一种新型线性质量控制图及其在食品检验中应用

A New Linear Quality Control Chart and its Application in Food Inspection

为了克服现行质量控制图存在的不足,提高质量控制的效果,作者利用直线回归方程剩余标准差的原理绘制一种新型线性质量控制图。实践表明这种质量控制图比以往的质控图更可靠和简便。

This paper reported a new linear quality chart according to standard deviation of Y for fixed X of linear regression. It overcame the shortcoming of the former uaed quality conrtol chart and improved the result of the quality control chart.
