The theory of Quasi-periodic Oscillation (QPO) in Low-mass X-ray Binaries (LMXB) is discussed in this paper. Beat-Frequency Models (BFM), including development, are presented in detail.
本文簡略地敘述了低質量X射線雙星中準周期振蕩（QPO）現象的理論解釋，對其中的差頻模型（BFM）和它的一些發展作了較爲詳細的介紹。
By means of the relations between frequency variances of oscillators and their beat-frequency variances, we can determine the frequency variances of oscillators without frequency standard.
利用振蕩器頻率的方差和它們的拍頻的方差之間的關系，可以決定某一振蕩器頻率的方差。
