扭摆的故事──简单的仪器与重要的成果

Story of the Torsion Pendulum──a Simple Device with Important Uses

本文从扭摆内耗仪的发明和应用这一侧面来说明用简单的仪器设备也能够得到重要的成果．文中详细介绍了作者根据实验室通用的古典扭摆的启发来创制扭摆内耗仪的经过，以及作者应用这项简单仪器所获得的大量成果．作者创制扭摆内耗仪的指导思想是辩证唯物主义的认识论，即根据事物的普遍联系的法则把在一个领域里熟悉的道理有针对性地转用到另一领域．作者还谈到了由低到高不断发展的过程，举出了创制更精密的各种类型的扭摆的几个例子．

The argument that important results can be obtained by using simple equipment is pat forward from the aspect of the discovery and application of the torsion pendulum for internal friction measurement. The development of the torsion pendulum for internal friction measurement, inspired by the orthodox torsion pendulum commonly used in physical laboratories is described in great detail as well as numerous important results obtained by using this simple apparatus. The fundamental idea in developing the torsion pendulum for internal friction measurement is the theory of dialectical materialism, i. e. to convert well ^known knowledge in one field to another field according to the universal rule of drawing inferences about other cases from an instance. Furthermore, following the viewpoint of continuous development from a low to a high level, the author describes examples of various versatile apparatus derive from different versions of the torsion pendulum of high precision.
