中文摘要：

共有原子价电子实质地决定无机的晶体的内在的坚硬。一个坚硬模型根据从 Paulings 共有原子价契约长度方程和契约长度差别方法产生的实验电子理论被介绍。无机的晶体的计算坚硬价值在对的好同意试验性并且另外的理论价值。有极性修正的共有原子价契约精力能被用作连接显微镜的电子结构到宏观的坚硬的内在的指示物。一契约精力的简单数学处理被执行扩大模型到多结合或多部件系统。共有原子价契约的空间分发在无机的晶体的坚硬上有大影响，这也被发现。

英文摘要：

Covalent electrons substantially determine the intrinsic hardness of inorganic crystals. A hardness model is presented on the basis of the Empirical Electron Theory generated from Pauling＇s covalent bond length equation and the bond length difference method. The calculated hardness values of inorganic crystals are in good agreement with experimental and other theoretical values. Covalent bond energy with polarity correction can be used as an intrinsic indicator linking microscopic electronic structure to macroscopic hardness. A simple mathematical processing of bond energy is performed to extend the model to multi-bonding or multi-component systems. It is also found that spatial distribution of covalent bonds has a great influence on the hardness of inor- ganic crystals.
