可编程序计算器处理化学实验数据已有报道,但却是脱机处理的非模拟数据。模拟数据通常用计算机通过模/数转换器联机处理。利用可编程序计算器,也可以通过模/数转换器联机处理模拟数据。本文以进口日本的热分析仪及其所带之电子数据处理系统和SX-350可编程序计算器,对热重分析(TG)曲线、示差扫描量热(DSC)曲线模拟数据进行联机处理。设计了两个程序,其处理精度为±1%左右。
Programmable calculator to deal with chemical experimental data has been reported, but it is off-line processing of non-simulated data. Analog data is usually processed online by a computer via an A / D converter. Using programmable calculators, analog data can also be processed online via an A / D converter. In this paper, thermogravimetric analysis (TG) curve and differential scanning calorimetry (DSC) curve simulation data are processed online by imported thermal analyzer in Japan and its electronic data processing system and SX-350 programmable calculator. Two programs have been designed and their processing accuracy is about ± 1%.
