本文用直接数值积分的方法研究了合并致密双星系统的潮汐和潮汐共振效应。对于恒星，使用多方模型。潮汐效应被发现是占主导地位的（非共振）$f$-模式。得到了g模潮汐共振的影响。潮汐相互作用的兴趣，特别是低质量的双星。存在一个特征性的最终坍落轨道，超过该轨道，即使不考虑辐射反应，系统也不能保持稳定;这与Lai等人的结果一致。讨论了这些效应对地球引力波观测的重要性。
Tidal and tidal-resonant effects in coalescing compact binary systems are investigated by direct numerical integration of the equations of motion. For the stars polytropic models are used. The tidal effects are found to be dominated by the (non-resonant) $f$-modes. The effect of the $g$-mode-tidal resonances is obtained. The tidal interaction is shown to be of interest especially for low-mass binaries. There exists a characteristic final plunge orbit beyond which the system cannot remain stable even if radiation reaction is not taken into account; in agreement with results obtained by Lai et al. \shortcite{Lai93}. The importance of the investigated effects for the observation of gravitational waves on Earth is discussed.
