摘要： 学术界在表述环加成反应时，(m + n + …)和[m + n + …]环加成混用，不利于准确的学术交流。本文介绍了国际纯粹与应用化学联合会(IUPAC)规定的两种环加成反应表述方式，指明了它们的准确含义和使用环境。

Abstract: The two systems of notations for cycloaddition reactions, namely (m + n + …) or [m + n + …], are misused in academic publications. This paper introduces the accurate IUPAC (International Union of Pure and Applied Chemistry) definitions of the two systems of notations, and points out the guidelines for accurately using the two systems for describing a cycloaddition reaction.

Key words: Organic chemistry, Cycloaddition reaction, Number of atoms, Number of electrons, Higher-order cycloaddition
