| 摘 要： | 在高速太阳风中，Ａｌｆｖｅｎ波在传播过程中其能量可能转移给快磁声波，当磁场强度和Ａｌｆｖｅｎ波速度趋于零时，快磁声波将转变为离子声波。通过对质子的随机湍动加热，而导致高速太阳风中质子平均温度高于电子的平均温度。

| Abstract: | During a propagating process of Alfven waves in high-speed solar wind,Alfvenwave energy can be transferred into fast magnetosonic waves.When both magnetic field andalfven wave velocity approach zero,fast magnetosonic waves will be transferred into ion-acoustic waves.As the phase velocity of ion-- acoustic waves is slightly greater than the thermalvelocity of protons,the turbulence energy of ion- acoustic waves can largely be absorbed byprotons. Thus the mean temperature of protons ingeater than one of electrons by stochastieturbulence heating of ion-acoustic waves for protons. |
