众所周知,分析化学实验老师要正确地考察、评定一个学生的实验成绩是一项相当冗长繁重的工作。现在,我们应用微型计算机代替简单计算器的手工计算,处理实验数据,使这一问题基本得到解决。具体做法是:根据定量化学分析实验内容和每个实验的具体要求,如实验数据,标准溶液每份测定值,平均值,相对偏差(或绝对偏差);样品每份测定值,平均值,相对偏差
As we all know, analytical chemistry experiment teacher to correctly examine and assess a student’s test scores is a very lengthy and arduous work. Now, we use the microcomputer instead of simple calculator manual calculation, processing experimental data, so that this problem is basically solved. The specific practices are: According to the quantitative chemical analysis of the contents of the experiment and the specific requirements of each experiment, such as experimental data, the standard solution of each measured value, average, relative deviation (or absolute deviation); sample each measured value, average, relative deviation
