摘要
就物理实验教材中有关误差理论概念的延伸、表达,以及有效数据的理解,分别进行了剖析,以便有利于学生学习和教师教学的参考。
In this paper some expressing ways and meaning extending of concept in error theory were discussed in physics experiment.The understanding on useful data were explained.For example,① the position of standard error（ε） were marked in the curve of normal distribution,② the concept of standard error were extended in discussing confidence level（P） of uncertainty degree（U）,③the curve of normal distribution of the steel plate thickness were imitated by data from measuring with screw thread mirometer.I wish that the above analysis conclusion can provide some references for students and teachers in the processes of learning and teaching of physics experiments.
