    "abstract": "By using a test-function method, we construct $n$ exact solutions of a\nquantum harmonic oscillator with a time-dependent \"spring constant\". Any $n$-th\nsolution describes a wave-packet train consisting of $n+1$ packets. Its center\noscillates like the classically harmonic oscillator with variable frequency,\nand width and highness of each packet change simultaneously. When the\ndeformation is small, it behaves like a soliton train, and the large\ndeformation is identified with collapse and revival of the wave-packet train.",
