A series of rings arranged up and down the inner wall of a container might also impede the liquid oscillations .
在容器内壁增加一系列从上到下的圆环也可能阻碍液体的振荡。
But no electronic systems exist that can directly count these oscillations .
但是，目前没有哪个电子系统可以对如此高的振动频率计数。
In addition to the precise age measurement , wmap has been able to detect small acoustic oscillations ( the cosmic equivalent to sound waves ) in the cmb radiation , and the signature detected suggests primordial helium was generated in predicted quantities in the early stages of universal evolution .
One method looks for the effects of sound waves which originated in the big bang : baryon-acoustic oscillations ( bao ) .
其中一种方法在寻找起源于宇宙大爆炸的音波效应：重子声学振荡（bao）。
Just as the ticking of a watch arises from the escapement mechanism connected to the gears and hands oscillations within the cavity are recorded electronically .
