In this paper, we consider the symmetric loss function.

为此，传统的解决方法是在平方损失的条件下，将风险保费的估计量限定在样本的线性非齐次估计量中，并利用最小二乘法求得其最优线性非齐次可信性估计。

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.
