It is shown that the ecm potentials have better or much better agreement with rkr and ipa data than the widely used morse and hms potentials especially in the molecular asympototic and dissociation region , and that the ecm potentials can be not only well applied to homonuclear diatomic molecules , but also to heteronuclear diatomic molecules . the ecm potentials are particularly usefull to generate correct potential data in molecular asymptotic and dissociation region for some diatomic molecular states which may be difficult to obtain experimrntly or theoretically 通過把獲得的ecm勢與morse勢、 hms ( huxley - murrell - sorbie )勢、 rkr ( rydberg - klein - rees )值或ipa ( inverted - perturbation - approach )值比較表明: morse勢和hms勢等一些常用的解析勢能函數往往在長程區和漸近區出現較大、甚至很大的偏差, hms勢還可能出現物理上錯誤的結構;而ecm勢能函數不僅能滿足正確的物理性質,并且在核間距變化的全程區域都能得到比較準確的勢能。
