您要查找的是不是：
- The electrical signal is generated through an influx of calcium into the cells in the SA node, causing a change in oltage which creates the current. 这个电信号是通过窦房结细胞的钙离子的内流产生的，它导致了膜电位的变化而由此产生了电流。
- But we are may demodulate through some technologies these changes, again transforms the electrical signal to let our sensation. 而我们是可以通过一些技术把这些变化解调出来，再转变成电信号来让我们感知。
- The Electric Point Machine (EPM) is an important one of railway electrical signal devices. 道岔转辙机是一种重要的铁路电气设备，它是以电动机为动力改变道岔开通方向，并能反映道岔位置状态。
- These cells are essential for neurons to communicate with one another because they insulate the long axons between neurons, preventing the electrical signal carried by the axons from dissipating. 这些细胞会包围在神经细胞的长轴突外，使它们彼此绝缘，如此可防止轴突所携带的电讯号消散开来，因此寡突细胞是神经细胞互相沟通所不可或缺的。
- There is a fault in the electrical system. 电路系统出了故障。
- Actually, you would outrun the electric signal on its way from the switch to the bulb. 实际上，你将会比电信号从开关到灯泡还要快。
- Eery thought, feeling and action originates from the electrical signals emitted by dierse brain cells enmeshed in a tangle of circuits. 每个思维、感觉和动作都源自大脑中分布于电路一样的环路中的各种脑细胞发出的电信号。
- The research team has found a way to accurately place sensors in each fibre and co-ordinate the electrical signals they send when light falls on them. 这个研究小组找到了方法准确地在每个纤维上安置传感器，并对光照在上面时，协调传感器发出的电信号。
- It's quite clear that the electric car is technically feasible. 电动汽车明显在工艺技术上是可行的。
- Don't meddle with the electrical wiring: you're not an electrician. 别瞎动电线线路，你又不是电工。
- These, in turn, generate a structure called the myelin sheath, which insulates nerves against leakage of the electrical signals that carry their messages around. 这些，反过来，产生一种叫做髓鞘的组织，它能隔离神经细胞防止电信号周围携带的信息泄漏。
- A cardiac arrest is a disruption of the electrical signals that trigger heartbeats, causing the heart to beat erratically so that it does not pump blood effectively. 心脏骤停是指引发心跳的电信号发生中断，造成心跳紊乱,进而导致血液不能有效地循环。
- Please turn off the electric power. 请把电源关掉。
- The electricity failure paralyzed the water supply. 停电使水供应陷于瘫痪。
- While recording,the sound is changed for the electric signal by mike.After magnified,it is transcribed on the tape.While playing,the magnetic signal is changed for the electric signal. 录音时，声音通过话筒转换成电信号，经放大器放大后，由偏磁电电流驱动磁头录制在行走当中的磁带上。
- Fail to pay and they'll cut off the electricity. 你(如果)不付款，他们就要断电。
- A device that attenuates an electrical signal. 衰减器，减压器使电子讯号减弱的装置
- The electricity failure paralysed the water supply. 停电使水供应陷于瘫痪。
- Connect the fridge (up) to the electricity supply. 接通冰箱的电源。
- We will put the electrical work out to subcontract. 我们将把电气工作转包出去。
