摘　　要：ASTEROSEISMOLOGY of pulsating white dwarfs is an effective tool for us to infer their internal structures and the activities of stars on the final stages of stellar evolution. DA-type pulsating white dwarfs, with hydrogen-rich shells and low temperatures, constitute an instability strip in the H-R diagram, which have only 24 members. In order to push forward the research work in this field, many astronomers have devoted themselves to the search of new possible members for a long time. During two nights on February of 1996, the authors observed five candidates selected from the Kiso survey (Noguchi et al., 1980; Kondo et al., 1984), with the 1.93-m telescope at Observatoire de Haute-Provence, France. In the present note, we report the discovery of two new variables from this observation run: KUV 08368+4026 and KUV 11370+4222.
