Abstract:Six complete samples of radio sources have been analysed by the Spearman rank and the Spearman partial-rank correlation coefficients. The relations between the radio luminosities and linear sizes as well as between linear sizes and redshift indicate that the observed angular diameter-redshift diagram may be explained by the changes of linear sizes with radio luminosity of radio sources.
