玻 -玛定律是高中二年级物理课中研究气体性质的一个重要内容 ,验证玻 -玛定律是高二物理学生实验。我市高中试用的新教材对该实验的装置和实验方法都有较大的变动。其装置如图 1所示。在实验过程中 ,许多学校的老师反映该实验常常出现较大的误差。为此 ,我们经过多次反复试验 Glass-Marine Law is an important part of studying the nature of gases in the second grade physics class in senior high school. It is verified that Glass-Marine Law is a high school physics student experiment. The new textbooks used in the trials in the high school of the city have made great changes to the experimental devices and experimental methods. Its device is shown in Figure 1. During the course of the experiment, many school teachers reported that the experiment often experienced large errors. For this purpose, we have undergone repeated trials
