近代电子计算机就象分析天平一样是一种实验必备工具。在定量分析实验教学中应用小型可程序电算器指导学生实验,既简便易行,而且又科学、可靠,且由于这些电算器价廉易得,其法也是易于实施的。本文拟介绍在指导学生做定量分析实验时,用CASIO FX—502P可程序电算器,按误差和数据处理理论,决定实验中平行测定的份数和绘制标准曲线两方面的问题。
Modern electronic computers, like analytical balances, are an experimental tool. The application of small programmable telegraphy to students’ experiments in quantitative analysis experiment teaching is both simple, scientific and reliable, and its method is also easy to implement due to its cheapness and affordability. This article intends to guide the students to do quantitative analysis experiments, with CASIO FX-502P programmable electronic calculator, according to the error and data processing theory, determine the experimental parallel determination of the number of copies of the standard curve and the two aspects of the problem.
