高中物理下册301页介绍了伦琴射线(即X光线)的产生原理和应用。由于一般学校没有X光机,只能通过分析其基本原理和举冽米说明。学生对此的认识和理解是不够的,而且对这些内容产生神秘感。下面介绍一种简易X光机的制作,配合教学会使教学效果更好。制法:将废旧真空电灯泡(一般40W以下即可)的两个电极焊接起来,作为阴极;在对着灯丝的地方,用胶贴上一块铅箔(也可用铜片或烟盒内的锡纸)作为对阴极。这 The physics of high school physics volume 301 introduces the principle and application of X-ray ray generation. Since the general school does not have an X-ray machine, it can only explain its basic principle and give a description of glutinous rice. Students’ understanding and understanding of this is not enough, and there is a mystery to these contents. The following describes the production of a simple X-ray machine, with teaching will make teaching better. Method: Welding the two electrodes of a used vacuum bulb (generally less than 40W) as a cathode; place a piece of lead foil on the place of the filament (also copper or copper foil inside the cigarette case) As a cathode.
