动电的

When a rotating voltage vector is injected to the motor at standstill, there is a microinching when the voltage phase is line to the direct axis of the motor. Then the current will decrease due to the back electromotive force. The initial mover position is identified by this change.

电压相位和电机直轴重合时，产生的电磁推力超过负载阻力，电机有一微动，由于反电势的作用电流就会降低，通过检测电流矢量的变化来估计动子的初始位置。

On the basis of the analysis and comparison of some sensors, Eddy Current Sensor is selected, and its equivalent circuit, strength and depth of the eddy current, radial distribution of the current, axile intensity of the magnetic inductorium are all analyzed. The processing circuit of sensors signal is designed. Because of coupling problem of the sensors, differential measurement of sensor is applied.

在分析比较各种传感器特性的基础上，选择了电涡流传感器作为转子位移的检测元件；分析了电涡流传感器的等效电路、涡流强度和深度、涡流的径向分布、线圈轴上的磁感应强度；设计了传感器的信号处理电路；对于传感器始终存在的偏置耦合问题，提出了传感器差动测量的方法。

By using the"energy equivalent method",thepiezoelectric structure damping is equivalent to a viscosity damping,according to which the quantitative relationship between the response time ofan one-dimensional piezoelectric actuation system and the mechanical qualityfactor of its piezoelectric material.The inexactness of the previouscorresponding relationship obtained by Taylor is analyzed.

用能量等效法将压电结构阻尼等效为粘性阻尼，建立起一维压电致动系统的响应时间与压电材料机械品质因子之间的定量关系，分析了以前由Taylor所获得的定量关系的不严格性。

So, the Lifter transforms the electric energy into an electrokinetic thrust Vs the medium where it moves (there is no moving part, it flies silently and it is highly maneuvrable)...

所以说，飘升机是在它运动的媒质中把电能量转换为动电推力并反作用于周围媒质。

Based on the 4 nodes element used for piezoelectric composite laminate plate and finite element method,and using sensitivities of structural displacements with respect to actuator voltages,the static deformation control considering smoothness requirement for platelike adaptive structure with piezoelectric material layers as actuators is studied in this paper.

基于四节点压电复合材料层合板单元和相应有限元分析方法，利用结构位移对电压的灵敏度，对以压电材料为作动器的板壳自适应结构，进行了考虑平整性要求的静力变形控制。

We also did psychophysics experiment of human saccade response during auditory and visual stimuli which directly related with SC functions. We find some correlations between the STDP time window and the plasticity of human saccade response time.

我们还研究了和上丘功能直接相关的人在视觉听觉刺激下眼动反应的心理物理实验，结果表明人眼动反应时间的可塑性和电生理的时间窗口有相关性。

The final step is the dissection of the internal thoracic artery and vein to avoid damage by compression, coiling, kinking, or stretching of the vascular pedicle.7 Usually, the internal thoracic artery and vein are exposed at the level of the first rib; branches are clipped next to the main branch while the other ends of the branches are either electrocauterized or clipped.

最后一步则是胸廓内动静脉的解剖，避免压迫、卷绕、纽绞或牵扯血管蒂。一般胸廓内动静脉可在第一肋水平显露；主支旁的分支可以结扎切断，其他分支可以双极电凝或结扎切断。

From our daily necessities to Office appliances, to power the rapid, ornamenting, process, product, we will need more and better more useful external packaging, while the majority of these wrappers will depend on the transfer, as a result of the master, a broad and deep market space.

从我们的常日糊口用品到办不私用具，再到电迅、点缀、工艺等各动各业的产物，都必给更多更好更适用的内部包装，而这些包装不小局部都给靠不停印来达成的，因此不停印动业具有很普及和很深的阛阓不工夫。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
