电子俘获型红外上转换屏

利用溶液悬浮分层提取技术获得粒度较为一致的电子俘获材料（ＥＴＭ）粉末，考虑ＥＴＭ屏空间分辨率、红外→可见发光亮度、ＥＴＭ化学稳定性和膜层均匀性等主要因素，采用不同方法制作了ＥＴＭ屏，较好地解决了ＥＴＭ膜层均匀性及器件封装后的化学稳定性等问题，并通过测试比较，提出了一种兼顾空间分辨率和红外上转换发光亮度的微镶嵌屏制作技术方案．     

杂质对KDP晶体光学质量的影响

 研究了几类可能出现在KDP晶体的生长溶液中的有机物杂质和无机阴离子杂质基团对KDP晶体散射、透过率、光损伤阈值等光学质量的影响，结果表明，不同种类的杂质的影响并不相同，造成这一结果的根本原因在于杂质离子的结构及其与晶体表面原子成键能力的不同。     

Synthesis and Catalytic Application of Chiral 1, 1-Binaphthyl Polymers

Polymer-supported reagents and catalysts have attracted considerable attention as they offer alternative methods to separate and reuse expensive and often toxic chemicals1. Traditionally, the polymer-supported chiral catalysts are prepared by anchoring highly enantioselective monomeric catalysts to flexible and sterically irregular polymer supports. Because of the stereo-irregularity and flexibility of the traditional polymeric chiral catalysts, their catalytic sites do not have well-defined…

细菌视紫红质近场光存储特性的研究

结合近场光学显微镜，利用菌紫质M态和基态之间的跃迁，对BR—D96N样品作了静态近场光存储特性的研究。结果表明，近场区域内细菌视紫外质在光激发前后对红光的吸收有较大差别，而且激发后无光照时会缓慢弛豫到激发前的状态，具有光致变色特性和热弛豫特性，可望作为近场光存储材料和微光学信息处理器件材料。

A Quantum-Mechanical Explanation of Buffer Gas Effect on Submillimeter Wave Laser

Based on the theory of molecular vibration relaxation, the model of buffer gas effect was built up. By theoretically deducing the vibrational lower-level deactivation rate of operating gas molecule with quantum mechanics, the selection rules of high-efficient buffer gas under different working conditions were educed and tested by experiments. The results could be helpful to the study of large-power wide-range efficient tunable miniature pulsed optically pumped submillimeter wave laser and its application.     

改进型氢氧联合循环及其性能初步分析

1前言氢能既具备矿石燃料的优点，又符合长远能源发展的要求，被称为21世纪的能源。氢能发电是氢能利用的一个重要方面，近年来出现了各种氢能发电方案。文献山提出了氢氧联合循环（包括混合式和面式）；此外还有高温蒸汽朗肯循环，氢氧燃烧，加热氦（或二氧化碳）的闭式透平K’］；对燃用液氢的系统也有论述＊’］。本文在已有工作的基础上，综合了混合式和面式氢氧联合循环的一些特点，提出了氢氧联合循环的改进型式。本文将着重讨论这种改进循环的性能，并与混合式多级再热氢氧联合循环加以比较，对氢氧联合循环的进一步发展作一初步尝…
