摘要：

In a VLBI experiment, using the Westerbork synthesis radio telescope as a total power array and the Effelsberg 100-m dish,'hot spots' with sizes ≲0.15 have been detected in the lobes of several 3CR radio sources of high redshift. The individual lobes of double sources and the hot spots within them may have been smaller at earlier epochs. © 1979 Nature Publishing Group."
