| 摘 要： | 本文主要从能量守恒的角度,在稳定性要求的限制下,通过单摆的摆角分析,突破传统中小角度(θ<5°)的限制,把周期公式推广到大角度(θ<180°)的情况.我们的研究得出较为精确的阐述重力加速度的表达式,这将为单摆实验中测量重力加速度带来便利.

| Abstract: | With the perspective of conservation of energy, within the limits of stability required by the pendu- lum swing angle analysis, breaking through the limitations of traditional small angle, cycle formula was popular- ized to the case of large angles. The results show that present more precise exposition for formula of gravity of expression, which will bring the pendulum experiment, to measure the acceleration of gravity, more convenient. |
