现在，在离贝克勒尔的发现仅15年之后，我们面前出现了一个充满新现象的世界。

Some 15 years ago the radiation of uranium was discovered by Henri Becquerel, and two years later the study of this phenomenon was extended to other substances, first by me, and then by Pierre Curie and myself.

大约十五年前铀的辐射由亨利·贝克勒尔发现，两年以后，对这一现象的研究首先由我，然后由皮埃尔·居里和我自己扩展到了对其他物质的研究。

And now, only 15 years after Becquerel's discovery, we are face to face with a whole world of new phenomena belonging to a field which, despite its close connexion with the fields of physics and chemistry, is particularly well-defined.

现在，在离贝克勒尔的发现仅15年之后，我们面前出现了一个充满新现象的世界。这些新现象属于一个领域，尽管这个领域与物理领域和化学领域密切相关，但很明显这是一个特别的领域。

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.

我想在这里回顾一下放射性研究的非同一般的发展情况；这一新兴学科起源于三十多年前贝克勒尔和居里夫妇的研究工作。

In 1896, the French physicist Becquerel Republic issued a report on the work of a detailed description of the many experiments he found that uranium, uranium and its compounds have a special ability, it can automatically and continuously release of a person's invisible rays, which rays of light and general different, so that through the photographic film and photographic paper, Roentgen discovered with also different, in the absence of high-vacuum gas discharge and high voltage plus the conditions, able to uranium and uranium from automatic salt.

1896年，法兰西共和国物理学家贝克勒尔发表了一篇工作报告，详细地介绍了他通过多次实验发现的铀元素，铀及其化合物具有一种特殊的本领，它能自动地、连续地放出一种人的肉眼看不见的射线，这种射线和一般光线不同，能透过黑纸使照相底片感光，它同伦琴发现的伦琴射线也不同，在没有高真空气体放电和外加高电压的条件下，却能从铀和铀盐中自动发生。

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.

而有些发现是在偶然间发生的：在铀被发现后，放射学已经出现世纪有余；亨利·贝克勒尔使用铀盐和照相板做同样的试验的时候发现两者可以雾化在一起，于是铀出现了。

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.

放射性是铀发现一百年之后才被贝克勒尔发现，他在同一个试验中使用了铀盐和显像版，结果发现前者是后者变得模糊。
