| 英文摘要 | By performing one-dimensional (1-D) hybrid simulations, we analyze in detail the parametric instabilities of the Alfven waves with a spectrum in a low beta plasma. The parametric instabilities experience two stages. In the first stage, the density modes are excited and immediately couple with the pump Alfven waves. In the second stage, each pump Alfven wave decays into a density mode and a daughter Alfven mode similar to the monochromatic cases. Furthermore, the proton velocity beam will also be formed after the saturation of the parametric instabilities. When the plasma beta is high, the parametric decay in the second stage will be strongly suppressed. |
