关于化学分析教学实验中平行测定份数的探讨

Discussion about Parallel Determining Number in Teaching Experiment of Chemical Analysis

在化学分析教学实验中平等测定份数与合理判断学生实验是否需要重做,如何检验测定结果的限差和划定置信区间等问题,本文拟从重复次数、选择次数,划定区间等方面展开讨论。

In teaching experiment of chemical analysis, there are some problems on parallel determining number, on reasonable judgment on whether students＇ experiment should be done again, on how to examine the restricted error of measured result and how to ascertain the confidence interval. The discussion will be taken from repeated times, chosen times and ascertained interval.
