论文摘要
在这项工作中，采用支持向量机（SVM）方法在光子光谱索引中针对光子通量的图中分离bl lacertae对象（Bl lacs）和扁平光谱无线电数量（FSRQ），$α_ {\ rm ph} \ sim {\ rm sim {\ rm sim {\ rm log} $α_ {\ rm pH} \ sim {\ rm log} \，\ textit {v \！i} $，以及针对光子通量的可变性索引，$ {\ rm log} \，{v \！i}然后，我们使用划分线来告诉BL lac，从\ textit {fermi}/lat目录中的不确定类型的Blazars候选中的FSRQ告诉BL LAC。我们的主要结论是：1。我们将bl lac和fSRQ分为$α_ {\ rm ph} = -0.123 \，{\ rm log} \，f + 1.170 $ in $ a {\ rm ph} -0.161 \，{\ rm log} \，{v \！i} + 2.594 $中的$α_ {\ rm ph} \ sim {\ rm log} \，{v \！i} log} \，f + 9.203 $中的$ {\ rm log} \，{v \！i} \ sim {\ rm log} \，f $ plot。 2。我们获得了932个BL LAC候选者和可能的BL LAC候选物，以及585名FSRQ候选者和可能的FSRQ候选者。 3。与文献中的比较进行了一些讨论。
In this work, the support vector machine (SVM) method is adopted to separate BL Lacertae objects (BL Lacs) and flat spectrum radio quasars (FSRQs) in the plots of photon spectrum index against the photon flux, $α_{\rm ph} \sim {\rm log}\,F$, that of photon spectrum index against the variability index, $α_{\rm ph} \sim {\rm log}\, \textit{V\!I}$, and that of variability index against the photon flux, ${\rm log}\,{V\!I} \sim {\rm log}\,F$. Then we used the dividing lines to tell BL Lacs from FSRQs in the blazars candidates of uncertain types from \textit{Fermi}/LAT catalogue. Our main conclusions are: 1. We separate BL Lacs and FSRQs by $α_{\rm ph} = -0.123\,{\rm log}\,F + 1.170$ in the $α_{\rm ph} \sim {\rm log}\,F$ plot, $α_{\rm ph} = -0.161\,{\rm log}\,{V\!I} + 2.594$ in the $α_{\rm ph} \sim {\rm log}\,{V\!I}$ plot, and ${\rm log}\,{V\!I} = 0.792\,{\rm log}\,F + 9.203$ in the ${\rm log}\,{V\!I} \sim {\rm log}\,F$ plot. 2. We obtained 932 BL Lac candidates and possible BL Lac candidates, and 585 FSRQ candidates and possible FSRQ candidates. 3. Some discussions are given for comparisons with those in literature.
