摘要：

A total of 22 optically selected high-redshift (z > 3. 1 ) quasars have been observed at 5 GHz (6 cm) with the VLA. The measured radio properties of low-redshift optically selected quasars indicate that we should have detected radio emission from almost-equal-to 5-10 objects in our sample, but only one quasar (z = 4.093) has a radio flux above our 5-sigma-limit of almost-equal-to 0.2 mJy.
