中的真正文化危机是本土化的普适性价值合理性的缺位。

But the change that in recent years global virus is written and the purpose of fabricant had essential sex, had changed direction to be main purpose in order to get a benefit.

但近年来全球病毒编写和制作者的目的有了根本性的改变，已经转向以获取利益为主要目的。

Its purpose is to parse a project's CVS log, build a graph for each file representing branches layout, merge them all together and then creates a visual representation of the project.

它的目的是分析一个项目的CVS日志，为每个文件建造一个图像以表示分支布局，将它们所有都合并在一起，然后再创建一个可视化的项目表示。

The TCR firing angle can be fully changed within one cycle of the fundamental frequency, thus providing smooth and fast control of reactive power supply to the system.

即不管负载的无功功率如何变化，总要使二者之和为常数，这个常数等于电容器组发出的容性无功功率的数值，使取自电网的无功功率为常数或为0，即：=常数（或0），最终使得电网的功率因数保持在设定值，电压几乎不波动，从而达到无功补偿的目的，以抑制负载波动所造成的系统电压波动和闪变。

Of or belonging to the order Homoptera, which includes the cicadas, aphids, and scale insects, characterized by sucking mouthparts.

同翅目的属于同翅目的，其中包括以吸口器为特点的蝉，蜂虫和介壳虫

So to analyze in the aspect of description, it is useful to delouse the fount how inarticulateness comes into being; Based on the economic relationship and from the viewpoint of the pursuit of aim, the object of studying, the original creation of aesthetics, as well as the articulate knowledge and inarticulate knowledge, Polanyi distinguished the acquisitive way of science and technology. The development model of personal Knowledge can be generalized as the enthusiasm of seeking knowledge; Polanyi revealed how personal factors of mathematician cut across logical chasm, and gained mathematics findings in math" s activities. Thus he proved mathematics was also activity-needed techniques as natural science; Last evaluating the theory of "Personal Knowledge systematically, it can reveal its realistic significance and limitation.

波兰尼把认知结构区分为可言传知识与不可言传知识，与20世纪以来西方哲学的中心课题转向语言学的研究一致，所以从言述的角度出发，有助于了解不可言传性如何形成的根源；波兰尼以经济关系为立足点，从科学与技术的目的追求、研究对象、美的原创性，以及从可言传知识与默会知识的角度对两者的获取途径做了区分；其个人知识发展模式可以概括为：求知热情→启发性热情→说服性热情……；波兰尼揭示出数学家的个人因素是如何在数学活动中跨越逻辑鸿沟，取得数学发现的，从而证明数学同自然科学一样，也是一项需要技能的活动；最后对"个人知识"理论作一系统的评价，揭示"个人知识"理论的现实意义和局限性。

It mainly displays and turns the abstract quantitative relation into the appropriate geometric figure , find connection that exist under quantity from ocular characteristic of figure, so as to take , embarrass easy abbreviating , it melts latently to be an apparent purpose, make the problem be solved simple and directly .

它主要表现在把抽象的数量关系，转化为适当的几何图形，从图形的直观特征发现数量之间存在的联系，以达到化难为易、化繁为简、化隐为显的目的，使问题简捷地得以解决。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
