当发电机的外接负载不对称时，转子的固有频率一分为二，转子的振动在原来单频振动的基础上，产生了双重共振现象。
Its natural frequency falls into two parts when the loads exerted on generator rotor are asymmetrical. Dual resonance phenomenon appears based on the former single frequency vibration.
考虑被压实物料的不对称滞回特性，建立了振动压路机振动轮-车架系统的二质量运动模型。
A two-mass model of the vibration compacting roller and its frame is established with consideration of materials asymmetrical hysteresis.
正常人中除1例声带振动轻微不对称外，其余4例未发现异常。
