摘　　要：本文首次报道了在1990年4—5月期间,2cm波段上叠加在微波爆发上的时间精细结构。The temporal fine structure (FS) superposed on the microwave solar burst was observed at 2 cm band during April-May, 1990. It has the charactristic of low intensity and short duration similar with millimeter wave FS. The intensity of the FS is 20-40 s.f.u., i.e. (5-9)σ (σ is the r.m.s. value of receiver noise) and its duration △t is 0.1-2.5s. The temporal profile of FS event on 23 May has been presented.
