The internal partition function is frequently simply called the partition function or also the state sum. 内配分函数往往简称配分函数,也可称为态和。
In consideration of the strong intermolecular interactions in liquids, a hindering factor is introduced to modify the contribution of their rotation and vibration to the internal partition function. 考虑到液体分子间的强相互作用,引入了一个阻障因子,以修正其转动和振动对内配分函数的贡献。
