伦琴的英文简介

伦琴是照射量单位，1伦琴相当于在1立方厘米标准状况的空气（质量为0.001293克）中，产生的正、负离子电荷各为1静电单位。

伦琴的英文代号为R，其定义是在0摄氏度，760毫米汞柱气压的1立方厘米空气中，造成1静电单位（3.3364×10?10库仑）正负离子的辐射强度=1伦琴单位。

伦琴单位不是国际单位，但在医学等领域还是很常用的，与国际单位的换算是1伦琴单位=2.58×10-4库仑/千克。

照射量，表示射线空间分布的辐射剂量，即在离放射源一定距离的物质，受照射线的多少，以X线或Y线在空气中全部停留下来所产生的电荷量来表示。

需要注意的是，照射量只用于光子在空气中引起电离的情况，其他类型的辐射，虽然也可以在空气中引起电离，却不允许使用照射量。

伦琴射线的由来，和一位德国著名物理学家息息相关，他最大的成就就是发现了X射线，为开创医疗影像技术铺平了道路，对医学界可以说是一项创举，所以在1901年，他被授予了诺贝尔物理学奖，这项发明还影响了很多其他的重要领域。

到今天，为了纪念这位德国著名物理学家的成就，X射线以他的名字命名，在许多国家被称为伦琴射线，另外第111号化学元素Rg，也用伦琴的名字命了名。

英语mr怎么读

During 1895 R?ntgen was investigating the external effects from the various types of vacuum tube equipment — apparatus from Heinrich Hertz, Johann Hittorf, William Crookes, Nikola Tesla and Philipp von Lenard — when an electrical discharge is passed through them. In early November he was repeating an experiment with one of Lenard's tubes in which a thin aluminium window had been added to permit the cathode rays to exit the tube but a cardboard covering was added to protect the aluminium from damage by the strong electrostatic field that is necessary to produce the cathode rays. He knew the cardboard covering prevented light from escaping, yet R?ntgen observed that the invisible cathode rays caused a fluorescent effect on a small cardboard screen painted with barium platinocyanide when it was placed close to the aluminium window. It occurred to R?ntgen that the Hittorf-Crookes tube, which had a much thicker glass wall than the Lenard tube, might also cause this fluorescent effect.

In the late afternoon of 8 November 1895, R?ntgen determined to test his idea. He carefully constructed a black cardboard covering similar to the one he had used on the Lenard tube. He covered the Hittorf-Crookes tube with the cardboard and attached electrodes to a Ruhmkorff coil to generate an electrostatic charge. Before setting up the barium platinocyanide screen to test his idea, R?ntgen darkened the room to test the opacity of his cardboard cover. As he passed the Ruhmkorff coil charge through the tube, he determined that the cover was light-tight and turned to prepare the next step of the experiment. It was at this point that R?ntgen noticed a faint shimmering from a bench a meter away from the tube. To be sure, he tried several more discharges and saw the same shimmering each time. Striking a match, he discovered the shimmering had come from the location of the barium platinocyanide screen he had been intending to use next.

R?ntgen speculated that a new kind of ray might be responsible. 8 November was a Friday, so he took advantage of the weekend to repeat his experiments and make his first notes. In the following weeks he ate and slept in his laboratory as he investigated many properties of the new rays he temporarily termed X-rays, using the mathematical designation for something unknown. Although the new rays would eventually come to bear his name in many languages where they became known as R?ntgen Rays, he always preferred the term X-rays. Nearly two weeks after his discovery, he took the very first picture using x-rays of his wife's hand, Anna Bertha. When she saw her skeleton she exclaimed "I have seen my death!"

The idea that R?ntgen happened to notice the barium platinocyanide screen misrepresents his investigative powers; he had planned to use the screen in the next step of his experiment and would therefore have made the discovery a few moments later.[vague]

At one point while he was investigating the ability of various materials to stop the rays, R?ntgen brought a small piece of lead into position while a discharge was occurring. R?ntgen thus saw the first radiographic image, his own flickering ghostly skeleton on the barium platinocyanide screen. He later reported that it was at this point that he determined to continue his experiments in secrecy, because he feared for his professional reputation if his observations were in error.

R?ntgen's original paper, "On A New Kind Of Rays" (?ber eine neue Art von Strahlen), was published 50 days later on 28 December 1895. On 5 January 1896, an Austrian newspaper reported R?ntgen's discovery of a new type of radiation. R?ntgen was awarded an honorary Doctor of Medicine degree from the University of Würzburg after his discovery. He published a total of three papers on X-rays between 1895 and 1897. Today, R?ntgen is considered the father of diagnostic radiology, the medical specialty which uses imaging to diagnose disease.
