摘　　要：对分子之间的结合力进行了全面综合的解释:极性分子之间是通过其固有偶极矩而产生相互作用;极性分子与非极性分子是通过极性分子固有偶极矩与非极性分子的瞬时诱导偶极矩而产生相互作用;非极性分子之间是通过它们各自瞬时偶极矩的相互作用来相互作用的.这3种力分别称为葛生力、德拜力和伦敦力,本文给出了这3种力的相对大小,这对理解分子晶体的结合具有重要意义.In this paper,the combination forces between molecules were comprehensively explained as follows： polar molecules interact on each other through their natural electric dipole moments;a polar molecule interacts on a non-polar molecule through their natural electic dipole moment and instantaneous electric dipole moments;non-polar molecules interact on each other through their individual instantaneous electric dipole moments.The three forces are called Keesom,Debye and London forces.The relative strength of the three forces are provided at the same time,which is very important for understanding the combination of molecules.
