浅谈频谱治疗的物理学原理魏堃（包头医学院物理教研室，包头０１４０１０）先介绍一个简单而有趣的实验。将一条线绳水平地固定在两根立柱上，再用细线分别系住Ａ、Ｂ两个小球。将Ａ球的拉线固定在水平悬线上。将Ｂ球的拉线跨过水平悬线并用手拉住。（见附图）令Ｂ球摆动... Talking about the Physics Principle of Spectrum Therapy Wei Kun (Department of Physics, Baotou Medical College, Baotou 014010) First, a simple but interesting experiment is introduced. A line of rope is fixed horizontally on two columns, and then tied with thin lines A, B two balls. Fix the pull line of A ball on the horizontal hanging line. Pull the ball of B ball across the horizontal suspension line and hold it by hand. (See photo) Order B ball swing ...
