我们考虑由任意数量的正负离子交替组成的一维离子晶体。我们精确地计算了每个离子的能量,并发现了一些有趣的模式。结果表明,如果体系的总电荷不为零,则每增加一个离子,每增加一个离子的能量就保持不变。另一方面,如果这种离子的加入导致电荷中性系统的总电荷为零,则每个离子的能量总是降低的。文中给出了显式的分析结果。
We consider a one-dimensional ionic crystal consisting of an arbitrary number of alternating positive and negative ions. We calculate exactly the energy per ion and uncover some interesting patterns. It is found that the energy per ion remains constant each time the size of the system increases by one ion if addition of such an ion leads to a system with a nonzero total charge. On the other hand, the energy per ion always decreases if addition of such an ion leads to a charge neutral system with a zero total charge. Explicit analytical results are provided.
