序言

色谱柱是色谱分离分析的“心脏”，液相色谱技术的每一次重大进展都与分离固定相的突破密切相关。如上世纪70年代末期高效液相色谱技术的建立和90年代初期“灌流色谱”（Perfusion Chromatography）的发展都是基于多孔硅胶和“穿透孔”分离固定相的发展。近年来，基于特殊孔结构的1．5～2．0μm高强度复合材料的制备成功地催生了超高效液相色谱（UPLC）分离技术，而整体柱材料作为新一代的分离介质，已成为色谱领域广泛研究的前沿课题之一，并已经在样品预处理、手性分离、生物分离分析等领域获得十分广泛的应用。我国色谱研究工作者在多孔硅胶固定相、手性分离固定相、亲和色谱固定相和整体柱固定相等研究领域都取得了重大的进展，有些方面的研究工作已达到或领先于国际先进水平。     

序言

化学科学起源于对化学现象的整理和对比,化学(χημεια, chemeia)一词最早出自希腊作者苏达斯编著的词典,意为制取金和银的技艺,希腊人相信可以凭技艺制取金和银,并将其称为“化学”。化学的发展经历了从宏观到微观,从描述到推理,从定性到定量,从静态到动 态,从分化到综合,从古老的炼金术到19世纪的化合价理论,再到20世纪的周期律及原子结 构的现代化学演变过程。现代化学主要在分子、原子层面,研究物质的组成、性质、结构以及变化规律。     

序言

国家自然科学基金委员会化学部于1993年4月5日至10日在长沙市湖南大学主持召开“分析化学计量学研讨会”,检阅基金委对化学计量学学科基金资助项目的研究进展和成果。应会议要求,本刊在本期特刊出“分析化学计量学论文”专栏,登载该资助学科的部分最新研究成果论文,并请国家自然科学基金委员会化学部分析与环境化学学科为专栏撰写了序言。相信这些论文的发表将对推动分析化学学科的基础理论建设和促进化学计量学这一新兴学科在我国的迅速发展起到良好的作用。     

PREFACE

正Metal-catalyzed polymerization is being widely used in the controlled synthesis of various polymers.As a matter of fact,metal catalysts(both transition metal complexes and main group metal complexes)are ubiquitous and indispensable in numerous polymerization reactions,including metal-catalyzed olefin polymerization and olefin/polar monomer insertion copolymerization,ring-opening metathesis polymerization,metathesis polymerization or cyclopolymerization of α,ω-diolefins,     

PREFACE

正We are delighted to present this special themed topic of Chinese Journal of Polymer Science(CJPS) devoted to the recent advances in reversible deactivation radical polymerization(RDRP). RDRP has been widely recognized as one of the most important synthetic methods for polymers, allowing access to well-defined polymeric materials with predictable molecular weight, controlled dispersity, and tailor-made architecture. Since its discovery,     

PREFACE

Polymer electronics are one of the most active research areas in material science,information science and energy science,because it can offer new ways to create a new generation of large area,flexible and low cost electronics.For example,a voltage is applied to a polymer,which can emit light such as RGB three primary color for full color PLED (Polymer Light-emitting Diodes),even white light for white PLED.In turn,light is absorbed by a polymer to produce electric current,thatis,polymer solar cells (PSCs).     

PREFACE

The great discoveries of olefin polymerization catalysts by Karl Ziegler and Gulio Natta in 1953 founded the base of modem polyolefin industry, one of the most important fields of polymer materials. In recent years, polyolefin industry and applications of polyolefin in Asian regions have experienced a faster growth than the other parts of the world.Meanwhile,polyolefin related scientifc researches and technical innovation are also
