摘要
伽尔顿板实验仪是直接或间接验证麦克斯韦气体分子速率分布律、气体的能均分定理、气体压强的产生、气体温度产生的重要仪器.旧式的伽尔顿板实验仪由于受到动力学效应的约束,显示出明显的局限性.通过对原有仪器进行改进,使每行钉子在水平方向往返运动,增加了钉子与小球的碰撞概率,实验结果更接近统计规律.
Galton board instrument is important because it can verify Maxwell velocity distribution law and the principle of equipartition~ it can explain the principle of gas pressure and temperature. Be- cause of the constraint of kinetic effects, Galton board experiment instrument shows obvious limita- tions. This paper improved the structure of instrument, and each line nails reciprocally vibrated in the horizontal direction. The collision probability between nails and ball was added and the experiment re- sult more approched with the statistical law.
