摘要：

Typical in situ spacecraft measurements made in the solar wind show that charged particle velocity distribution function (VDF) contains energetic component with quasi scale-free power-law velocity dependence, f similar to nu(-alpha). This paper proposes a theory for quiet-time solar-wind electrons that are in dynamical equilibrium with plasma turbulence. The theory predicts f similar to nu(-6.5) for high electron velocities, while observations by WIND and STEREO spacecraft reveal nu(-5.0) to nu(-8.0) dependence. This shows that theory falls within the observed range.
