Abstract: Electron initial velocity distribution of two kinds of parctical thermionic cathodes are studied with pre-acclerating-post-deaccelerating type retarding field method. Based on the theory of dynamical surface emission centers, the phenomenon, i.e. the electron initial velocity distribution of the oxide-coated cathode splits into spectrums under strong pulse ele-ctric field, is explained. -
