Methods: 90 Sprague-Dawley rats were randomly divided into 3 groups: control group, emotional stress group and footshock group.

90只SD大鼠，随机分为3组：空白对照组、足部电击组和情绪应激组，采用反转录－聚合酶链作用技术，检测应激后不同时间点三叉神经节中CGRP mRNA水平的变化。

Methods Total RNA was extracted from the heart of adult SD rat and first strand cDNA was obtained by reverse transcription. Primers was designed according to the offered sequence in Genebank.

以成年SD大鼠心脏为实验材料，提取其总RNA并反转录；根据Gene bank中提供的大鼠TNNT2基因cDNA序列，利用PCR方法扩增此序列，并进行表达研究。

This design main be how average type beam drill electricity charge circuit be in progress design, main content include host circuit design, control circuit design, instruction circuit design and under the control of component choice, not bad come true Z3050 type beam drill starting, stop, be rotating, roll back and a few corresponding protection function.

本设计主要是多普通型摇臂钻床的电控线路进行设计，主要内容包括主电路的设计、控制电路的设计、指示电路的设计和控制元器件的选择，可以实现Z3050型摇臂钻床的启动、停止、正转、反转以及一些相应的保护功能。

According to four electric motors designing that primary data ascertains the host circuit be chief axis electric motor , rocker arm electric motor , hydraulic pump electric motor and cooling pump electric motor every one platform; Rotating , rolling back and protecting a function for the starting, stop realizing a drill machine

根据设计原始材料确定主回路电动机四台，即主轴电动机、摇臂电动机、液压泵电动机和冷却泵电动机各一台；为了实现钻床的启动、停止、正转、反转及保护功能，设计了相应的控制回路；同时为了对应电动机的各个动作，对其作出指示，设计了指示电路；然后换照电气选型原则，对元器件进行了选择。

On the modeling and optimization platform, models of two types of working mechanisms—reverse-turning six-bar linkage has been generated.

在机械设计研究所自行开发的建模平台上，对反转六连杆机构建立了参数优化模型，确定了变量系统，目标和约束系统，用优化软件进行了优化设计。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
