摘要
电偶极子是电学中基本的概念,它是电介质理论和原子物理学的重要模型。随着电偶极子研究的不断深入,电偶极子模型的应用使很多理论有了更加科学合理的解释。特别是电偶极子在生物大分子中化学键的形成,维持DNA分子稳定的双螺旋结构,刺激改变蛋白质的结构和功能,决定物质的可溶性以及在心脏电活动等生命活动领域均起到重要的作用。为了更深入具体地了解电偶极子的作用,本文将对以上几个方面做以详细介绍。
The electric dipole is a basic concept in electricity.It is an important model of dielectric theory and atomic physics.With the deepening of the research of electro-dipole,the application of electro-dipole model makes many theories more scientific and reasonable.In particular,electro-dipole plays an important role in the formation of chemical bonds in biological macromolecules,maintaining ingenuity structure of DNA molecules,stimulating to change the structure and function of protein,determining the solubility of substances and cardiac electrical activity and other areas of life activities.In order to understand the role of the electro-dipole better,this paper gives the details of the above aspects.
