引言自然现象中的自激振荡有线性振荡和非线性振荡。但根据看法也可分为正弦振荡和弛张振荡。从能量方面观察这些振荡,能量补充方法也各有特点。笔者试从能量观点考察各种振荡,将其分类。机械振荡和电气振 INTRODUCTION The spontaneous oscillations in natural phenomena have both linear and nonlinear oscillations. But according to the view can also be divided into sinusoidal oscillation and relaxation oscillation. From the energy side of these oscillations, energy replenishment methods also have their own characteristics. I try to examine all kinds of oscillation from the energy point of view, its classification. Mechanical oscillation and electrical vibration
