一、编写程序，模拟化学过程我们把模拟化学过程分成两类：一是化学过程。教师在描述化学过程时，虽然可做到生动形象，有时又用恰如其分的比喻，但还是很难让学生建立化学微观过程的图象。例如：学生学习初中化学“原子”一节，重难点是让学生建立“在化学变化中，分子可分， First, write the program, simulate the chemical process We divide the analog chemical process into two categories: First, the chemical process. While teachers describe the chemical process, although they can be vivid and sometimes use appropriate metaphors, it is still difficult for students to create images of chemical microscopic processes. For example, if students are studying the “atom” section of chemistry in junior high school, the difficulty is to allow students to establish that "in the course of chemical changes, the molecules can be separated,
