您要查找的是不是：
- The amplifier input is a voltage proportional to the photocurrent signal produced by a photodiode, which is irradiated by a modulated light beam at the same chopper frequency. 放大器输入为电压信号，与光敏二极管产生的光电流信号成比例。调制光柱以断路器同样的频率照射光敏二极管。
- This approach automatically results in a current frequency twice as high as the chopper frequency so that the ripple of the phase currents is 22 kHz, i.e. it is outside of the audible range. 这种做法的结果会自动在一电流频率高一倍菜刀频率，使纹波的阶段，电流是22千赫，即是以外的发声范围。
- He varied the transmission frequency. 他变换了无线电传送的频率。
- A unit of frequency equal to one cycle per second. 赫兹频率的单位，等于每秒一周
- chopper frequency 间断频率,间歇频率,遮光频率
- Fatal accidents have decreased in frequency over recent years. 近年来死亡事故发生的频率已经下降。
- A medevac chopper;a medevac mission. 救伤直升机；医务救助任务
- Chopper They sure use some funky evasive maneuvers. 它们确实用了一些滑稽的躲避动作。
- We can often correlate age with frequency of illness. 年龄的大小往往与发病率有关。
- Chopper Did I lose him?Okay, time to regroup. 我甩掉他了么？好，是重新编队的时候了。
- Chopper Whoa! Those guys are really mad now! 哇奥！那些家伙真的生气耶！
- Accidents on that highway are happening with increasing frequency. 那条高速公路上车祸发生得越来越频繁。
- They all board the chopper en route to safety. 他们一家人登上了直升机，飞向安全地点。
- Chopper I had no idea he was such a wuss. 没想到是这样一个窝囊废.
- There are SUVs, souped up cruisers, and a chopper. 有越野车，淹没了巡洋舰，及一把刀。
- Chopper Man, I hate these guys. I really do. 伙计，受不了这些家伙们了。真的很讨厌耶。
- Chopper Booby's missile smoked the target! 小鸟的导弹命中目标。
- The fodder chopper needs to be reinforced. 这口铡刀该钢了。
