Theoretical Description of the Third Order Parametric Wave Mixing in a Gas-Filled Capillary of Femto-Second Laser Pulse

The theoretical signal-pressure curves are calculated from approximate analytical solutions of the coupledequations describing the third order parametric wave mixing in a gas-filled capillary of femto-second laser pulses. Thecomparison with the corresponding experimental curves suggests that the following three factors exert important influ-ences on the degree of fitting between the theoretical and experimental results: the walk-off, the phase modulation, andthe third order harmonic of idler pulse.     

二端子有源矩阵LCD研究进展

首先介绍了传统的各种类型的二端子有源矩阵液晶显示的工作原理、结构和制作工艺。进而介绍了一种优于传统二端子模式的Lechner二极管有源矩阵液晶显示模式，并介绍了此模式的工作原理、研究现状、研究意义及发展态势．传统二端子模式都存在各自的缺点，不能很好地满足AM-LCD对于二端子器件的要求，用于AM-LCD都无法很好地达到预期目的。而Lechner二极管有源矩阵液晶显示模式，相对于其他二端子模式，只需使用二极管的正向特性，对阈值电压的要求降低，工艺更简单，图像显示质量更好，并且较易实现大屏幕显示。在目前TFT-LCD处于主导地位的情况下，通过对二端子有源矩阵液晶显示，特别是Lechner二极管二端子有源方式的研究，也许在不远的将来，实现降低AM-LCD生产线成本，简化大屏幕AM-LCD制作工艺将不是梦想。

Enhancement of Overall Photovoltaic Efficiency by Changing the Position of the Attaching Group -RSO3- on the Hemicyanine Dye Molecules

A new photoresponsive D-π-A dye, mPS, has been designed and synthesized.Compared to the parent dye PS, IPCE values in the region from 400 nm to 560 nm was greatly improved upon changing the attaching group from the p- position to the o- position of the π-conjugation bridge. A solar cell based on mPS generated a remarkably high overall yield η of 5.4% under irradiation of 80.0 mW cm^-2 white light from a Xe lamp, Compared with PS, the overall yield η increased by 64%.     

Wey1代数中的消元法与q恒等式（英）

For the algorithmic proof of q-proper-hypergeometric identities, H.Wilf and D.Zeiberg gave a theoretical frame work. In [1], they proved that q-proper-hypergeometric terms satisfy recurrence relations with polynomial coefficients and could obtain quite explicit bounds for the order of such a recurrence. But how can we find the recurrence relations?We consider single-variable q-proper-hypergeometric identities based on Zeilberg's basic idea. To find the recurrence relations, an elimination in the non-commutative Weyl algebra has been developed. Thereby we obtained the algorithm of proving single-variable q-proper-hypergeometric identities.
