实验是研究物理学的一个重要方法，也是物理教学的重要基础。过去，虽然我们在主观上也很重视实验教学，但对于教学中的某些根本性的问题却缺乏认真的钻研和探索，致使实验教学存在着一些问题。具体表现为：１、没有充分认识到实验教学的重要意义，对一些比较复杂的演示实验， Experiments are an important method for studying physics and are also an important basis for physics teaching. In the past, although we have also attached great importance to experimental teaching subjectively, we have failed to seriously study and explore certain fundamental problems in teaching, resulting in some problems in experimental teaching. The specific performance is as follows: 1. The importance of experimental teaching is not fully recognized. For some of the more complex demonstration experiments,
