摘要
在用比重瓶测量小固体的密度时,将小固体的采样质量与实验结果的不确定度的关系引入学生实验,要求学生根据实验所要求的测量精度对实验方案进行优化,从而将该基础性实验提升为设计性实验。
Through introducing the uncertainty of experimental result in the density measurement, the content and the method of the experiment are rewritten. Therefore, the experiment is promoted from foundational to designed.
