1·There is another class of lasers, however, that pulse, oscillating between an "on" stage, where light is produced, and an "off" stage, when the amount of light is dramatically reduced.
脉冲激光器是另一类的激光器，它的脉冲是在“开”与“关”两种状态的振荡之间产生。 当激光器处于“开”的状态，产生光，在“关”的状态，光量显著减少。
2·Extinguishing big fires still requires conventional methods, but oscillating electrical fields have snuffed out smaller fires.
扑灭大火仍需采用传统方法，但振荡电场可以用于熄灭小型火势。
3·During REM sleep, our brain waves-the oscillating electromagnetic signals that result from large-scale brain activity-look similar to those produced while we are awake.
在REM睡眠期里，我们的脑电波(由大规模的脑力活导致的振荡的电磁信号)貌似与我们清醒时所产生的脑电波雷同。
4·At extremely cold temperatures, it goes quantum: it exists in an oscillating waveform spanning an excited state, an unexcited state, or both simultaneously, all controlled by electrical currents.
在极低的温度下，它发生量子：它存在于一个振荡波形中，波形可能呈现激发态、未激态、或两者同时兼具，这都取决于电流的控制。
5·The Japanese company has been riding robust growth here, peddling commodes with sleek designs and features such as oscillating bidets, air fresheners and blow dryers.
这里日本公司一直拥有最强劲的增长势头，他们兜售设计新颖和品质优良的马桶，例如那些有振荡坐浴盆，空气清新剂和风干机的。
