The results suggested that application of insecticide might be one important factor affecting the genetic structure of B. tabaci biotype B.

结果提示，化学农药的施用可能是B型烟粉虱群体遗传结构的重要影响因素之一。

The biotype, genetic structure and invasive mechanism of B. tabaci populations from different regions were investigated using several kinds of molecular markers.

本研究使用分子标记方法对采自国内外近30个地区的烟粉虱种群的生物型，遗传结构以及入侵分子机制等进行了深入的研究。

The high frequency of BLAD carrier farms indicated continuous selection of TL bull and semen for breeding DHI cows is important.

高频率的BLAD杂合型提醒DHI计画需持续宣导公牛与精液的筛选，总乳检测方法可以监控牛群遗传动态与降低检测成本。

A genetic test screened DNA mixes of tank milk from 72 DHI herds. Results showed 65 herds had at least one cow carrying BLAD(bovine leukocyte adhesion deficiency) defect gene but none of 72 herds had any DUMPS (deficiency of uridine monophosphate synthase syndrome) carriers found.

遗传检测72个参加DHI牧场的总乳混合DNA，发现有65 场中仍至少有一头母牛带有淋巴球黏力缺失症(bovine leukocyte adhesion deficiency， BLAD基因，但没有发现任何牧场有杂合型的单谱症(Deficiency of Uridine Monophosphate Synthase， DUMPS)泌乳牛。

One embryonic cell can be separated into many blastomere cells. As be the nuclear donor of the embryonic cell nuclear transfer, it can breed the number of eminent species largely, increase the number of endangered animals, supply large number of supply same genotype animals, improve the efficiency of gene transfer and sex control and offer same genotype apparatus or organ for human transplant.

一个早期胚胎细胞可以分离多个卵裂球，以此作为核供体进行胚胎细胞核移植，可以大量扩繁优良品种的数量，增加濒危动物的数量，为科学研究提供大量遗传同质的动物，提高转基因和性别控制技术的效率，提供基因型相同的器官或组织供人类移植。

Although samples 5, 10, and 17 present certain morphological character of the component of Caucasoid, the mtDNA haplogroups of them is still Asia-specific.

另外，该墓地的样本5和样本10以及样本17在形态特征上均表现出含有欧罗巴人种成份，但在母系遗传上表现为亚洲特异的单倍型类群。

Objective: To explore the risk factors in the genesis of cleft lip and palate patients.

目的：探讨非综合征型唇腭裂的可疑环境因素和遗传因素。

STR locidistribute extensively and have higher information, polymorphism, and its heredity is based on Mondel codominant inheritance. We usehalf-quantitative analysis of STR polymorphism loci, to set up a clinicalpractical method that is highly accurate in rapidly detecting and prenatalgene diagnosing Down syndrome.

STR广泛分布于人类基因组中，一般认为，人类基因组平均每6～10Kb就有一个STR基因座，STR有高度多态性并遵循孟德尔共显性遗传，具有操作简便、分型准确和丰富的多态信息量等特点，已成为第二代DNA分析技术的核心。

At polymorphic gene locus, the variance components of quantitative trait was described as follows:VA=2βp and VG=p′Xp-G2 in which p=column vector of polymorphic allele frequencies,β=row vector of2,X=［a2ij］i×i matrix,aij=genotype value,and G=population mean.

数量性状相对多态座位的加性方差和遗传方差分别为VA=2βp和VG=p′Xp-G2，其中p′和p分别表示多态等位基因频率的行向量和列向量，X表示以基因型值平方为元素的矩阵，β表示以基因均效平方为元素的行向量，G为群体均数。

The simulation of design has been conducted by matrix method combined with iterative method.

操作型模型分别以T_0、T_K、处理量F_0、出料浓度x_等不同控制变量为未知变量并采用矩阵法结合迭代法进行操作模拟计算；在操作模拟计算的基础上，建立了复杂多效蒸发系统操作优化模型，该模型以浓缩成本最小为优化目标，以T_K和F_0为决策变量，采用遗传算法结合矩阵法求解。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。

Galvanizes steel pallet is mainly export which suits standard packing of European Union, the North America. galvanizes steel pallet is suitable to heavy rack. Pallet surface can design plate type, corrugated and the gap form, satisfies the different requirements.

镀锌钢托盘多用于出口，替代木托盘，免薰蒸，符合欧盟、北美各国对出口货物包装材料的法令要求；喷涂钢托盘适用于重载上货架之用，托盘表面根据需要制作成平板状、波纹状及间隔形式，满足不同的使用要求。
