In another experiment , an oscillating electric field was used to set the ion in one clock jiggling back and forth at a speed of about 10 metres per second , or 36 kilometres per hour .
This transition to living in the sea involved changes from paddling with limbs to undulating the body to oscillating a tail , such as the horizontal tail flukes in modern whale species .
这种转变包括从用前肢划水到身体波动再到尾巴摆动,就像现代鲸鱼的水平尾鳍。
The speed that the waves travel is how fast the waves are oscillating in time multiplied by the size of the step the waves are taken per period .
波传播的速度是波在时间上振荡得有多快乘以波每周期的步长。
Basically , the frequency is just a measure of how fast the wave is oscillating .
基本上,频率就是一个波振荡得有多快的量度。
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 .
This is the equivalent of zapping a stationary object with an oscillating magnetic field of the sort used in mri .
这相当于不断摆动mri中的磁场,并令其轰击某一静止物体。
Previous experiments have shown that applying a constant electric field created small effects on flames , but cademartiri 's work used an oscillating electric field to greater effect .
