随着光前驱和主波包通过第二组铷原子，科学家就可以对这两个光子成分的速度进行测量。
As the optical precursor and main wave packet traveled through a second group of rubidium atoms, the scientists took measurements on the speed of the two photon components.
我们确定，主波包传播的速度不能超越以光速c传播的前驱。
We are sure that the main wave packet cannot travel faster than the precursor, which travels at c.
小波包分解本身对信号的奇异点十分敏感，此特点可以用来跟踪电机振动速度信号。
Because the wavelet packet decomposition is very sensitive to signal of the strange point, this characteristics can be used to follow the velocity signal of motor vibration.
