英文摘要	The lower mantle discontinuities are an important part of the structure of earth's interior and very important for understanding the dynamic process of the deep part of the earth. the waveform data of the deep events of south america recorded by the dense stations at western part of usa are suitable for studying lower mantle discontinuities beneath the events. in the paper, 19 sets waveform data of vertical short period component from 15 events beneath south america recorded by the pnsn and uuss of usa were retrieved and processed with 4-th root slant stack method for picking the sdp phases from the lower mantle interfaces. with the sdps, the conversion points related to sdps are found to be concentrated between 800 and 1200 km and mainly distribute at the depths of 900, 1000 and 1100 km. in addition, the topography of the three layers is different. the interfaces may relate to the mid-boundary of the two-layer mantle convection.
