查询词典 degenerate distribution

The results show that the primers S37 and S61 are of apparently specific to the amplified bands of six strains, which establishes the basic for the degenerate molacular marker of Cordyceps militeris and confirms heterokaryosis and parasexuality of Cordyceps militeris.

结果表明，引物S37、S61对6个菌株的扩增谱带具有非常明显的特异性，该结果为蛹虫草退化分子标记奠定基础，并且在一定程度上也印证了蛹虫草异核现象和准性生殖理论。

Of course, in high summer temperatures, tea placed a long time will be granted rancid degenerate.

当然，在温度较高的夏天，茶汤的放置时间长了会发馊变质。

An efficient and rapidly method for strains screening was evaluated in this paper. New degenerate PCR primers were designed based on the homology of type n KS gene. PCR was used to screen the strains which include type Ⅱ ketoacyl synthase.

根据酮基合酶编码基因(ketoacyl synthase， KS)的同源性设计简并引物，并利用PCR技术快速筛选携带聚酮类化合物编码基因的放线菌菌株。

In the second case, popularized by Hoppe [12], the two endpoints of an edge are contracted to a single point and the triangles that degenerate in the process are removed.

第二个是由Hoppe提出的边的两个端点合并成一个顶点，而退化三角形移除掉。

If that husband and wife don't cultivate DaoDe and improve their morals, their family will easily transform to the one like icehouse, battle and sauna under the influence of the external cause---increasingly degenerate social morality. At last, that family will disaggregate.

特别是对因为是恶缘、报缘本因而组成的家庭，对那些不能修养道德，不继续提升夫慈妇贤品质，纯以经济利益构建关系的家庭，在社会道德滑坡不止的外因作用下，也就必然容易蜕变成冰窖式、战场式、桑纳式的家庭，最终难以避免解体的厄运。

The overwhelming majority of soil physical, chemical and biological quality indicators increased incipiently and decreased subsequently with the increasing of dam land and terrace use years. They have been degenerate state and degradation will be lasted.

坝地和梯田绝大多数土壤物理、化学和生物学质量指标随着经营时间的延续均经历了先逐渐升高后缓慢降低的演变过程，现已处于衰退并将持续衰退的状态。

A thicker active layer will absorb more incidents light, but too thick active layer will result in increasing in both series resistance and dark current, which will degenerate the performance of the device.

元件中不同的主动层厚度会有不同的光吸收量，较厚虽然可增加光吸收量，但相对地串联电阻、暗电流等特性皆会因厚度增加而增加，上述几点都会影响太阳电池的转换效率。

This causes the technology process to degenerate into political infighting, forces foul compromises, and creates delays.

这使得技术过程退化成了立场混战，导致了违反规则的妥协，延迟了规范的发布。

In our study,two important lepidopteron pests,beet armyworm and cotton bollworm were surveyed for their endogenous piggyBac.As a result,endogenous piggyBac elements were found in these two insects,and one of the piggyBac elements isolated from the genome of cotton bollworm was intact and thought to be potentially active.1 Clonging and sequence analysis of piggyBac from beet armywormUsing PCR technique,with degenerate primers,a DNA fragment of piggyBac-like element was cloned from the genome of beet armyworm,spodoptera exigua hubner.The DNA fragment was 456bp in length,and the deduced amino acid sequence shares 50%- 78% similarity with other piggyBac elements from insects.But one stop code was found in this DNA fragment.

由于转座子很难用常规的RT-PCR和RACE技术进行克隆鉴定，故本研究在兼并引物PCR的基础上，利用inverse PCR和vectorret PCR技术，不仅调查了鳞翅目两种重要的农业害虫甜菜夜蛾和棉铃虫的內源piggyBac存在情况，同时克隆到了內源性的piggyBac转座子，并且从棉铃虫中获得了一个结构完整、具有潜在活性的piggyBac转座子HaPLE1.1甜菜夜蛾piggyBac转座子基因的克隆与序列分析采用PCR技术，利用兼并引物，从甜菜夜蛾基因组中克隆出一个內源性piggyBac类似因子的DNA片段，并命名为SePLE。

In a word, there is no denying the fact that Commercialism and Mammonism erode all spiritual values, and degenerate the cultural fabrics of a society.

一句话，如今存在一个不可否认的事实，那就是商业社会和拜金主义腐蚀了所有的精神上的价值观念，同时退化了一个社会的文化结构。

A carrier gas such as nitrogen is directed through line 20 and valve 22 to connect with line 26 and mix with the gas sample.

如氮气之类的载体通过管线20和阀22引入，与管线26相通，与气体样品混合。

But for the most part, knaves and parasites had the command of his fortune

然而支配他的家产的大多是恶棍和寄生虫。
