Abstract

A perturbation filtration system for physical quantity measurement of weak resonance signal is introduced. With this system，the perturbation of a strong damped vibrating system is decreased and the resonance state of the vibrating system can be determind. The relative physical quantity can be measured accurately.

Key words： perturbation filtration system; resonance state; Young modulus; acoustic velocity measurement
