研究了在色谱数据处理器ＣＲ－３Ａ上进行一元，二元线性回归数据处理的ＢＡＳＩＣ程序设计．该程序能处理色谱定量过程中标准校正曲线的一元线性回归，绘制标准工作曲线拟合图，并给出线性方程和相关系数．也能处理象保留规律方程；ＬｎＫ′＝ａ＋ｂＬｎＶ＋ＣＶ及范迪姆特方程：Ｈ＝Ａ＋Ｂ／Ｕ＋ＣＵ等二元线性回归数据处理，扩展了ＣＲ—３Ａ数据处理器的处理功能． The BASIC program design for the linear and linear regression data processing on the CR-3A chromatographic data processor was studied. The program can handle the first-order linear regression of the standard calibration curve during chromatographic quantification, draw a standard working curve fit graph, and give linear equations and correlation coefficients. But also can deal with binary linear regression data processing such as LnK ’= a + bLnV + CV and Van Dijk equation: H = A + B / U + CU, which extends the processing function of CR-3A data processor.
