| 摘 要： | 本文利用Ｔｕ和Ｍａｒｓｃｈ（１９９０）导出的串级函数和Ｈｅｌｉｏｓ飞船的观测数据计算了太阳风中磁流体湍流的串级率，计算表明当取ａ＝０．４１时，湍流能量串级率与质子加热率在０．３ＡＵ至１ＡＵ处有近似相同的径向变化。

| Abstract: | The energy-cascade function of the solar wind turbulence suggested by Tu andMarsch (1990) has been calculated and compared with the heating rate of the solar wind protons by using the Helios observational results. It is found that when the cascade constant a is taken to be 0.41, the radial evolution of the cascade function is appro-xiznately consistent with the radial evolution of the heating rate for both high speed and low speed Winds. The difficulty for an accurate comparison is briefly discussed. |
