论文摘要
在手稿中，我们讨论了SDSS J1042-0018的属性，该属性是宽线AGN，但在BPT图中被错误地分类为HII星系（SDSS J1042-0018称为错误分类的宽线AGN）。考虑到高斯或洛伦兹函数要描述的宽Balmer线，不同模型函数周围和H $β$周围的发射线被不同的模型函数很好地描述。不同的模型功能导致不同确定的窄发射线通量，但是不同的窄发射线通量比将SDSS J1042-0018导致BPT图中的HII星系。为了解释错误分类的宽线AGN SDSS J1042-0018的独特特性，提出了两种方法，具有高度电子密度的恒星贡献和压缩的NLR，接近禁止发射线的临界密度。幸运的是，在SDSS J1042-0018中，强大的星形贡献可以优选。通过星形贡献很好地解释了错误分类的宽线AGN SDSS J1042-0018，可以提供有关BPT图在正常宽线AGN应用的进一步线索。
In the manuscript, we discuss properties of the SDSS J1042-0018 which is a broad line AGN but mis-classified as a HII galaxy in the BPT diagram (SDSS J1042-0018 called as a mis-classified broad line AGN). The emission lines around H$α$ and around H$β$ are well described by different model functions, considering broad Balmer lines to be described by Gaussian or Lorentz functions. Different model functions lead to different determined narrow emission line fluxes, but the different narrow emission line flux ratios lead the SDSS J1042-0018 as a HII galaxy in the BPT diagram. In order to explain the unique properties of the mis-classified broad line AGN SDSS J1042-0018, two methods are proposed, the starforming contributions and the compressed NLRs with high electron densities near to critical densities of forbidden emission lines. Fortunately, the strong starforming contributions can be preferred in the SDSS J1042-0018. The mis-classified broad line AGN SDSS J1042-0018, well explained by starforming contributions, could provide further clues on the applications of BPT diagrams to the normal broad line AGN.
