| 61. | During periods of light winds or reduced river flow coastal current often become so weak as to be barely |
| 在淡淡轻风或河道流量减小时，海岸流变得很弱，几乎看不出来。 |

| 62. | But we do not yet have a circuit-breaker design that can cut off the extraordinary current that would |
| 但目前还没有设计出一种断路器，可截断在超级电缆上流动的超大电流。 |
|
|
| | |
| 63. | When current is withdrawn from the battery, chemical actions take place to produce the flow of current |
| 当从蓄电池中提取电流时，蓄电池内发生化学作用，使电流流动。 |
|

| 64. | only its (low) leakage current to the circuit but should the sensor be short-circuited the resulting current |
| 正常情况下，二极管处于反向偏置，只有很小的漏电流；当输入端窜入高压时，二极管正向导通泻放掉大电流，保护放大器。 |
|

| 65. | The car key opens a path so that electric current can flow from the car battery to the cranking motor |
| 司机开车的第一件事情就是把钥匙插入点火锁，转动钥匙。汽车钥匙接通电流，以使电流从蓄电池流向发动机。 |
|
|
| | |
| 66. | Instead, it decays, allowing a current to flow for a short time. |
| 我们需要一个超电压来传送一个能够通过电化学降的电流，当电流被断开后，超电压不会马上降到零位，而是衰减，电流还会在短时间内流动。 |
|
|
| | |
| 67. | If the circuit is broken at a point, so the current cannot flow, it is an open circuit. |
| (1)电路,(2)线路:(1) 电流可以流通于电器元件和导体间的系统;这个情况,称为[闭路].如果于某处切断电路以致电流不能通过,则儿为[开路]或[断路]. |

| 68. | circuit, causes the loop to open or causes absence of signal.In a polar circuit it causes the loop current |
| 在中性电路中，引起环路断开或造成信号消失的一种脉冲（信号）。在极性电路中，空号脉冲促使环路电流向传号脉冲相反的方向流动。空号脉冲相当于二进制零。 |
|
|

| 69. | Fault A fault is any unintended flow of current outside its intended circuit path in an electrical system |
| 故障故障是指在电力系统中任何电流跑出正常电路以外的情况。 |
|
