分析误差的定性研究

误差是定量分析的关键问题，是用来衡量分析结果准确度大小的。在定量分析过程中，有时并不需要算出误差的大小，而只需对误差的大小、正负作一下判断，对误差做出定性研究即可，以其校正方法，使定量分析的结果更准确。

On the Qualitative Research of Analytical Error

Errors and residuals is the key to the question in quantitative analysis which also measure and analysis the accuracy of the result. We needn＇ t figure out the size of the error but just judge the size and plus - minus of the error in the process of the quantitative analysis. In order to make the result of the qualitative research more exactly, we can do some qualitative research about the error to correct the research method.
