摘要：
Using Feynman's method of disentangling operators, an exact expression of evolution operator of harmonic oscillator with time-varying frequency is obtained. The parameters in this expression are related tb the time-varying frequency directly. Some implications ate further investigated, including general form of linear and quadratic invariants and evolution of Wigner function.
