morse势 meaning in English

morse potential

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
通过把获得的ecm势与morse势、 hms ( huxley - murrell - sorbie )势、 rkr ( rydberg - klein - rees )值或ipa ( inverted - perturbation - approach )值比较表明： morse势和hms势等一些常用的解析势能函数往往在长程区和渐近区出现较大、甚至很大的偏差， hms势还可能出现物理上错误的结构；而ecm势能函数不仅能满足正确的物理性质，并且在核间距变化的全程区域都能得到比较准确的势能。
