On the normotensive rat, pretreatment with verapamil (0.25 ug/0.1 ul/site), the blocker of calcium channels, by microinjection into the rVLM bilaterally, not only caused a complete block effect on the elevation of BP, HR and the pressor response to defense stimulation by the subsequent microinjection of physostigmine, glucocorticoid or mineralocorticoid (the same dosage as mentioned above) into the same sites, but also led to a slight reduction on the basal cardiovascular activities to a certain extent.

四、在正常血压大鼠上预先用钙通道阻断剂维拉帕米(0.25μg/0.1μl/site)微量注射至双侧rVLM，不仅能阻断随后在同部位微量注射毒扁豆碱(0.4μg/0.1μl/site)、肾上腺糖、盐皮质激素(分别为40ng/0.1μl/site)所致的升压、加快心率、以及电刺激dPAG诱发的防御性升压反应，而且能引起上述指标不同程度的较弱的降低。

In this paper,temperature effects on piezoelectric materials are investigated theoretically and experimentally at first.

该文首先从理论上分析了温度对于压电元件的影响，并加以实验验证，据此提出了一种基于数字滤波器的温度补偿法。

If a voltage is applied to a piezoelectric crystal, its dimensions change.

如果一个电压被应用在一个压电晶体上，它的尺寸会改变。

On the basis of the above research, a reality piezoelectricity gyro SINS has carried out the test of static quiet.

Any flows greater than the capacity of the low flow diversion pipeline then flow into the park.The authors present an e'ectrical method by use of the pressure dif- ference transducer with the pitot tube which is installed in the pens- tock of prototype turbine to search for the law of dynamic flow unde?

作者提出一种装置在原型水轮机压力引水管道上的皮托管经差压应变传感器的电测方法，用以测量水轮机过渡过程中的动态流量变化规律；采用这种方法，首先在三座水电站中对原型水轮机各种过渡过程的动态流量变化规律进行了测量，并获得了较为满意的结果。

As an important part of the current work, great effort has been made in the experiment It is shown by mass of experimental results that the vehicle with ECC is placidity when it is starting-up and changing-gear, and the longitudinal comfortability and security are achieved anticipant.

实验研究是本项研究的重点工作之一，本文的所有实验均在Santana LX型轿车上实车进行，大量实验结果表明，装有电控离合器的车辆起步和换档平稳，纵向舒适性和安全性均达到要求，该系统开发是成功的。

If there is an input rotation rate on the vibrator,an induced voltage proportional to the angular rate will be produced in the direction perpendicular to the plane composed by the polarization axis and the input angular rate axis according to the Coriolis effect.

由PZT薄膜材料做成的平板沿厚度方向极化并受电激励产生厚度伸缩振动，当一输入角速度作用于振子，根据哥氏效应，则在极化轴和输入角速度轴组成的平面垂直方向上产生一正比于输入角速度大小的感应电压。

It is a bi-directional transport process, capable of moving Ca〓 in either direction across the plasma membrane.

心肌细胞膜上的钠钙交换体是一种双向的、生电性的离子交换系统，对于维持心肌细胞钙稳态非常重要。

Pitched at the divide between art and industry, poetry and entertainment, it goes darker and deeper than any Hollywood movie of its comic-book kind — including "Batman Begins," Mr. Nolan's 2005 pleasurably moody resurrection of the series — largely by embracing an ambivalence that at first glance might be mistaken for pessimism.

游离于艺术和工业、诗情和娱乐之间，它比任何漫画改编的好莱坞电影都要黑暗深沉——包括诺兰2005年的前作《蝙蝠侠：侠影之迷》，它带来了此系列中令人愉悦的情绪化风格的回归——这在很大程度上是因为包含了矛盾情绪，让观众在最初的一瞥中误以为是悲观的色彩。

Under the conditions to consider the influence of the inertia of loading side and the stiffness of torque sensor,the dynamic models are established,the conclusion that the superfluous moment is related to the motion velocity,acceleration,and the differential of acceleration is presented.0n the basis of this dynamic model,a more effective control method to reject to extraneous moment from the view point of the division and cooperation of the function of the controller,i.e.hybrid control method,is proposed.

在考虑力矩传感器刚度和加载侧惯量影响的情况下，建立了电液力矩加载系统的动态模型，指出多余力矩不仅与运动速度干扰有关，而且还与运动加速度干扰和加速度的变化率干扰有关。在此基础上给出了一种从职能分工角度抑制多余力矩更有效的控制方法——混合控制法。

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。
