stoichiometry
noun [ U ] chemistry specialized uk/ˌstɔɪ.kiˈɒm.ə.tri/ us/ˌstɔɪ.kiˈɑː.mə.tri/
化学计量学;化学计量法
(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
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。
