化学计算过程，主要是一个化学问题的数学处理过程，即对物质的组成、结构、性质和变化规律的量化过程。不同的问题，需要不同层次的解题能力。各层次能力的形成，知识点及基本解法的训练固然很重要，但在解答具体问题时，具备下列几种思维意识，也是非常重要的。笔者在教学中 The chemical calculation process is mainly a mathematical process of chemical problems, that is, the quantification of the composition, structure, properties, and change laws of matter. Different issues require different levels of problem solving skills. The formation of various levels of competence, the training of knowledge points and basic solutions is of course very important, but it is also very important to have the following types of thinking in answering specific questions.
