对气轨上简谐振动周期测量公式的修正

The modification for the metrical formula of simple harmonic motion cycle

在气轨上测量简谐振动周期时摩擦力几乎为零 ,但粘滞摩擦阻力的影响却是客观存在的 .作者通过对滑块在运动过程中的阻力分析 ,从理论上导出了在考虑粘滞阻力时的附加周期公式 。

In the gas track experiment, the friction is nearly equal to zero when the simple harmonic motion cycle is measured. However, the effect caused by the sticky frictional resistance on the magnitude of the metrical cycle is existed, through detailed analysis of the resistance in the course of motion as a slippery object moving back and forth on the gas track, theoretically, the additional cycle formula reflecting the sticky frictional resistance is deduced theoretically.
