本文着重介绍,参照Magnus回转仪原型.用我们自己设计研制的教学回转仪,与高压脉冲火花发生器和特制的空间极迹记录板组装在一起,用线绳驱动转子,定量的或者定性的研究了刚体绕定点转动的几个基本的规律.教学实践表明,这样的研究有助于把刚体力学有关回转仪的理论教学与实验联系起来. This article focuses on the introduction of Magnus gyro prototypes. Using our own design and development of teaching gyroscopes, assembled with high-voltage pulsed spark generators and specially made space pole tracers, using wire ropes to drive the rotors, quantitatively or qualitatively. Some basic rules about the rigid body rotating around the fixed point. Teaching practice shows that this kind of research helps to link the theoretical teaching of rigid body mechanics with gyroscopes and experiments.
