基本解釋

Explained the modulated phenomena in output pulse by use of horizontal mode beat-frequency.
實驗上證明利用單模雙包層光纖，在特定泵浦條件下獲得較穩(wěn)定的自脈沖輸出。
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(zhì)量X射線雙星中準周期振蕩（QPO）現(xiàn)象的理論解釋，對其中的差頻模型（BFM）和它的一些發(fā)展作了較為詳細的介紹。
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。
