晶体化学中的键电荷模型及其应用前景

Prospecting of Bond-Valence Model and Its Applicstion in Crystal Chemistry

键电荷模型将晶体中原子的有效电荷与键长有机地联系起来，从而提供了一种揭示分子晶体结构和电子结构相关关系的方法．键电荷模型的建立被看作是当今无机固体化学的一个重大进展，它具有简洁性、可靠性和实用性的特点．对于晶体中原子的电荷分布，结构畸变的研究和键长的确定有独特之处．值得研究和发展．本文简述了这一模型的基本原理及其应用前景．同时做出了简单的评价．

A good method for crystal structure and eletronic structure study is provided by Bond-Valence model which correlates the arendc absence and bond length. The Bond-Valence model is considered as an importal developmeat of recent solid state chemisty, which has three charederistics of simplicityt stability and practicality. It shows special advantage in the study of atomic valence distribution, site distortion and the deterxnination of bond length. So it is worth to be studied and improved. Its principle and applications are iatroduced in this Paper. A few comments about its prospects are also given here.
