Thus, more of the heavyisotope is left behind in the ocean and absorbed by marine organisms.
因此,更多的重氧同位素留在了海洋里,并被海洋有机物吸收。

This is the DEUT ERIUM PLANT, an automated facility for extracting the heavyisotope of hydrogen from the local water supply.
实际上这是个加工厂一个全自动化的设施通过来从当地水源中提取氢气的重同位素来生产氘气。

Scientists say the excess heavy nitrogen could have come from a comet. And the heavier oxygen from a natural process that left more of the light isotope in the part of the nebula that made the sun.
