前言

大學最重要的功能是向社會輸送人才。大學對于一個國家、民族乃至世界的重要性和貢獻度,很大程度上是通過畢業(yè)生在社會各領域所取得的成就來體現(xiàn)的。中國科學技術大學建校只有短短的五十年,之所以迅速成為享有較高國際聲譽的著名大學之一,主要就是因為她培養(yǎng)出了一大批德才兼?zhèn)涞膬?yōu)秀畢業(yè)生。他們志向高遠、基礎扎實、綜合素質高、創(chuàng)新能力強,在國內(nèi)外科技、經(jīng)濟、教育等領域做出了杰出的貢獻,為中國科大贏得了“科技英才的搖籃”的美譽。2008年9月,胡錦濤總書記為中國科大建校五十周年發(fā)來賀信,信中稱贊說:半個世紀以來,中國科學技術大學依托中國科學院,按照全院辦校、所系結合的方針,弘揚紅專并進、理實交融的校風,努力推進教學和科研工作的改革創(chuàng)新,為黨和國家培養(yǎng)了一大批科技人才,取得了一系列具有世界先進水平的原創(chuàng)性科技成果,為推動我國科教事業(yè)發(fā)展和社會主義現(xiàn)代化建設做出了重要貢獻。據(jù)統(tǒng)計,中國科大迄今已畢業(yè)的5萬人中,已有42人當選中國科學院和中國工程院院士,是同期(自1963年以來)畢業(yè)生中當選院士數(shù)最多的高校之一。其中,本科畢業(yè)生中平均每1000人就產(chǎn)生1名院士和七百多名碩士、博士,比例位居全國高校之首。還有眾多的中青年才俊成為我國科技、企業(yè)、教育等領域的領軍人物和骨干。在歷年評選的“中國青年五四獎章”獲得者中,作為科技界、科技創(chuàng)新型企業(yè)界青年才俊代表,科大畢業(yè)生已連續(xù)多年榜上有名,獲獎總人數(shù)位居全國高校前列。

內(nèi)容概要

聚合物是通過化學鍵將小分子連接起來而形成的長鏈狀大分子。由這種分子聚集形成的固體材料具有多層次的物質結構,這些結構會影響摻雜其中的各種功能基團的性質。本書將具有不同結構的稀土摻雜聚合物作為研究對象,從理論和實驗的角度對這些聚合物進行了光譜分析、摻雜基質結構設計、發(fā)光性質與各層次結構的關系以及光量子調控等多方面的研究,包括各種新穎結構的設計和由其產(chǎn)生的各種特異性質。其中光量子調控是迅速發(fā)展的寬帶通訊領域的關鍵技術,相應的基礎和應用基礎研究已形成一個由聚合物科學和光子學交叉而成的新興學科——光子學聚合物科學。書中介紹的發(fā)光調控、三維光學存儲和稀土摻雜聚合物光纖的光放大性質等均為光子學聚合物領域的最新進展。雖然本書是非常專業(yè)的學術專著,但是通過閱讀,讀者也能從中了解這一新興交叉學科的概況。書中還列出了相關原始文獻以滿足感興趣的讀者進一步了解相關內(nèi)容的需要。
