| 摘 要： | 依据类氢化近似理论和轨道最大重叠原理对原子共价成键提出一个直观的近似物理模型。模型确定:σ键重叠位置是两成键原子p价电子云的最大几率平面相重合的位置,π键重叠位置是两成键原子p价电子云最外极大几率环相接触的位置,构成重键时价电子云重叠取σ键和π键的平均重叠位置。由此计算出来的共价单键、双键和叁键之间的键长关系基本符合共键长间的经验关系。本文模型较之Pauling的弯键模型有较厚实的理论基础。

| Abstract: | According to the quasi-hydrogen approximate theory and the greatest obital overlap principle, acovalent bonding approximate model is proposed. The model shows us clearly the locations of bondingobital overlap. The relations of the covalent bond lengths calculated by the model agree with the empir-ical ones. This model is better than Pauling's theory. |
