PMX caused DNA damages in murine embryonic stem cells, oxidative stress injuries of mice and apoptosis of embryonic stem cells, leading to abnormal closure of neural tube and ultimately NTDs.

Genetic algorithms ( GA) using ordinal strings must use special crossover operators such as PMX, CX and OX, which is very bother.

传统的序号编码遗传算法（GA）使用PMX、CX和OX等特殊的交叉算子，这些算子实施起来很麻烦。

But, genetic algorithms using ordinal strings must use special crossover operators such as PMX, OX and CX, instead of general crossover operators.

但是，序号编码的遗传算法不能在任意两条染色体的任意位置进行交叉，必须使用PMX，CX和OX等特殊的交叉算子，这些算子实施起来都很麻烦且效率不高。

In addition, the PMX operator as well as other genetic operators for these two problems are very efficient, and so is the responding program.

另外，本文针对指派问题和排序问题提出的PMX交叉算子以及设计的运行程序非常有效。

Besides, folate levels in embryotic tissues were also significantly reduced by PMX treatment.

，同时PMX明显降低实验组的胚胎组织叶酸水平。

In the second section, this paper outlines the definition of the QEP and its theoretical roots, then details the four ways it operates and its six mechanisms, and finally seriously analyzes the differences between it and the traditional easing monetary policy.

首先从理论角度，本文概述了定量宽松货币政策的定义和理论根源，详细阐述了货币政策的四种操作方式和六项传导机制，最后分析其与传统的积极宽松货币政策的区别。

We also have completed its circuit diagram. We developed the software of 2407A which included the configuring of the system, exterior interrupt, counting of the Quadrature Encoder Pulse ( QEP) signal and serial communication etc.

编制了2407A的软件，其中包括系统的配置、外部中断、正交编码脉冲信号的计数和串口通信等部分程序，程序的开发采用了CCS2.21。

By applying the projection techniques, we derive two block second-order Krylov subspace methods. These methods are applied to the QEP directly. Hence they preserve essential structures and properties of the QEP.

利用投影技巧给出两种块二阶Krylov子空间方法，这两种方法都直接应用于二次特征值问题，从而保留了问题的结构和性质。

In this context, America, Japan and Europe implemented the Quantitative Easing Policy ( QEP) in succession intending to stimulate demand, revive the economy and prevent a recession.

在这种经济金融大背景下，美国、日本、欧洲先后实施量化宽松的货币政策，意图刺激需求，振兴经济，防止衰退。

As a result, the interface card can generate high-precision pulse signals and can be used in detection of quadrature encoder pulse ( QEP) signal.

其主要功能是输出高精度的脉冲，对正交编码脉冲信号进行检测。

The catalytic reduction desulfuration on cobalt oxide was investigated using UBI QEP method.

Different epileptic symptoms appeared about 10 minutes after the administration of PNC in rats, including resting, staring, squatting and shaking like wet-dog.

大鼠给予青霉素后10min左右出现不同程度的癫痫发作症状。表现为不动、凝视、蹲伏、湿狗样抖等。

Ammonia originates mainly from PNC in skeleton muscles in high intensity exercises, and from BCAA ( branched-chain amino acids) in exhaustive endurance exercise.

氨的主要来源：短时间高强度运动为骨骼肌的嘌呤核苷酸循环，长时间力竭性运动主要与骨骼肌大量摄取支链氨基酸有关。

There are many studies on the phonetics of QIE YUN but the study from the point of the author's linguistic view is seldom seen.
