讨论了平均汉密尔顿理论的有效性问题。这是来自考虑的Floquet定理周期系统。一个微扰计划的开发和示出给平均哈密顿量相当于从马格努斯展开。收敛条件取决于共振的存在。这些结果被应用于脉冲自旋锁定实验的讨论。
The question of the validity of the average Hamiltonian theory is discussed. This is derived from consideration of the Floquet theorem for periodic systems. A perturbation scheme is developed and shown to give an average Hamiltonian equivalent to that obtained from the Magnus expansion. The convergence condition is shown to depend on the existence of resonances. These results are applied to a discussion of pulse spin-locking experiments.
