目的：在我们以前的论文中已经介绍的研究的基础上，北欧光学望远镜（NOT）的样本，其中包括五个星系团的红移范围为0.18 $\leq$ z $\leq$ 0.25，在非常好的视宁度条件下，在中央0.5-2 Mpc成像，我们研究了它们的明亮星系人口的定量形态学方法：我们分析了这些星系团中星系群的表面亮度分布。在此之前，我们已经进行了模拟，以检查拟合的可靠性。我们还导出了一个数量形态分类。结果：对由这些分析得出的结构参数进行了分析。结果表明，E/S_0星系的结构参数与低红移星系团中星系的结构参数相似。然而，光盘的规模是不同的。特别是，在中等红移星系团的星系盘的规模是统计上不同于那些位于后发座星系团类似的星系。但是，中红移星系团中星系盘的尺度与近场星系相似。结论：结果表明，星系团中星系盘成分的演化速度比场星系快。像星系骚扰这样的机制显示了$\sim 1$ Gyr的时间尺度，可能是这种盘尺度演化的原因。这表明星系团中的螺旋星系在过去的2.5 Gyr中经历了强烈的演化，或者Coma在某种程度上是异常的。
英文摘要：
Aims: Following the study already presented in our previous paper, based on the Nordic Optical Telescope (NOT) sample, which consists of five clusters of galaxies within the redshift range 0.18 $\leq$ z $\leq$ 0.25, imaged in the central 0.5-2 Mpc in very good seeing conditions, we have studied the quantitative morphology of their bright galaxy population
Methods: We have analyzed the surface brightness profiles of the galaxy population in those clusters. Previously, we have performed simulations in order to check the reliability of the fits. We have also derived a quantitative morphological classification.
Results: The structural parameters derived from these analysis have been analyzed. We have obtained that the structural parameters of E/S0 galaxies are similar to those showed by galaxies in low redshift clusters. However, the disc scales are different. In particular, the scales of the discs of galaxies at medium redshift clusters are statistically different than those located in similar galaxies in the Coma cluster. But, the scales of the discs of galaxies in medium redshift clusters are similar to nearby field galaxies.
Conclusions: The results suggest that the evolution of the disc component of galaxies in clusters is faster than in field ones. Mechanisms like galaxy harassment showing timescales of $\sim 1$Gyr could be the responsible of this disc scale evolution. This indicates that spiral galaxies in clusters have suffered a strong evolution in the last 2.5 Gyr or that Coma is in some way anomalous.
