Damp Vibration with Amplitude Mutation According to Arithmetitical Array

由简谐振动的推论 ,研究阻力大小不变的阻尼振动 。

From the deduction of simple harmonic motion, the article deals with the research of damp vibration with definite resistence size, and comes to the conclusion that the amplitude decreases progressively and evenly.
