摘　　要：应用Du和Delos等人的半经典闭合轨道理论,将研究范围由二维空间推广到了三维。通过这一理论推导出了当电场和磁场成任意夹角时H^-的光剥离截面的计算公式,并且计算了几种不同夹角的光剥离截面,结果表现出很大的振荡特性。By the semiclassical closed-orbit theory of Du and Delos et al., the research space is extended from two-dimensions to three-dimensions. Through this theory, the formulation of the H' photodetachment cross section is deduced under strong electric and magnetic fields with arbitrary orientation, and the photodetachment cross sections of H' with different degrees are calculated. The results show promi-nent modulation.
