摘　　要：根据动力论Alfven波耗散机制，详细计算了动力论Alfven波衰减的能量分配给质子和电子的比率．初步解释了高速太阳风中质子温度比电子温度高的事实，定性说明了r＜10Rs时电子快速冷却的原因．The dissipation energy ratio of kinetic Alfven waves between proton and electrons is calculated in details based on the dissipation principle of kinetic Alfven waves. It provides a simple explanation of the fact of the higher proton temperature compared with electrons in high speed stream of the solar wind. The rapid cooling of electrons at r<10Rs is explained qualitatively.
