摘　　要：本文提出了一个计算氢化物分子键长γ_AB的新公式γ_AB=1.40F_y+0.32n_A^*+0.13（3n_B-N_B）并对34个氢化物的分子键长进行了计算,其结果与实验值相一致,说明新公式是正确的。On the basis of disecussion the relation between of the chemical bonds and ionic of bonds,Sister rule,this paper puts formula of Hy- dride molecule bonds length γ_(AB) as follows: ■ Where Fy is the ionic percentage of bonds,n~*_A is the effective primary quantum numbers of A atom,~nB and N_B are the peridic and group numbers of B atom.The bonds lengths of 34 Hydride molecules above are calculated by the equation.The extent of the calculating values coinciedes with the experiment and proved to be a correct me- thod.
