母体

Coli lpdA mutant has the potential to produce pyruvic acid from xylose and mannose.

这些结果对构建以大肠杆菌为母体的模式"细胞工厂"有参考价值。

The role of the oxidant used was considered to be a quencher of the semiquinone radical anion of HA to its parent quinone to increase the relative concentration of HA so that the generation of SO~3^- via the electron transfer interaction between Hypocrellins and SO~3^2^- was accelerated.

氧化剂在这一反应中的作用为：将产生的竹红菌素半醌负离子自由基氧化至其母体醌，增加反应物的相对浓度，同时使竹红菌素与SO~3^2^-之间的电子转移循环进行，加速SO~3^-的产生。

The radiochemical separation procedure of 132Ⅰ was designed on the basis of half-lives of iodine and tellurium isotopes in mixed fission products.

依据混合裂变产物中碘及其母体啼的同位素的半衰期设计分离132Ⅰ的流程。

They're gonna reinsert my body.

我会重新接上母体

Diagnostic ultrasound in early pregnancy can make embryonate rats' SOD and MDA levels change ,but the changes can be reparable.

其总的趋势是随着孕期的延长MDA含量稳定于某一水平。结论孕早期接受一定剂量的超声辐照能够导致母体氧化-抗氧化状态的阶段失衡，但仍然具有可复性。

The study employed fenpropathrin to jeopardize pregnant rats modeling as the experimental object to observe and analyze the effective of fenpropathrin to the pregnant SD rat itself, the filial generation and the reproductive capability.

以甲氰菊酯染毒妊娠大鼠模型为实验对象，观察、分析甲氰菊酯对母体、妊娠及子代生长发育和生殖能力的影响，评估甲氰菊酯对免疫系统、神经系统及生殖系统的可能损害，并初步揭示其机理。

The Rydberg states of these amines arefirstly 2- or 3-photon resonantly excited, then the intermediate states are further excited toionization continuum.

一个明显的共同特点是母体离子由α-键断裂或拟-α键断裂产生的碎片离子强度很大。

In Chapter 5,the pyrolysis of substituted six-membered ring model compound 4-methyl pyridine has been investigated.Instead of detail theoretical analysis of the reaction mechanism,the general results have been proposed from the products distribution and the combination of the pyrolysis investigation of its analogous pyridine.The major products are H_2,C_2H_2,C_4H_2,C_3H_3N and HCN,here HCN is not a primary initial product at low extent of decomposition.The mole fraction profiles of products have been obtained from the near threshold ionization.The pyrolysis of 4-methyl pyridine is initiated from the methyl abstraction and hydrogen abstraction procedures which are associated with the understanding of the soot formation and the NOX precursor correspondingly.

主要产物为H_2，C_2H_2，C_4H_2，C_3H_3N和HCN，其中HCN为非低温时的热解产物；通过近阈值电离并导出物种随温度变化的摩尔分数曲线，更详细地定量地描述了产物随温度的变化。4-甲基吡啶热解主要从母体脱甲基和脱氢两个初始反应出发，一种趋势是形成大质量数的苯并或杂环的多环化合物，有助于了解炭黑形成过程中的复杂化学过程；另一趋势是开环生成小的碳氢和腈类物质，实验得出的含氮物质的种类及随温度变化有助于了解NO_x的前驱物质的形成及其变化规律。

Sometimes I think about those people s till plugged into the Matrix.

当我想到仍受母体控制的人们……。。

Cluster sampling: When the basic sampling unit in the population is to be found in groups or cluster s the sampling is sometimes carried out by selecting a sample of cluster s and observing all the members of each selected cluster .

整群抽样：一种抽样方法。当母体中的基本抽样单位是按群、组分类时，有时抽样方式是选择一类样本群组，然后对被选择的群组中的每一个样本单位的全体成员进行观察。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
