为发挥纸层析和薄层层析的简便,快速的特点,提高其效能。本文用BASIC语言编制了纸层析、薄层层析系统的评价和系统最佳组合选取的程序包(已在TRS-80机上通过)。其中包括:层析系统的信息量计算,数值分类一信息量选取法,系统差值信息量分类法,类平 To make use of the simple and rapid features of paper chromatography and thin layer chromatography, improve its performance. This paper uses BASIC language to compile the package of paper tomography, thin-layer tomography system evaluation and optimal combination of system selection (passed on TRS-80 machine). Including: the amount of information in the chromatography system, numerical classification and information selection method, systematic difference information classification method, similarity
