摘要
本文通过理论推导,得出在考虑空气粘滞阻力的情况下,用气垫导轨测重力加速度的实验近似公式,并给出重力加速度的修正项。
In this paper the approximate formula of the experiment of measuring gravity acceleration using air- cushioned guide way is obtained on the condition of considering the air friction drag by theoretical deduction. The corretion term of gravity acce1eration is given.
