Abstract: According to the general analytic expression of the wavefunction recently derived by Gu and Qian, we obtain the time variation of the probability density for three kinds of the variable mass harmonic oscillator under the action of a harmonic driving force .

Key words: Feynman path integral, propagator, wavefunction, probability density

摘要： 按照本文两位作者最近导出的波函数的一般解析表达式求得3种变质量谐振子在谐驱动力作用下其几率密度随时间的变化情况。
