【Abstract】 Using coordinate-transformation we transformed a harmonic oscillator with ti me-dependent mass and a time-dependent inverse potential into a harmonic oscil la tor with time-independent mass and a time-independent inverse potential accord in gly. In terms of the relation between these two different harmonic oscillators’ propagators we derived the exact wavefunction of the former by Feynman path-int egral. We also discussed the harmonic oscillator with more additional potentials .更多还原
