本文研究了椭圆三体问题（一个密近双星和一个近邻伴星，三维情况），以阐明某些密近双星系统拱点运动异常的性质。一次和两次平均的问题的数值结果。结果表明，DI Her近点运动的观测值与理论值之间的显著差异（相对论效应和经典效应）可能是由第三体对密近双星的扰动引起的
The elliptical three-body problem (a close binary and a nearby companion, three-dimensional case) in examined to elucidate the nature of anomalies in apsidal motion of some close binary systems. The numerical results are presented for once- and twice-averaged problems. It is shown that the significant discrepancy between the observed and the theoretical apsidal motion of DI Her (relativistic and classical effects) possibly results from the close binary perturbations due to a third body
