摘要
本文比较了两类射电源ＦＲ－Ⅰ和ＦＲ－Ⅱ型的射电－光学—Ｘ－ｒａｙ的谱特征。ＦＲ－Ⅰ射电源的射电－光学谱比ＦＲ－Ⅱ射电源平得多（△αｒｏ≈０．１９）；但对于光学－Ｘ－ｒａｙ和射电－Ｘ－ｒａｙ谱，ＦＲ－Ⅰ却比ＦＲ－Ⅱ陡得多（△αｏｘ≈０．４０；△αｒｘ≈０．１０）。初步结果表明，ＦＲ－Ⅱ（Ｇ）可能是ＦＲ－Ⅱ（Ｑ）向ＦＲ－Ⅰ过渡的中间状态。
The radio-optical-X-ray spectral properties of the FR- Ⅰ and the FR- Ⅱ type radio sources are compared in this paper. The FR- Ⅰ radio sources have much flatter radio-optical spectra (△αro≈0. 19), but much steeper optical-X-ray and radio-X-ray spectra (△αox≈0.40; △αrx≈0. 10). There is a marginal evidence that FR-Ⅱ (G) might be the intermediate state from FR-Ⅱ (Q) to FR- Ⅰ radio sources.
