【摘要】：从历史文献中搜集了OQ 530最完备的射电波段(4.8,8,14.5,22和37 GHz)和光学B波段的光变数据,利用三种不同的周期分析方法(结构函数法、J-K方法和功率谱法)对6个波段光变曲线的周期性进行了分析.利用离散相关函数法对射电波段之间以及射电与光学波段之间的相关性进行了分析.周期性的分析结果显示4.8 GHz可能存在3.89 3.94 a的周期,8 GHz可能存在2.48 2.55 a的周期,14.5 GHz可能存在2.44 2.56 a的周期,22 GHz可能存在2.34 2.56 a,4.16 4.30 a的周期,37 GHz可能存在2.31 2.58a的周期,光学B波段可能存在的0.97 1.15 a的周期.相关性分析显示OQ 530在5个射电波段之间存在较强相关,延迟方面无明显变化规律.光学与射电波段之间的相关性显示光学波段要超前于射电波段,且随频率的逐渐变小延迟有逐渐增大的变化趋势.
[Abstract]:From the historical literature, we collected the most complete optical data of OQ530 in the radio wave band (4.8b) and the optical band B (14.5 GHz and 37 GHz).Three different periodic analysis methods (structural function method J-K method and power spectrum method) are used to analyze the periodicity of the six band phototropic curves.The correlation between radio bands and between radio and optical bands is analyzed by using discrete correlation function method.The results of periodic analysis show that there may be a period of 3. 89 ~ 3. 94 a period of 8 GHz for 4. 8 GHz, and a period of 2. 48 ~ 2. 55 a period of 14. 5 GHz may exist at 2. 44? 2. 56 a period of 2. 22 GHz. There may be a period of 2. 34 卤2. 56 a / 4. 16 / 4. 30 a period of 37 GHz and a period of 2. 31 / 2. 58 a.The optical B band may have a period of 0.97 ~ 1.15 a.Correlation analysis showed that OQ530 had strong correlation among five radio bands, but there was no obvious change in delay.The correlation between the optical and radio bands shows that the optical band is ahead of the radio band and the delay increases with the increasing frequency.
