摘要
本文对小质量X射线双星的准周期振荡的差频模型做了修正和补充。修正的要点是:要考虑柱吸积过程中的粘滞阻尼。由此即可成功地解释QPO天体GX5-1的双分支谱特性。
Some corrections and improvements to the beat frequency model for the quasi-periodic oscillation phenomenon in X-rays binaries have been made in this paper. The main point is that the viscous damping in the column accretion process has been taken into consideration, which successfully accounts for the two-branch spectrum behaviour unexplained by the previous beat frequency model.
