高中物理教材中,对气体性质定律的验证是教学重点,也是难点。长期以来,我国各校使用的两种装置,在实践过程中,其漏气现象不同程度的存在,而且都随着使用次数的增多而加剧,它使被研究的气体形成了一个变量,违背 In high school physics textbooks, verification of the laws of gas properties is a key and difficult task in teaching. For a long time, the leakage of the two devices used by schools in our country in various stages has existed in different degrees, and they have been exacerbated with the increase in the number of uses. It has caused the studied gas to form a variable and violated it.
