计算了IRAS星系在四个场中的两点关联和关联分维。结果表明，这些场中的星系都是小尺度的星系团。在更大的尺度上，这种分布可以很好地用多层分形来近似描述。在更大的尺度上，可以通过非归一化对计数来检测分布中存在的典型尺度。如果我们将这四个场合并为一个样本，结果与其他观测数据得到的结果是一致的。
The two-points correlations,correlation fractal dimensions are calculated for IRAS galaxies in four fields.The results show that galaxies in all these fields are clustering in small scales.On larger scales the distribution can be approximately described by multilevel fractal very well.On even larger scales,the typical scales existed in the distribution can be detected by unnormalized pair counting.If we combine these four fields into one sample, the results are consistent with that obtained from other data given by surveys.
