英文摘要： In recent years，with the development of Chirped Pulse Amplification technique， laser pulses with focused intensities I=10^18-22 W/cm^2 and pulse width t<ps are available in many laboratories．The study of the interaction of ultrashort intense laser pulses with plasmas，which is motivated primarily by the fast ignition scheme of inertial confinement fusion，has received more and more attention. There are a lot of nonlinear phenomena in the interaction of ultra-intense ultra-short laser and underdense plasma. The investigation of the phenomena will be very useful for people to understand the mechanism of laser plasma interaction, At the same time, it has very important guidance meaning for the future experiment. The purpose of This thesis is: In order to understand the generation electromagnetic instability and electron thermal conduction characteristics in the process of the interaction between ultrashort intense laser pulses and plasma，the electron conduction and electromagnetic instability in anisotropic plasma under linear polarized high intense laser were estimated by means of electromagnetic relativistic particle-in cell program simulation
