摘要： 运用跃变旋转矢量法，即通过旋转矢量的起点、长度和相位的变化规律对受到空气弱阻尼作用和滑动摩擦力作用的弹簧振子的振动进行了研究．讨论了在滑动摩擦力作用下空气阻尼为临界阻尼和欠阻尼情况下的弹簧振子的运动，根据阻尼和初值情况得出不同的振动曲线．并对弹簧振子4种相图和相图旋转矢量进行了比较．
关键词: 弹簧振子, 空气阻尼, 滑动摩擦, 旋转矢量
Abstract: A dynamic rotation vector, including its starting point, length and phase change according to certain rules, is used to research the vibration of spring oscillator under sliding friction and air small damping. The vibration of spring oscillator is also studied under sliding friction and critical air damping （ or large air damping） , the curves of four kinds are given according to the initial value and damping. Four phase diagrams and phase diagram rotation vector of spring oscillator are analyzed.
Key words: spring oscillator, air damping, sliding friction, rotating vector
