利用双光栅开展设计性实验的探讨

Discussion on Development of Designed Experiment Using Double-grating

探讨了利用双光栅微弱振动测量仪开设设计性实验——测量微小物体质量的方法、步骤、数据处理以及误差分析,阐述了该实验对于开设大学物理设计性实验的启示.

This paper firstly discusses on all the aspects （i.e. the ways, steps, data processing and error analysis of measuring tiny mass） of developing designed experiment by using the double-grating weak vibration measuring instrument. And then it expounds the great insight this experiment bears for the development of physical experiment of a university.
