作者曾在“物理实验”一九八二年度第一期介绍过关于“用迈克尔逊干涉仪测波长实验的改进”情况。为进一步提高实验水平,开拓微机在物理实验中的应用。最近,我们又把单板机用于该实验过程。在对两种待测数据连续采集10次后,根据误差理论,由单板机自动进行 The author introduced the “Improvement of Wavelength Experiment with Michelson Interferometer” in “Physics Experiment”, the first issue of 1982. In order to further improve the experimental level, explore the application of microcomputer in physics experiment. Recently, we put the single-board machine for the experiment. After the two kinds of data to be measured continuously collected 10 times, according to the error theory, by the single-board machine automatically
