科研成果

主要在地球輻射帶高能粒子環境擾動過程和機制方面取得了一些重要的研究成果。1）首次提出磁層哨聲模合聲波和壓縮ULF波對輻射帶高能電子的複合加速機制，並發現由於壓縮ULF波可以加速能量較低的“種子電子”達到和哨聲模波共振的能量範圍，從而提高了電子的整體加速效率[Li et al., 2005]。該論文的單篇引用率超過66次。2）統計獲得了輻射帶高能電子突增和磁暴/亞暴活動強度的關係，發現亞暴活動越強，輻射帶高能電子的含量越高[Li et al., 2009]。該結果被美國輻射帶暴探測項目列為一個重要的科學目標之一。3）獲得了輻射帶高能粒子對太陽風動壓增加和行星際磁場南向偏轉的回響規律[Li etal., 2013, 2016; Yu et al., 2016].等等。
