After a long time evolution, the system finally reaches a stable state at which the magnetization and the equal time spin - pair correlation are periodic oscillating functions with the equal period as the external field. numerical simulation shows : when the amplitude of external filed is large, there exits a particular temperature at which the average magnetization and the average spin - pair correlation are almost unaltered with various field amplitude ( i. e. magnetic susceptibility is zero ), and the particular temperature depends on the number of the spin states, cutting down with q increasing
由數值模擬得到：當外場幅度較大時，存在一個特殊的溫度點（我們稱之t ） ，在這個溫度點，系統的平均磁化強度和平均等時自旋對關聯隨外場幅度的變化幾乎保持不變（即磁化率為零） ，並且這個溫度的大小依賴于自旋態數目q的變化， q越大，這個溫度就越小；而當外場較小時，確信系統存在有限大小的臨界溫度 -
Based on the weighted average method adopted in the first part, and by using numerical simulation and monte carlo simulation, we further present a study of the dynamics of id and q states potts model under an oscillating external field
