| 8. | The last chapter presents the result of our studies of how to use the peak frequency of synchrotron emission to classify the bl lac objects and the action of the peak frequency in bl lac objects . we sustain that the peak frequency can become a well classificatory criteria of bl lac objects and conceive that there are some systemic difference between xbls and rbls , and the difference is not only the result of choice
本文最后一章重点介绍了同步峰频在bllac天体分类中的作用，同时介绍了作者在相关领域作的一些研究工作，我们的工作进一步支持了峰频作为bllac天体的一个有效的分类标准的观点，进一步猜想bllac天体的两个子类xbl和rbl的物理性质可能存在本质差异，而不仅是选择效应的结果。 |
| 9. | On the basis of the former research works , we present the detecting method as follows : for the narrow band characteristic of the track signal we use under - sampling instead of nyquist sampling to reduce the sampling rate . as to the carrier frequency , the spectrum of the 18 - information frequency - shift track signal has two peaks , then the carrier frequency is the average of the two peak frequency , to um - 71 jointless track signal , it has only one peak , then the carrier frequency is the peak frequency
针对移频轨道信号的窄带特性提出了使用欠采样技术代替奈奎斯特采样的方法,以降低信号的采样频率;国产18信息移频轨道信号频谱具有双峰,双峰频率平均值就是信号的载频频率,而um - 71无绝缘轨道信号频谱单峰,峰值频率即为信号的载频频率。 |
| 10. | The method has been used to separate the frequent spectra of incident waves and reflected waves of the composed wave that are simulated by a numerical method . the results shown that the frequent spectra of incident waves and reflected waves being computed are consistent with the target spectrum and the bulk reflection coefficient is too . the frequent spectrum of reflection coefficient is same as the input round the peak frequency
将此方法用模拟合成波波列的分离计算，结果表明，分离的入、反射波频谱与输入的靶谱符合良好，且计算的总体反射系数与输入的总体反射系数一致，计算得到的反射系数频率谱在峰频附近与输入值符合良好，说明该分析方法是可靠的。 |
