Finally, we phenomenologically separate phase according to magnetic fields, the results is consistent with our new idea where we use the Hamiltonian with curved surface to analyze XY model. In chapter Ⅳ, we make two hypotheses: the system has one-step time correlation and two-step time correlation. We find the effect of Ratchet potential is similar to OSTC which changes the system's relaxation. TSTC may facilitate the system to move forward or backward along the nonlinear wave of the thermal fluctuation.

第四章，我们进一步作了两个唯象的假设：体系有一步和两步时间关联；发现Ratchet势与一步时间关联有相似效果——改变了体系对热噪声的驰豫；而两步时间关联项则能够促使体系在热噪声的非线性波形上定向&冲浪&，或者促使体系躲避热噪声的扰动保持在势阱底部。
