初中物理第二册关于热辐射的演示实验中,是让太阳光照射黑色或白色的烧瓶,装置虽简单,却要受天气的影响,且不够直观。纵观几种物理刊物已发表的有关热辐射实验的文章,所述的实验方法也或多或少存在实验不够直观,或装置较复杂的缺点。 In the demonstration of heat radiation in the junior high school physics book 2, it is to let the sunlight shine on the black or white flask. Although the device is simple, it must be affected by the weather and not intuitive enough. A review of published articles on thermal radiation experiments in several physics publications shows that the experimental methods are more or less flawed by experiments that are not intuitive or that the devices are more complex.
