摘　　要：讨论了受迫振动系统发生位移共振、速度共振、加速度共振和能量共振的条件及其特点。主要从四种共振发生的频率条件;共振时的振幅;共振发生时,驱动力与阻力所做的功或功率之间的关系进行分析和讨论。The conditions and characteristics of four kinds of resonance （displacement resonance, velocity resonance, acceleration resonance and energy resonance）produced by linear forced damped oscillation are discussed in this paper. The frequency conditions, the amplitude and the relationship between the work or power done by the driving force and the opposing force are also discussed in different kinds of resonance.
