对称非线性弹簧振子的周期特性

The period of a symmetric nonlinear oscillator

通过计算机编程 (QuickBasic)描绘对称非线性弹簧振子振动的特性曲线 ,使难懂的物理过程变得直观、形象 .对称非线性弹簧振子的振动是一种周期性振动 ,但不是严格的简谐振动 ,其振动周期随非线性系数。

The characteristic of the vibration of a symmetric nonlinear oscillator is demonstrated by using 'Quick Basic'programs. The vibration is periodic, but is not strictly as simple harmonic motion. When the nonlinear coefficient or the amplitude changes, the period will deviate from that of simple harmonic motion.
