一、引言金属键为三种主要化学键之一种,存在于金属单质及合金中。金属的若干物理性质如熔点、沸点,及机械强度等或多或少均与金属结构及键的强度有关,近年应用量子力学方法,对于一些硷金属的处理已获得相当成功,亦即从理论上可以相当准确地解释它们的升华热及晶格常数。不过对于一般的金属,就它们键的强度及影响键强的因素,作一经验的概括及探讨,亦颇有价值并饶兴趣。以前若干作者曾指出键能可能
I. INTRODUCTION Metal bond is one of the three main chemical bonds present in single metal and alloy. Some of the physical properties of metals such as melting point, boiling point, and mechanical strength are more or less related to the strength of the metal structure and the bond. In recent years, quantum mechanics has been applied to the treatment of some alkali metals. In other words, theoretically Their sublimation heat and lattice constants can be fairly accurately explained. However, for general metals, it is also valuable and interesting to make an empirical summary and discussion of the strength of their bonds and the factors that influence them. Several authors have pointed out that the key can be
