In this contribution, the various and fundamentally different uses and applications of isotope signatures (of both heavy and light elements) are discussed. Examples are given for the successful use of 87Sr/86Sr in uncovering fraud in wine trade. Also, in an experiment related to "Waldsterben",...
汉语翻译n. 丰富, 充足, 大量 【经】 丰富, 充裕 相关词组:have an abundance of in abundance英语解释：名词 abundance:the property of a more than adequate quantity or supply 同义词：copiousness, teemingness (physics) the ratio of the number of atoms of a specific isotope of an elem...
Stable isotopes of carbon, hydrogen, nitrogen, oxygen and sulfur are widespread in nature. Nevertheless, their relative abundance is not the same everywhere. This is due to kinetic isotope effects in enzymes and other physical principles such as equilibr
51 The low natural abundance of this isotope (0.0156%) means that NMR studies are generally restricted to synthetic materials that have been isotopically enriched in 2H. However, starting materials enriched in 2H are relatively cheap compared to those enriched in isotopes of other elements, and so...

(physics) the ratio of the number of atoms of a specific isotope of an element to the total number of isotopes present the property of a more than adequate quantity or supply 例句 They needed to learn the lesson of abundance.Then the stock market crashed in 1987, and Alan and Linda lost...
b.The condition of being in rich supply:bananas growing in abundance. 2. a.Degree of plentifulness:"Species of low abundance are ignored in the calculation of predominance"(William M. Lewis). b.ChemistryThe amount of an isotope of an element that exists in nature, usually expressed as a ...
Percent abundance describes the prevalence of each of an element’s isotopes in nature.The percent abundance of each isotope is used in the calculation of an element’s average atomic mass. Many elements exist as two or more isotopes, which are versions of the same element that possess the sa...
Science Chemistry Isotope What is relative abundance of isotopes?Question:What is relative abundance of isotopes?Isotopes:An element is a type of atom. The characteristics of each type of atom or its identity is determined by the number of protons in the nucleus of the atom. So this number ...
