In this paper we separate the Hamiltonian into three parts: a spherical symmetry Hamiltonian; a z-component of the angular momentum operator, and a non-spherical symmetric potential as the perturbation operator, and provide a propose method by separating the potential containing squared magnetic field B^2 into two parts spherical symmetric and non-spherical symmetric ones so that the first-order energy correction due to the non-spherical symmetric potential is zero, and the second-order correction due to B^2 can be obtained by a simple variational method.

"Such findings suggest that the relationship between disturbed sleep and pain is bidimensionsal not only does pain disrupt sleep, but disrupted sleep may enhance pain," Timothy A Roehrs, PhD, lead investigator, told Medscape."We were interested in determining whether loss of REM sleep itself is hyperalgesic."

Timothy A Roehrs博士向Medscape表示，这项试验结果显示，被干扰的睡眠与疼痛之间的关系是双向性的；亦即，疼痛不仅会阻扰睡眠，睡眠受到阻扰也会加强疼痛的感觉；我们想要探究的是，短少的REM睡眠，本身是否就是痛觉过敏。
