质点沿水平转盘任一弦运动时加速度的推导

Deduction of the Acceleration of a Particle When it Moves along any one of the Strings of a Horizontal Turning Disk

水平转盘以匀角速ω转动，一质点沿盘的直径以匀速率ｖ’作相对运动，在惯性系中考查质点的运动，发现有科里奥利加速度存在。这是一般教科书中常用的手法。本文则从质点沿任一弦这动的情况来引出此项加速度。

When a horizontal turning disk turns at a uniform angular velocity ω and a particle makes at a uniform speed υ’ in the inertial system examining the movement of the particle, people discover that there exists the Coniolis acceleration. This is a general way in textboors. In this article, we deduce this acceleration, in another way, at acase when the particle moves along any one of the strings.
