光锥与TDI-CCD耦合监控中测试目标的一种实现方法

为了给光锥与时间延迟积分电荷耦合器件耦合监控装置提供有效的被测运动条纹，分析了传统推扫成像实验装置的不足之处，设计了电子显示目标滚屏运动装置.采用光学相机对印刷条纹静止成像，并用TDI-CCD数字相机对监视器屏幕上的运动条纹动态成像.实验结果表明，该方案解决了高分辨率的鉴别率图样无法在监视器或投影仪上精确显示的困难.与传统的实验室模拟装置相比，该方案提高了鉴别率条纹的运动稳定性，减小了条纹运动速率与TDI-CCD扫描行频间的失配误差，不仅能够对耦合过程实施监控，而且还能用于耦合系统的像质评价.     

"电动势"教学难点的突破

电动势是中专物理教材“恒定电流”中的一个重点概念，又是学生难以理解的难点内容．电动势描述了电源内部非静电力移动电荷做功的能力大小，在教学中学生对电源、电动势、电压之间的关系很容易混淆，对电源能持续向外供电的原因不理解，特别是对电源内部由于非静电力搬移电荷做功，使电源两极间保持恒定电势差的事实无法体会，同时，也很难利用实验做到让学生直观、形象地认识，因此形成了教学难点．鉴

Scanning mirror on a vibrating membrane for dynamic optical trapping

A study of the variation of the spectral shape and the harmonic distribution of the high-order harmonics generated from silver plasma on the frequency chirp of the driving laser radiation (793 nm 48 fs) is reported. The results of the systematic study of the harmonic generation from the 21st order up to the 61st order (λ=13 nm) are presented. A tuning of the harmonic wavelength up to 0.8 nm can be accomplished by variation of the laser chirp. PACS 42.65.Ky; 42.79.Nv; 52.38.Mf     

铁羰基络合物制备的一氧化碳加氢催化剂的研究

本文采用Ｆｅ＿３（ＣＯ）＿（１２）制备担载型络合物催化剂。采用程序升温反应技术考察了这类催化剂（ＣＯ＋Ｈ＿２）的反应性能，井使用紫外漫反射光谱和穆斯堡尔谱对催化剂进行了表征。经２５０℃和１５０℃还原的Ｆｅ／γ－Ａｌ＿２Ｏ＿３催化剂不仅活性远远高于４５０℃还原的Ｆｅ／γ－Ａｌ＿２Ｏ＿３，而且前者在反应过程中有乙烯和乙烷生成，后者则只有甲烷生成。经２５０℃还原的Ｆｅ／分子筛催化剂的活性高于４５０℃还原的Ｆｅ／分子筛催化剂，而且前者在反应过程中有乙烯、乙烷和丙烯生成，后者则只有甲烷生成。紫外漫反射谱和穆斯堡尔谱结果表明：较温和条件下活化的催化剂上有金属于属键骨架的存在。     

Synthesis,crystal structures and electrochemical properties of group 6 metal carbonyl anion complexes

A series of [M(CO)₅I]⁻ and [M₂(CO)₁₀I]⁻ anion complexes have been synthesized by the photochemical reaction of PhCH₂N(CH₃)₃I or FcCH₂N(CH₃)₃I (Fc=ferrocenyl) with M(CO)₆ (M = Cr, Mo or W), and characterized by elemental analyses, i.r., ¹H-n.m.r. and ¹³C-n.m.r. spectra in the case of the molybdenum and tungsten complexes. These complexes exhibit considerably different electrochemical behavior, when investigated by cyclic voltammetry. The crystal structures of [PhCH₂N(CH₃)₃][Cr(CO)₅I] and [FcCH₂N(CH₃)₃][W₂(CO)₁₀I] have been determined by X-ray diffraction, indicating that only weak contacts maybe exist between anions and cations by the I...H bond in the former, and there are no direct interactions between anions and cations in the latter.     

Fabrication of hexaphenylsilole nanowires and their morphology-tunable photoluminescence.

Immersion of nanoporous alumina membranes into saturated solutions of hexaphenylsilole with subsequent solvent evaporation affords aligned organic nanowires. The luminescent properties of the hexaphenylsilole nanowires can be manipulated by varying their morphologies, which were controlled by changing the channel sizes of the alumina templates.
