| 摘 要： | 由于非点源效应，行星际闪烁很强时，也会出现ｍ２１的情况，因此仅用ｍ２１作为弱散射的判据有时并不是很准确的．本文考查了行星际闪烁中闪烁指数随观测频率变化的规律，频率指数在弱散射时为１，而在很强散射时则为负值．利用这种性质可以判断散射的性质．

| Abstract: | Because radio source is not a point source,m2 is probable as IPS disturbance is strong.So to decide weak scattering by means of is not accurate.The frequency index is equal to 1 for weak scattering,but it will be negative as scattering is Strong.Thus,it is necessary to distinguish between weak scattering and very strong scattering by means of investigating the frequency index. |
