| 词汇 | stoichiometry |
| 释义 | stoichiometry noun[ U ] chemistry specializeduk /ˌstɔɪ.kiˈɒm.ə.tri/ us /ˌstɔɪ.kiˈɑː.mə.tri/ (the study of) the relationship between the quantities of substances involved in a chemical reaction and the substances that are produced as a result of that chemical reaction: 化学计量学;化学计量法 Stoichiometry is of fundamental importance in modern chemistry.化学计量学在现代化学中具有根本的重要性。 We can find the stoichiometry of a reaction if we know the amounts of each reactant that react together and the amounts of each product formed.如果我们知道每个反应物在一起反应的量，以及每个产物形成的量，我们就可以找到反应的化学计量法。 In the chemical industry, a knowledge of stoichiometry is essential for the calculation of the yields of chemical products. Stoichiometry is the calculation of relative quantities of reagents and their end-products in a chemical reaction. The stoichiometry of the equation is 1 : 3 : 2 : 3. Chemistry - general words acceptor aerosol aerosolize allotrope amphiprotic balanced equation chemical equation electrolyte endocrine disruptor endothermic epitaxial epitaxially epitaxy inorganic chemistry ionic bond nonchemical nonelectrolyte nonreactive preatomic reactive Examples of stoichiometrystoichiometry The stoichiometry of the exact reaction will depend on the nature of the organic matter involved, here assumed to be saturated aliphatic hydrocarbon. Assembly of the inhibitory glycine receptor: identification of amino acid sequence motifs governing subunit stoichiometry. Here, the stoichiometry of chemical complexation and physical formulation may affect cellular uptake. This is obviously a question where ecological stoichiometry has direct relevance and there is a large oceanographic literature related to these issues. The framework of biological stoichiometry may serve as one medium for such interdisciplinary cross-talk. I will argue that biological stoichiometry offers considerable promise to help produce a more coherent picture in the rapidly evolving world of astrobiology. With respect to proto-biological ecosystems, everything is stoichiometry ! Biological stoichiometry extends this mode of thinking to all types of biological systems. Intermediates in the chaperonin-assisted refolding of rhodanese are trapped at low temperature and show a small stoichiometry. During the past decade ecological stoichiometry has shed considerable light on the ways that food webs function in the modern world. One is that control of connexin stoichiometry\\ arrangement can not only determine whether cyclic nucleotides can pass from cell to cell, but which one. Two primary ideas have emerged from recent studies of ecological stoichiometry that have important implications for food-web ecology. It was found that the model agreed with the numerical calculations to within 40%, for a number of fuel-oxidizer mixtures over a wide range of stoichiometries. Upon polymerization of - and -tubulin isotype 2 into microtubules the stoichiometry of binding increased to 2 : 1 (mebendazole : tubulin) while binding affinity remained the same. The efficiency of drug loading and uptake per cell-binding event is comparatively lower in these types of simple conjugates as the stoichiometry of ligand to drug is 1:1.
