非电量测量中调幅谐振法

An New Investigation on the Amplitude Modulation Method for Non-electrical Quantity Measurement

叙述了非电量测量中调幅谐振法技术,提出在调幅谐振法中引入比较测量从而使灵敏度得到很大的提高。并从原理、数学推导以及简单的实验证明能提高灵敏度。

The technology of the amplitude modulation method in non-electrical quantity measurement is described. The authos states that the sensitivity will be well enhanced if comparison measurement is involved in the amplitude modulation method. This concept is verified by principle, mathematic derivation andsimple experiment.
