Theoretical researches on solar activity , solar flare and cme were involved in many fields of foundational physics such as plasma astrophysics , magnetohydrodynamics ( mhd ) and so on . the forecast of solar activity , a main branch of space weather , was becoming more and more significant for preventing space disaster and for many aspects of space science 探索太陽(yáng)活動(dòng)的規(guī)律、太陽(yáng)耀斑及其伴隨cme的先兆、觸發(fā)過程及能量傳播機(jī)制等等,從理論上推動(dòng)了等離子體天體物理、磁流體力學(xué)等諸多基礎(chǔ)理論的發(fā)展,有著重要的理論意義;而對(duì)太陽(yáng)活動(dòng)的預(yù)報(bào),是國(guó)際前沿科學(xué)?空間天氣學(xué)的重要組成部分,對(duì)避免空間災(zāi)害、為航空航天科學(xué)提供服務(wù)等方面,具有重大的實(shí)際應(yīng)用價(jià)值。
