摘要：
The nonlinear interaction between the high frequency Langmuir wave and the low frequency density fluctuation in ultrarelativistic isothermal electron positron plasmas is investigated from kinetic Vlasov equation. One dimensional Langmuir solitons are obtained, the width of which is so large that it is not relevant to the coherent pulsar radio emission.
