Methods Four pairs of primers were designed from toxin sub-unit A gene, O139 special gene, Haemolytic subunit A gene and Toxin coregulated pilus subunit A gene. Multiplex PCR was established to simultaneously detect those four genes.

分别针对霍乱弧菌肠毒素A亚单位基因、O139群特异基因、霍乱弧菌溶血素A亚单位基因和毒力协同调节菌毛A亚单位基因设计引物，建立多基因PCR方法。

OBJECTIVE: To investigate if a kind of pluripotent stem cells with more primitive character can be isolated from adult tissues.

目的：探讨从成体组织中能否分离出一群具有独特表型的更为原始的多潜能干细胞。

On the knowledge of vibration of polyatomic molecules, it has gonethrough the change of two stages: from normal mode model to local modemodel. In present, there mainly are two methods to deal with this problem:the traditional approach, namely ab initio, based on solving Schr〓dinger equa-tions of molecular vibration, and the algrbraic approach based on group theory.

在对多原子分子振动问题的认识方面，人们经历了从简正模模型到局域模模型转变的过程，而在处理方法上目前主要有两种：基于求解薛定谔方程的从头计算法和基于群论方法的代数方法。

Aim: to determine subpopulations and cytokine expression of na ve and memory t cells by polychromatic flow cytometry.

目的： 利用多色流式检测技术探讨初始和记忆t细胞亚群与细胞因子表达之间的关系。

AIM: To determine subpopulations and cytokine expression of nave and memory T cells by polychromatic flow cytometry.

目的： 利用多色流式检测技术探讨初始和记忆T细胞亚群与细胞因子表达之间的关系。

As an NP-hard problem, this model has no solution based on polynomial algorithm at present. Therefore, an adaptive and polymorphic ant colony algorithm has been brought forward to solve the VRPMC.

由于该模型是一个NP-hard问题，目前还没有多项式算法求解，又提出了采用自适应的多态蚁群算法来对其进行求解的策略。

Methods According to the classification of east, middle and west areas in China, as well as urban and rural, the multi-stage cluster probability sampling was used to select randomly total 17607 children under 5 years, whose weight and height were measured in standard method.

方法采用多阶段分层整群随机抽样的方法，按照东、中、西三类地区和城市、农村的分层原则，在全国选取17607名5岁以下儿童，测量儿童的身高和体重。

Our author is voluminous; he continues to write and publish with as much praiseworthy and indefatigable prolixity, as if his efforts were crowned with the brilliant success that so justly attends those of Eugene Sue.

我们的作者是一个多产者；他持续地写作，仿佛一个值得称赞的，不知疲倦的唠唠叨叨的作家，好象他的努力被冠以辉煌的成功，加入了苏·尤基那群人似的。

According to the survey for the whole country to the provinces, autonomous regions and municipalities for the whole meeting, to take layered, multi-stage cluster probability sampling method proportional.

据介绍，这次调查以全国为总体，以各省、自治区、直辖市为次总体，采取分层、多阶段、整群概率比例的抽样方法。

The objective is to subjugate and discourage the people, because that allows the elite to continue to rule unopposed.

其目的是压制和打击人民的积极性，因为这可以让实权派继续统治不会沦为反对派。

GOD,this is the second time you vanquished me!

天啊，这是第二次你打败了我！
