有位科学家曾发现一种叫铀的金属能发出一种放射线,这种现象后来玛丽·居里称为故射性。但是这种放射线是从哪里来的?又是什么样子的?这正是她要去发现的一个自然秘密。她非常仔细地进行了一次又一次的实验,失败,成功,又失败,有些成功,再取得一些成功。这一切似乎证明了在她试验的矿物中存在着某种人们一无所知的放射线。玛丽曾用这样的话表达了她的思想:“生活对我们任何人来说都是不容易的。我们必须工作,而且最重要的是要有自信心。我们一定要相信我们每个人 One scientist has discovered that a metal called uranium emits a kind of radioactivity, a phenomenon that Marie Curie later referred to as “prisms.” But where does this kind of radiation come from and what does it look like? This is a natural secret she is going to discover. She did her experiments very carefully, failed, succeeded, failed, some successes, and then some successes. All this seems to prove that there is some kind of radiation unknown to people in the minerals she tested. Mary used her words to express her thoughts: "Life is not easy for any of us. We have to work, and most importantly, have confidence. We must believe that each of us
