1·Heavy water is heavy because the hydrogen in it weighs twice as much as ordinary hydrogen (it has a proton and a neutron in its nucleus, instead of just a proton).

重水之所以重是因为水中氢的重量是普通氢的两倍（它的原子核中有一个质子和一个中子，而不仅仅是一个质子）。

2·The working curves of heavy water and light water are comparable.

比较了重水和轻水的工作曲线。

3·PCB industry is heavy water consumption and heavy pollution industry.

PC B工业是用水大户，也是污染环境大户。

4·Lubricating grease: General grease or heavy water grease used for pump.

润滑脂：普通润滑脂或泵用重水润滑脂。

5·Sick of holding your heavy water bottle while you go on hikes in the desert?

你是否已经厌倦了在沙漠远足时带着沉重的水壶？

6·This heavy water sinks and is found in the deeper portions of the oceans of the world.

这些大密度的海水下沉，可以在世界海洋的深水域发现。

7·Meanwhile in May 2009, the Chalk River reactor started leaking heavy water and was again shut down.

也是在2009年5月，乔克里弗反应堆开始出现重水泄露现象，被迫再次关闭。

8·Deuterium generating by heavy water electrolysis is one of the most important generating deuterium methods.

电解重水制氘是生产高纯氘的重要方法之一。

9·The getter was chosen to remove N2 in D2 which was prepared by electrolyzing heavy water in high temperature.

电解重水制备d 2中常含有微量杂质n2，为降低N2含量，选择锆铁钛吸气剂高温对n 2进行脱除。

10·In this work, a tight pitch lattice and mixed fuel assemblies pressured heavy water reactor concept was investigated.
