摘要
本文提出了用键长估算键能的关系式：E=式中dAB为键长，E为键能，XA和XB是成键元素A和B的pauling电负性值．a0为与电子结构有关的参数，K=15.65为验常数，该公式是用dAB估算不同非金属原子之间的键能（E）值．键能（E）的估算值与实验值的平均误差为3．426kJ·mol-1．本文的研究找到了用共价键长直接估算键能的关系式．
In this paper,the evaluation of bond length and bond energy is suggested as follows: where dAB is bond length, E is bond evergy, XA and XB represent pauling electronegativity of elements A and B, a0 is periodic factor, K is an empirical constant of 15. 56. Thebond energy of the between non-metal atoms are calculated with this equation, and the average difference between calculated and experimental bond energy is 3. 426kJ. mol-1
