一 结构原理 教学用付科摆的主要结构,如图1所示。整个装置放在四面透明的玻璃罩内,以增加可见度并防止空气热运动对实验的影响。机架是由较好的角钢焊接的,保证了摆在运行中的稳定性,摆由带指针铸铁球、吊
A structural principle The main structure of teaching pendulum is shown in Figure 1. The entire device was placed in a four-sided transparent glass cover to increase visibility and prevent the thermal effects of the air on the experiment. The frame is welded by better angle steel, which guarantees the stability during operation. The cast iron ball and crane
