我们在宽视场红外巡天探测器（WISE）初步释放源目录（PRSC）中搜索斯隆数字巡天（SDSS）发射线星系的结果，这些星系具有非常红色的3.4µm - 4.6µm（W1 W2）颜色，旨在寻找具有热尘埃发射的物体。为此，我们考虑了从总共900000个SDSS光谱中选出的16000个具有强发射线的星系样本，并使用PRSC源对它们进行识别。我们发现，16000个SDSS星系中有5000个来源存在于PRSC中，其中包括1000个星系，它们具有足够强的[O III] 4363发射线，可以可靠地确定氧丰度。未发现W_1、W_2与金属丰度的相关性，但有明显的
We present the results of a search for Sloan Digital Sky Survey (SDSS) emission-line galaxies with very red 3.4µm - 4.6µm (W1 W2) colours in the Wide-field Infrared Survey Explorer (WISE) Preliminary Release Source Catalogue (PRSC) aiming to find objects with hot dust emission. For this purpose we considered a sample of � 16000 galaxies with strong emission lines selected out of a total of � 900000 SDSS spectra and identified them with the PRSC sources . We find that � 5000 sources out of the � 16000 SDSS galaxies are present in the PRSC, including � 1000 galaxies with sufficiently strong [O III] �4363 emission lines to permit reliable determinations of the oxygen abundance. No correlation of W1 W2 with metallicity is found. On the other hand, there is clear
