After that, the Joliot- Curie couple drew a lesson and through the experiment they found the artificial radioactivity and achieved the Nobel Prize of chemistry.

此后搜锁一个能看的毛片网站，約里奧-居里夫婦吸取了教訓(xùn)，經(jīng)過(guò)實(shí)驗(yàn)最終發(fā)現(xiàn)了人工放射性現(xiàn)象4455vw在线视频，由此獲得諾貝爾化學(xué)獎(jiǎng)黄网站在线观看视频免费。

"Fermi:Italian-born american physicist. He won a 1938 Nobel Prize for his work on artificial radioactivity caused by neutron bombardment . In 1942 he produced the first controlled nuclear chain reaction, in a squash court at the University of Chicago."

"費(fèi)密：意大利裔的美國(guó)物理學(xué)家中国野外性农村xXxXHD，因研究中子人工引發(fā)原子衰變而獲1938年諾貝爾獎(jiǎng)，1942年他在芝加哥大學(xué)擁擠的球場(chǎng)上第一次實(shí)現(xiàn)了受控鍵式核反應(yīng)久久国产精品激情视频。"

There was great radioactivity and nuclear action, and much of Earth was rent asunder.

有非常多的放射能與核能日韩无码国产精品视频，地球的大部分變得分裂。

In fact, it was Curie that coined the term radioactivity, though Henri Becquerel discovered the phenomenon years earlier.

事實(shí)上国产精品不卡在线观看，是居里創(chuàng)造了放射這個(gè)術(shù)語(yǔ)精品无码视频在线观看，盡管貝可勒耳更早發(fā)現(xiàn)了這個(gè)現(xiàn)象。

Usually 1896 Becquerel discovered natural radioactivity as the beginning of nuclear physics, the next 40 years, it is mainly engaged in the nature of radioactive decay and radiation research.

通常把1896年貝克勒耳發(fā)現(xiàn)天然放射性做為核物理的開(kāi)端好看的久久黄网站，此后的40多年国产无套粉嫩白浆在线观看麻豆，人們主要從事放射性衰變和射線性質(zhì)的研究。

I would like here to recall the extraordinary development of radioactivity, this new science which had its origin, less then forty years ago in the work of Henri Becquerel and of Pierre and Marie Curie.

我想在這里回顧一下放射性研究的非同一般的發(fā)展情況色库视频91；這一新興學(xué)科起源于三十多年前貝克勒爾和居里夫婦的研究工作欧美伦。

The phenomenon was first reported in 1896 by Henri Becquerel for a uranium salt, and it was soon found that all uranium compounds are radioactive due to the uranium's radioactivity.

放射性：某些類的物質(zhì)自發(fā)發(fā)射輻射的特性。1896年貝克勒耳第一個(gè)報(bào)告在鈾鹽中發(fā)現(xiàn)了這一現(xiàn)象亚洲伊人成无码91，不久發(fā)現(xiàn)由于鈾有放射性国产免费三级片视频，所以所有的鈾化合物都是放射性的。

Radioactivity came to light a century after the discovery of uranium when Henri Becquerel used

The Curies and Henri Becquerel shared the Nobel Prize for Physics because of their discovery of natural radioactivity.

居里夫婦和昂利·貝克雷爾（1852-1908，法國(guó)物理學(xué)家中文字幕在线观看公司，1903年諾貝爾獎(jiǎng)金獲得者美女色色色网站。譯者注）因他們共同發(fā)現(xiàn)天然物質(zhì)的放射性而共享了1903年的諾貝爾獎(jiǎng)。

And some discoveries happen by accident. Radioactivity came to light a century after the discovery of uranium when Henri Becquerel used uranium salts and photographic plates in the same experiment and found that one fogged the other.

而有些發(fā)現(xiàn)是在偶然間發(fā)生的：在鈾被發(fā)現(xiàn)后中国农村妇女HDⅩXX，放射學(xué)已經(jīng)出現(xiàn)世紀(jì)有余日本大片黄色；亨利·貝克勒爾使用鈾鹽和照相板做同樣的試驗(yàn)的時(shí)候發(fā)現(xiàn)兩者可以霧化在一起，于是鈾出現(xiàn)了国内机关自拍视频在线观看。
