摘　　要：自由Dirac方程正、负宇称电子解的简并性可造成计算一级微拢能量的不确定性。以纯宇称解作为微扰场论的零级波函数虽然直接,但缺乏有力的理论根据。选择零级电子波函数的任意性是推导泡利方程和做Foldy-Wouthuysen变换不确定性的根源。Degeneracy of parity even and odd electron solutions of the free Dirac equation may cau- se uncertainties in first order calculation of the perturbative energy. Choosing the even parity solution to start perturbation is though direct, not theoretically well supported. The arbitra- riness in choosing lowest order electron wave functions causes uncertainties in the Foldy--Wou- thuysen transformations and the reduction of the Pauli equation from the Dirac equation.
