The maximum amplitude, stability and amplitude jump of main resonance describe the primary characters of a drive shaft.
传动轴主共振的最大振幅、稳定性、振幅突变性是其主要特性。

For obtaining a pulse series with a small amplitude ripple, an Erbium-doped Fiber Amplifier (EDFA) must be added into the primary experiment setup to enhance injection-modulation signal power.
Pulse signal is one of the most primary physiological signals, including the pulse frequency, the pulse rhythm, pulse-filling ratio, state of stream, state of motion, fluctuation amplitude and so on.
