中文摘要：

氢键是分子内或分子间存在的一种相互吸引作用,对物质的性质有很大影响,仍然是生物、化学、材料等学科研究的热门领域之一。2011年,IUPAC对氢键已给出了最新的定义。文章在回顾了氢键定义研究历史的基础上,对比分析现代大学教材中氢键的定义,说明现代大学教材中氢键的定义已不能准确定义氢键,建议使用2011年IUPAC给出的最新氢键定义。

英文摘要：

Hydrogen bond is an attractive interaction between intramolecular or intermolecular and has a strong impact on the natures of substance.The importance of hydrogen bonding is amply demonstrated by the number of publications in chemistry,biology and materials science et al.In 2011,the International Union of Pure and Applied Chemistry（IUPAC） proposed a modern definition for the hydrogen bond.The paper stated the history of the definition hydrogen bond,and analyzed and compared the different definitions in different college textbooks in our country.It was found that the definitions of hydrogen bond in textbooks of modern colleges may be termed outdated,too narrow,or arguably even erroneous.So,we gave a suggestion that we should use the newest definition of hydrogen bond which comes from IUPAC in 2011.
