介绍了海森堡模型的不同位型[N,n](N为海森堡链总格点数,n为格点中自旋向下的电子数)中的体现本征值获取难易程度的本征值获取概率及其相应信息熵(香农所定义的)和体现模型体系关联程度的自旋向下电子发现概率、每一粒子的von Neumann及体系的平均von Neumann熵,可为量子计算与信息传递提供启示性信息.研究结果表明:1)事件发生概率大于(小于)50％时,信息熵随概率增加而减小(增加).2)不同位型[N,n],当n(N)同,N(n)增加时:本征值获取概率减小,其相应的信息熵正确反映本征值获取的难易程度；模型参数一定时,格点中自旋向下电子发现概率与每一粒子的von Neumann熵及体系的平均von Neumann熵都分别减小(增加).3)位型[N,n]相同时,每一粒子的von Neumann熵及体系的平均von Neumann熵随参数变化时出现拐点,显示体系发生量子相变的信息.4)同位型[N,n]且同参数时处于海森堡链对称位置粒子的von Neumann熵相同.
