摘要
本文从远动方程解得油滴自由下落的速度与时间的关系,由此证明油滴自由下落时几乎立即达到匀速运动状态。此外,并提出了较为精确的油滴半径计算公式,以及由于空气粘滞系数η值随温度变化,对其进行修正的必要性及其方法,从而能提高了密立根油滴实验结果的精确度。
Velocity of free-fall oil drop in terms of time is obtained by solving the equation of motion in this paper. It proves that the oil drop reaches to the uniform motion state immediately when falling freely. In addition, a more precise formula for calculating the radius of oil drop is put forward. As the coefficient of viscosity of air η changes with temperature, it is necessary to adjust the calculation. The adjusting method is provided in this paper, so that the precision of the Millikan's experimental result is improved.
