Примеры употребления для isotopic
1. U.S. scientists familiar with the results of the isotopic analysis of the seized material, carried out by the U.S.
2. Alexander Koldobsky, a nuclear materials expert at the Moscow Engineering Physics Institute, said Thursday that an isotopic analysis of highly enriched uranium would not specify where the material had been enriched.
3. Such "dual use" equipment included global–positioning system equipment, computers and computer accessories, and a device known as a mass spectrometer, used to determine the isotopic composition of elements.
4. In particular, researchers are eager to know whether the isotopic makeup of the water in the air is the same as the water in the soil, but they have not been able to load the proper material to find out.
5. The Vostok core, which is now stored in pieces in Denver, Grenoble and on Antarctica, contains a continuous climate record stretching back four full glacial cycles. (As is the case with Greenland cores, temperatures can be ascertained by measuring the isotopic composition of the ice, and the make–up of the atmosphere determined by analysing tiny bubbles of trapped air.) What the Vostok record shows is that the planet is already nearly as warm as it has been at any point in the last 420,000 years.
