摘要: An MHD model of a polar coronal hole based on white light coronagraph observations is used to make predictions plasma in the spacecraft frame along trajectory for Solar Probe Mission. This study will identify design requirements situ instrumentation with regard field-of-view issues, energy coverage, instrument geometric factors and mass separation requirements. The must consider need accurately observe wave motions electron heat flux both which are thought play an important role expansion. These emphasize 3-D measurements requirement nadir viewing.
