摘要
运用垂直轴定理对扭摆进行改进,经改进后的扭摆不仅提高测量转动惯量和材料切变模量的准确度,而且可以直接验证垂直轴定理,了解垂直轴定理的应用。
This paper put forward a method to improve a torsion pendulum using vertical axis theorem, which can enhance the moment of inertia and the accuracy of material＇ s shearing modulus and verify the vertical axis theorem and understand the application of vertical axis theorem.
