The principal resonance of a second-order stochastic oscillator under combinedharmonic and random parametric excitations is investigated.
研究了二阶线性系统在谐和与随机噪声联合作用下的主共振响应和稳定性问题。

When the response frequency is equal to the eigen-frequency of a derived system, harmonic resonance, super-harmonic resonance and combinedharmonic resonance may occur.
当响应频率等于派生系统的固有频率时，将会出现主共振、超谐共振和组合共振现象；
