一种测量重力加速度的空心摆筒实验装置
摘要：
本发明提供了一种数据处理准确便捷，适合于学生操作的一种测量重力加速度的空心摆筒实验装置，所述的空心摆筒实验装置由空心摆筒和两套高度相同半径不同的圆柱形砝码组成，本发明通过空心摆筒与圆柱形砝码组成一个复摆系统，首先获得添加了不同数量的砝码后复摆系统的摆动周期，再通过分析两套砝码对复摆系统摆动周期的影响，来获得重力加速度的计算公式。相比于现有方法，本发明依靠拟合直线的斜率来获得重力加速度，具有实验方法简单，数据处理便捷的特点，既避免了复杂繁琐的实验数据处理过程，又提高了实验数据的精度，所述实验装置便于操作，原理易于理解，适合于物理实验教学。
摘要（英）：

The invention provides a hollow pendulum barrel experiment device which processes data accurately and conveniently, is suitable for operation by students and is used for measuring gravity acceleration. The hollow pendulum barrel experiment device is composed of a hollow pendulum barrel and two sets of cylindrical weights with the same height and different radiuses. A compound pendulum system is formed by the hollow pendulum barrel and the cylindrical weights, first a swing period of the compound pendulum system is obtained after different amounts of weights are added, and a gravity acceleration computation formula is obtained by analyzing influences of the two sets of weights. Compared with an existing method, the gravity acceleration is obtained by fitting a slope of a straight line, thehollow pendulum barrel experiment device has the advantages of being simple in experimental method and convenient in data processing, the complex experimental data processing process is avoided, experimental data precision is improved, the experiment device is convenient to operate, a principle is easy to understand, and the experiment device is suitable for physics experiment teaching.
