沥青铀矿

After four years' hard work and refinement of tons of pitchblende, Marie and her hus-band at last saw the dim blue light of the new element -- radium.

经过四年的艰苦工作，提炼了成吨的沥青铀矿，玛丽和她的丈夫终于看到了新元素——铀发出的微弱的蓝光。

The method for pitchblende synthesis in temperature range of 17 to 115℃ and its identification are described.

本文介绍了17—115℃沥青铀矿合成的方法及对产品的鉴定结果。

In 1898, Marie found a new element in the pitchblende.

居里，一位著名的科学家，就是一个很好的例子。1898年，玛丽在沥青铀矿中发现了一种新元素。

It is shown that microbial pitchblende quickly formed on the surface of the bacteria a week later.

结果表明，实验一周后，微生物成因沥青铀矿迅速地在该菌胞表面生成。

A method is described for the separation of high purity 230Th from pitchblende based on ion exchange.

本文以阴离子和阳离子交换法从沥青铀矿中提取~(230)Th。

Marie Curie, a famous scientist, has set a good example. In 1898, Marie found a new element in the pitchblende.

玛丽。居里，一位著名的科学家，就是一个很好的例子。1898年，玛丽在沥青铀矿中发现了一种新元素。

In reality the proportion of the hypothetical element was far lower and it took several years to show unequivocally that ''.'pitchblende'.

实际上这种假设中的元素的浓度要小得多，我们花了几年时间才明确无误地证明沥青铀矿物质中至少含有一种高放射性物质，在化学意义上这就是一种新元素。

In reality the proportion of the hypothetical element was far lower and it took several years to show unequivocally that pitchblende contains at least one highly-radioactive material which is a new element in the sense that chemistry attaches to the term.

实际上这种假设中的元素的浓度要小得多，我们花了几年时间才明确无误地证明沥青铀矿物质中至少含有一种高放射性物质，在化学意义上这就是一种新元素。

We found that pitchblende contains at least two radioactive materials, one of which, accompanying bismuth, has been given the name polonium , while the other, paired with barium, has been called radium.

我们发现沥青铀矿物中至少含有两种放射性物质：与铋伴生的命名为钋，与钡伴生的命名为镭。
