分析测试中若有系统误差,则因其产生的原因一定,且各平行测试中的误差方向相同,大小一致,不能指望通过增加测定次数来发现和消除它。因此,系统误差是影响分析结果准确度的主要因素。一些文献虽然指出了判断分 If there is any systematic error in the analysis and testing, the reason for its occurrence is certain, and the error directions in each parallel test are the same and have the same size. It can not be expected to find and eliminate it by increasing the number of measurements. Therefore, the systematic error is the main factor affecting the accuracy of the analysis results. Although some documents point out the judgment
