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。

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。

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。
