近十多年来化学学科出现了一些新的思潮和新的看法,化学在形式和内容上都有很大的改观,可以说这门学科正处在一种急剧变革的过程中。就化学的许多方面说,这种变革的主要特点有三:一是从基本上是描述性的过渡到推理性的,二是从主要是定性的过渡到定量的,三是从主要是宏观的过渡到微观的。这种发展过程本是多年来化学发展的总的趋势,是从感 In recent ten years, some new thoughts and new ideas have emerged in chemistry, and chemistry has greatly changed in form and content. It can be said that this discipline is in a process of rapid change. In many aspects of chemistry, the main features of this change are threefold: first, from a largely descriptive transition to reasoning; second, from a predominantly qualitative to a quantitative; and third, from a predominantly macro transition To microscopic This development process has always been the general trend of chemical development over the years, is from the sense
