摘要：

A new application of parametric-amplification principles, which are used in radio electronics, is considered for amplifying and processing mechanical oscillations that bear information about the state of physical media and the processes in these media. This approach is shown to be useful in designing highly sensitive receivers of mechanical and acoustic oscillations.
