朱邦芬只保留电子-声子互作用算符 对角项，把非对角项作为微扰处理； 原则上，不同的电子态对应于不同的晶格平衡位置；通常计算固体的振动性质时，假定电子处于基态。 (Zhu bonfim retain only electronic- phonon interaction diagonal operator, the diagonal of the non-perturbative as processing in principle, different electronic states corresponding to different lattice equilibrium position usually calculate the vibration of the solid nature, it is assumed that e in the ground state.)

正方形ABCD的4个顶点各有1人.在某一时刻,4人同时出发以匀速v=10m/s按顺时针方向追逐下一人,如果他们始终保持对准目标,则最终按螺旋状曲线于中心点O.试求出这种情况下每个人的行进轨迹(Four vertices of square ABCD each one. At a time, 4 people starting at a uniform v = 10m/s in a clockwise direction chasing the next person, if they remain at the target, then press the spiral curve in the final Find the center point O. This road track of each person)
