分析化学中有效数字修约运算的可视化实现

The visualization of Calculation of the effective figures of Analytical Chemistry

本文从有效数字及修约规则和基本四则运算出发,采用Visible Basic 6.0编程来实现化学复杂计算中进行有效数字修约运算的可视化处理.该软件能够按照有效数字的修约规则快速准确地实现对实验量测数据进行相应的四则运算和结果修约,达到不同实验结果的准确度和相对误差要求,同时也实现了人机交互的助教助学模式.

From the figures and rounding rules for the effective and basic four calculations,it applied the computer programming language Microsoft Visible Basic 6.0 to develop for the solution of chemical calculation in accordance with certain rules related to calculating the effective number of visual processing software.The software can be effective in accordance with the rules for rounding numbers to achieve fast and accurate analysis of experimental data on the corresponding arithmetic and rounding the result,different analysis results to the accuracy and relative error requirements,but also realized the assistant human-computer interaction Student model.
