钟面上m点n分时,时针与分针的夹角α之度数,有如下计算公式: α=|30m-5.5n| (*) 由时针与分针在钟面上的行程问题出发——假设两针从某整点m点的位置始,转到m点n分终,易推出(*)式。
In the case of m points on the clock, the angle α between the hour and minute hands is given by the following formula: α=|30m-5.5n| (*) Starting from the stroke of the hour and minute hands on the clock surface - assumption The two needles start from the position of m at a certain point and go to point m at the end of time. It is easy to introduce (*).
