X线(俗称X光)在医疗工作中佔很重要的地位,許多疾病的診断和治疗都需要它、过去,必須从国外購买X线机器;解放以来,由于劳动人民的积極努力,及人民政府的大力支持,自制的机器,已經开始供应。所以全国各地的医疗单位中,X綫的設备已大大的普遍了,为了使讀者对它有一概念,簡單的介紹如下: 一、X射綫的發現:1895年11月8日,物理学家伦琴(W.K.Routgen)在研究低压放电时,發现放置在附近的铂氰化鋇结晶体發出一种螢光。当时,他虽將实驗室遮盖得漆黑,不通一点光线,可是,只要这种放电管放电,則鋇鹽依然發出螢光。因此,他想可能是由于放电管發出某种富有穿透力的光綫所引起的現象。他再进一步試驗,發現这种光綫可以穿透厚紙板和木板,並且可以穿透手掌,使骨骼的影像在螢光屏上显出。X綫就是这样發現的。当时因为不了解这种光綫的本質,伦琴就用代数学中未知数X做它的名字,后人为了纪念他的重大發現,也
X-rays, commonly known as X-rays, occupy a very important place in medical work. They need it for the diagnosis and treatment of many diseases. In the past, X-ray machines must be purchased from abroad. Since the liberation, due to the active efforts of the working people and Strong support from the people’s government, self-made machines, has begun to supply. Therefore, the medical units across the country, the X-ray equipment has been greatly universal, in order to make readers have a concept on it, a brief introduction is as follows: First, the discovery of X-ray: November 8, 1895, physicists In a study of low-voltage discharge, WK Routgen found that a barium platinide crystal placed nearby emits a fluorescent light. At that time, although he covered the laboratory dark, no light, but as long as the discharge tube discharge, the barium salt is still fluorescent. Therefore, he thought it might be due to the fact that the discharge tube emits some sort of penetrating light. He further tests and found that this light can penetrate the cardboard and wood, and can penetrate the palm of your hand, so that the skeleton’s image on the screen. X-ray is found this way. Because at that time, he did not understand the nature of this light, Roentgen algebra in the unknown X do its name, descendants in memory of his great discovery, also
