本文介绍了一种新的红外JHKL测光方法，它是对141个IRAS天体的测光，这些天体是根据它们的IRAS颜色选择的，它们分布在银河系隆起的两条带中，|B| < 8°和345°<1 < 15°。确定了源的性质、变量的周期和辐射热量值。分析了样本中确定的113颗Mira星的性质。
New-infrared JHKL photometry is presented for a sample of 141 IRAS objects, selected on the basis of their IRAS colours and lying in two strips across the Galactic Bulge between 7°< |b| < 8° and 345°< l < 15°. Natures of the sources, and periods and bolometric magnitudes of the variables are determined. Properties of the 113 Mira stars identified in the sample are analysed.
