化学研究的对象是物质的组成、结构、性质以及变化规律。物质的变化既包括形态、颜色改变等宏观现象 ,又包括大量的微观变化。学生在学习过程中 ,往往要通过书本的描述 ,教师的讲解去想象实际发生在三维空间中的运动和变化过程 ,这种从静态到动态 ,从文字、语言到具体图像的转 The object of chemical research is the composition, structure, properties, and laws of change. Substance changes include both macroscopic phenomena such as changes in form and color, as well as a large number of microscopic changes. During the learning process, the students often go through the description of the book and the teacher’s explanation to imagine the movement and change process that actually takes place in the three-dimensional space.
