比色分析是分析化学中重要分析方法之一,在工农业生产和科研中应用广泛。在比色计的使用过程中,绘制标准曲线、查曲线、计算结果繁琐而费时,本文介绍一种用一可编程序计算器实现其浓度直读或分析结果直读,省时而省力。所用的计算器除具有一般函数计算器的性能外,还应具有线性回归性能和代数式存储性能。这里我们使用日本SHARP公司产的EL-5103S袖珍计算器,而国产计算器DS-
Colorimetric analysis is one of the important analytical methods in analytical chemistry. It is widely used in industrial and agricultural production and research. In the use of the colorimeter, draw the standard curve, check the curve, the calculation results cumbersome and time-consuming, this article describes a program with a programmable calculator to achieve direct reading or analysis of direct reading results, saving time and effort. The calculator used should have linear regression performance and algebraic storage performance in addition to the performance of the general function calculator. Here we use the Japanese company SHARP EL-5103S pocket calculator, while the domestic calculator DS-
