Because, statistically, heat capacity, energy, and entropy of the solid are equally distributed among its atoms (SHOs), we can work with this partition function to obtain those quantities and then simply multiply them by N ′ {\displaystyle N^{\prime }} to get the total.
因为，统计上来说，固体的热容、能量，以及熵，都是在它的原子（SHO）中均匀分布的，因此我们可以利用这个配分函数来获得这些物理量，然后直接把它们乘以 N ′ {\displaystyle N^{\prime }} 以得出总量。
