摘要:

分析化学简答题是分析化学习题和考试中常用的考查形式。传统的做法更多是采用文字表述的方式进行解题,而文字的叙述其实并不清晰,容易产生歧义。本文介绍基于“量”的观念,采用严格的数学分析的方法来解答分析化学的简答题,使得解答过程更为严谨,更易于理解。

Abstract:

Short answer questions are commonly seen in exercises and examinations in analytical chemistry. The usual way to solve this type of question is by expressing the argument verbally, which can lead to a lack in clarity and can easily generate ambiguity. In this paper, a method for solving this type of question using mathematical analysis based on the perception of quantity is shown. This will make the solution more rigorous and easier to understand.

Key words: Short answer questions, Perception of quantity, Analytical chemistry
