摘要
用逐步回归分析法，发现电负性与键长的相关性较好，并提出了计算共价键键长的经验公式．
With the method of stepwise regression analysis,it has been discovered that electronegativity compared atomic other properties with possesses better relativity in bond length. Empirical formulas for calculating covalent bond length has been also recommended.
