查询词典 degenerate

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。

However, only one of these megaspores is functional; the three nearest the micropyle soon degenerate.

然而，这些 megaspores 的只有一个是功能的；那三最接近 micropyle 很快退化。

At present, our main result in this direction is that we have proved the topological charge of instantons in degenerate noncommutative spacetime to be an integer, i.e., to be exactly its instanton number, using ADHM construction; by the way, we have discussed the realization of conformal symmetry of the ordinaty instanton solutions on the instanton moduli space and obtained some primary result, again using ADHM construction.

目前该方面所取得的主要成果是利用ADHM构造证明了退化的非对易时空中瞬子的拓扑荷为整数，即严格等于其瞬子数；另外，顺带用ADHM构造对通常规范场论中瞬子解的共形对称性在参数空间上的实现进行了研究并取得了初步的成果。

At the same time, it is inorganic and therefore not subject to erosion fungi, non-perishable, non-degenerate, can not easily be moth-eaten rat-bite, it does not contain asbestos, therefore, vermiculite is the natural green flame retardant, heat insulation, fireproofing materials.

同时，其为无机物，故不受菌类侵蚀、不腐烂、不变质、不易被虫蛀鼠咬，也不含石棉，因此，蛭石是天然的绿色环保阻燃、隔热、防火材料。

Moreover the result is straightforwardly generalized to the case of multipartite non-degenerate mixed states.

进一步，三体的结果经过推广可以应用于多体任意维非简并的量子混合态。

Lu Xun once pointed out that the way out for Naras was degenerate or repentant.

鲁迅曾指出：娜拉们的出路：不是堕落，就是回来。

Tracing the development process (i.e. the life history) of vacuum cleaner, we found similarities between product development and evolution trend, such as the theory of "evolve by use and degenerate by no-use" by Lamarck, the theories of mutation, excessive breeding, competition for existence, and survival of the fittest in the Theory of Natural Selection by Darwin and Wallace, as well as the theory of mutation in Neo-Darwinism.

文中经由观察吸尘器诞生后的发展过程，亦即它所经历的生命史中，归纳出它所显现的演变现象有些似乎和演化论有相似之处，例如：Lamarck的用进废退演化现象，Darwin天择说中的变异、过度繁殖、生存竞争、适者生存等，及集合各家说法的Neo-Darwinism中的突变等。

I can not make it blossom and suits me

我不能让树为我开花

When temperatures are above approximately 80 °C discolouration of the raceways or rolling elements is a frequent feature.

当温度高于 80 °C 左右时，滚道或滚动元件褪色是很常见的特征。
