| 摘 要： | The temporal cvolution of relalivistic electrons in radio jets is obtained by numerically solving the kinetic equation of the interaction between charged particles and Alfven turbulence, including synchrotron radiation loss. The energy of relativistic eieclrons can be accelerated to as high as Lorentz factor r-106. The energy spectrum of energetic eietrons is a power law, and the acceleration time is about 1012-1014 seconds. The energy spectum index of electrons is almost indcpcnded on the Alfven wave spectrum index and synchrotron loss, The latter affects the energy up-limit of acceleration.
