Abstract

Properties of plasma turbulence in the solar wind can be determined from radio frequency fluctuation measurements recorded during solar conjunctions. Noteworthy recent results were obtained from radio occultation experiments performed with the spacecraft Galileo in the interval 1994–2002 and Ulysses in 1991–1997. The power spectral index was calculated for the range of heliocentric distances 5 RS

来自无线电掩星数据的太阳风湍流
太阳风中等离子体湍流的特性可以通过在太阳结合期间记录的无线电频率波动测量来确定。最近值得注意的结果是伽利略号航天器在1994-2002年间和尤利西斯号航天器在1991-1997年间进行的无线电掩星实验。计算了日心距离5 RS
