英文简介:Madam Curie is a French professor of physics. She was born in Poland in 1867. In 1891 she went to study in Paris University because at that time women were not admitted to universities in Poland.
When she was studying in Paris, she lived a poor life, but she worked very hard. In 1895 she married Pierre Curie, and then they worked together on the research into radioactive matter.
They discovered two kinds of radioactive matter——polonium and radium. In 1904 she and her husband were given the Nobel Prize for physics.
In 1906 Pierre died, but Marie went on working. She received a second Nobel Prize for Chemistry in 1911. So she became the first scientist in the world to win two Nobel Prizes.
汉语简介对照:居里夫人是法国物理学教授。她1867出生于波兰。1891,她去巴黎大学学习,因为当时女性没有进入波兰的大学。
当她在巴黎学习时,她过着穷苦的生活,但她工作很努力。1895,她嫁给了皮埃尔·居里,然后他们一起研究放射性物质。
他们发现了两种放射性物质——钋和镭。1904,她和丈夫获得了诺贝尔物理学奖。
1906,彼埃尔去世了,但玛丽继续工作。她于1911获得第二届诺贝尔化学奖。因此,她成为世界上第一位获得两项诺贝尔奖的科学家。

居里夫人在实验研究中,设计了一种测量仪器,不仅能测出某种物质是否存在射线,而且能测量出射线的强弱。她经过反复实验发现:铀射线的强度与物质中的含铀量成一定比例,而与铀存在的状态以及外界条件无关。
居里夫人对已知的化学元素和所有的化合物进行了全面的检查,获得了重要的发现在:一种叫做钍的元素也能自动发出看不见的射线来,这说明元素能发出射线的现象决不仅仅是铀的特性,而是有些元素的共同特性。
她把这种现象称为放射性,把有这种性质的元素叫做放射性元素。它们放出的射线就叫“放射线”。
1902年年底,居里夫人提炼出了十分之一克极纯净的氯化镭,并准确地测定了它的原子量。从此镭的存在得到了证实。
镭是一种极难得到的天然放射性物质,它的形体是有光泽的、像细盐一样的白色结晶,镭具有略带蓝色的荧光,而就是这点美丽的淡蓝色的荧光,融入了一个女子美丽的生命和不屈的信念。在光谱分析中,它与任何已知的元素的谱线都不相同。
镭虽然不是人类第一个发现的放射性元素,但却是放射性最强的元素。利用它的强大放射性,能进一步查明放射线的许多新性质。
以使许多元素得到进一步的实际应用。医学研究发现,镭射线对于各种不同的细胞和组织,作用大不相同,那些繁殖快的细胞,一经镭的照射很快都被破坏了。这个发现使镭成为治疗癌症的有力手段。
癌瘤是由繁殖异常迅速的细胞组成的,镭射线对于它的破坏远比周围健康组织的破坏作用大的多。这种新的治疗方法很快在世界各国发展起来。
在法兰西共和国,镭疗术被称为居里疗法。镭的发现从根本上改变了物理学的基本原理,对于促进科学理论的发展和在实际中的应用,都有十分重要的意义。

居里夫人有梦想,使她发现了镭,但她放弃了荣华富贵,因为她的梦想还没有真正的实现,她有一颗热爱科学造福全人类的善心为她的最初的梦想而奋斗。诺贝尔有梦想。他看见开山时工人的辛劳,决心要发明出一种工具,可以开山的工具—炸药,他为他的梦想而献身,尽管这使他失去了亲人但是没有什么能阻挡他对他的梦想的追逐。伽利略有梦想,揭开自然的面纱,向世人展示自然的规律。虽然一路上受到教堂的阻挠和迫害,但是他也没有向命运低头,因为他心中有梦想。

Marie Curie (1867-1934), formerly known as Mary can, Poland physicist, the first female Nobel prize. Marie Curie was born in Warsaw Poland, a home teacher. 10-year-old mother, family poverty, to create her hard, and diligence quality. In 1891, she went to Paris, France, University College of Science postgraduate study. Value during her arduous and "perfect" time, diligent efforts, in 1893 received a master's degree in physics, in 1894 received a master's degree in math. Almost at the same time, the fate of science and Pierre Curie, she was attracted to join. In 1895 the two married. In 1897, Marie Curie to see kellerradioactive uranium found in the report has aroused great interest in her. Her careful exploration and repeated experiments, and work closely with Mr. Curie has finally come up with two new chemical elements, which is more than the radioactive uranium. One is the "polonium", it is out of Marie Curie's love of homeland to Poland's first letter naming; another are "compact", which have devoted enormous effort Curie and his wife, wisdom, physical, and even the lives of . In order to confirm the existence of radium, they do not avoid a summer heat and winter cold does not avoid engaging in dilapidated shacks add coolies from mental labor, from 1898 to 1902 for four years time, perseverance, and finally from the dozens of tons of Asphalt uranium mining waste residue to extract one-tenth of a gram of pure radium salts, and determined the atomic weight of radium.
