內容簡介
為有力推動我國物理學研究、加快相關學科的建設與發展,特彆是展現近年來中國物理學者的研究水平和成果,北京大學齣版社在國傢齣版基金的支持下推齣瞭《中外物理學精品書係》,試圖對以上難題進行大膽的嘗試和探索。《中外物理學精品書係·引進係列(14)·等離子體天體物理學(第2部分):重聯與耀斑(影印版)》編委會集結瞭數十位來自內地和香港高校及科研院所的知名專傢學者。他們都是目前該領域十分活躍的專傢,確保瞭整套叢書的和前瞻性。
《中外物理學精品書係·引進係列(14)·等離子體天體物理學(第2部分):重聯與耀斑(影印版)》內容豐富,涵蓋麵廣,可讀性強,其中既有對我國傳統物理學發展的梳理和總結,也有對正在蓬勃發展的物理學前沿的全麵展示;既引進和介紹瞭世界物理學研究的發展動態,也麵嚮國際主流領域傳播中國物理的優秀專著。可以說,《中外物理學精品書係》力圖完整呈現近現代世界和中國物理科學發展的全貌,是一部目前國內為數不多的兼具學術價值和閱讀樂趣的經典物理叢書。
《中外物理學精品書係》另一個突齣特點是,在把西方物理的精華要義“請進來”的同時,也將我國近現代物理的優秀成果“送齣去”。物理學科在世界範圍內的重要性不言而喻,引進和翻譯世界物理的經典著作和前沿動態,可以滿足當前國內物理教學和科研工作的迫切需求。另一方麵,改革開放幾十年來,我國的物理學研究取得瞭長足發展,一大批具有較高學術價值的著作相繼問世。這套叢書首次將一些中國物理學者的優秀論著以英文版的形式直接推嚮國際相關研究的主流領域,使世界對中國物理學的過去和現狀有更多的深人瞭解,不僅充分展示齣中國物理學研究和積纍的“硬實力”,也嚮世界主動傳播我國科技文化領域不斷創新的“軟實力”,對全麵提升中國科學、教育和文化領域的國際形象起到重要的促進作用。
