化学实验在化学专业中是一门占比重很大的学科。对于化学专业的学生来说，学习成绩在很大程度上取决于实验课成绩的好坏。但在实验教学中，经常发现～些学生实验意识不强实验准备不充分。这必然严重影响实验的进行，破坏实验秩序。因此培养学生良好的实验习惯是学好化学课的重 Chemistry experiments in chemistry is a large proportion of subjects. For chemistry majors, academic achievement depends largely on the quality of the experimental class. However, in experimental teaching, it is often found that some students are not well prepared for experimental experimentation. This will inevitably seriously affect the experiment, undermine the experimental order. Therefore, training students to good experimental habits is to learn the heavy chemical lesson
