因此可以说类太阳振动的研究是传统的日震学与恒星结构和演化相结合的产物。

So, the study of solar-like oscillations came from helioseismology combine with the stellar structure and evolution.

基于拉格朗日法建立振动筛系统动力学模型，分析出了该系统的固有频率、主振型及系统的响应。

Based on Lagrange dynamics model of vibration machinery system is established. Natural frequency, vibration model and systemic response are worked out.
