捕捉都市人物——穿行于石屎森林的摄友（二）

笑脸，失神，本能反应，每种固定的表情或行为，在城市狡黠的光影下，会表现出多种层面的生活含义。努力抓住一些迅速消逝在眼睛里的面目和动作，试图表现出这些平凡的动作中触目惊心的一面，行色匆匆的人群，匆忙的脚步，孤独的背影，拥堵的车辆。繁华的闹市，这些东西，在没有时间记录的时刻，记录下这个城市不可缺少的经历的一个个画面，我感到异乡的孤独、亲切，它们构成了这个城市不可缺少的经历的一个个画面，我感到在异乡的孤独、亲切，它们构成了这个城市的身体部分。我在道路上抓拍，各式各样的身影档案凝固成它的血脉，画面之外的有声部分成为它的传奇，城市的庞大和多元化，使我无法根据我的主观感受对她做出全面的描述，但是，新的有生命感受，在喧哗中悄然显影。     

新酷家电

立体支架，让人坐下就不想起来的按摩椅，寄予厚望，好梦常在，童话电影院，自己在家做面条，钉书器军刀，安全的无线网络，会转弯的声音，我的移动电视梦，最廉价的法拉利感觉，真正的打机。     

关怀以音乐为本 音乐是心灵妙药

月有圆缺，人有离台，中秋月圆，人间并非家家团圆，悲欢离台，亦难避免．更难避免的是人间苦难，年来大自然的天灾，和人谋不臧引发的人祸，更是越来越严重。大大小小的天灾人祸，确已是无日无之，你我今日或许碰不上，亦往往会有周边的亲朋不幸遇上。撤除天灾人祸，人生必定难免的是生老病死，此一过程亦难免会为人带来情绪上的起伏。为此，在社会上，特别是一些宗教团体，     

风云际会话平板——液晶(LCD)、等离子(PDP)、背投(RPTV) 电视现状杂谈

北京08奥运在即，城镇家居环境营造水平的升级，催生着新生代电视，淘汰着老态龙钟的CRT（玻壳电视机）。然而，新生代并非只有唯一的继承者，出现了三分天下的局面，即液晶（LCD），等离子（PDP），背投（RPTV），经过几年来市场的敖斗和洗礼，天平逐渐向液晶（LCD）倾斜，虽然等离子（PDP），背投（RPTV）亦拥有强大的技术优势，结果显而易见，液晶（LCD）阵营因为应用面更广，积累资源更多，占据了大半江山，大有一统天下之势。但等离子（PDP），背投（RPTV）也非等闲之辈，不会轻易将大好江山拱手相让。     

音乐手机路向何方 无线音乐，下一个制高点

如今，手机厂商推出的新产品中，至少有50%以上的手机都搭载了音乐播放功能，可以说，音乐播放已经成为当今手机的一个必备功能，在苹果公司的iPhone即将上市之际，诺基亚，摩托罗拉，索尼爱立信，三星四大厂商同时大力推广其旗下音乐手机，突然之间，新一轮的音乐手机风潮再次来临，而且比以往都要更为激烈，不过，本文关注的并不是这一轮音乐手机之风，我们正在思考，在这轮音乐手机竞争过后，将会激励手机厂商们研发出什么样的更具划时代意义的音乐手机，而对于被市场广为看好的手机无线音乐市场来说，又将会得到一个什么样的进步？     

影像

电影摄影师曹郁执导的微电影《城市微旅行》片末，冯唐面对一个戴着面具的小丑，在自己面前变换着滑冰的动作。那个陌生的人物，象征的其实是另一个，或者就是本来真正的自己吗？文字和人一样，很多时候比拼的不是强，是弱。是弱弱的真，是短暂的真，是嚣张的真，好诗永远比假话少，好酒永远比白开水少。心里有灵，贴地飞行的时候，永远比坐着开会的时候少．所以大酒之后，看到女人而不是看到花朵，看到月亮而不是看到灯泡。想起你，是想起其他比你完美太多的女人。对于一个观察者来说，旅行的终极意义就在于，让你站在自己的面前，观察自己，粉碎自己，获得重生。——《城市微旅行》

Collinear phase-matching study of terahertz-wave generation via difference frequency mixed in GaAs and Inp

The collinearly phase-matching condition of terahertz-wave generation via difference frequency mixed in GaAs and InP is theoretically studied. In collinear phase-matching, the optimum phase-matching wave hands of these two crystals are calculated. The optimum phase-matching wave bands in GaAs and lnP are 0.95-1.38μm and 0.7-0.96μm respectively. The influence of the wavelength choice of the pump wave on the coherent length in THz-wave tuning is also discussed. The influence of the temperature alteration on the phase-matching and the temperature tuning properties in GaAs crystal are calculated and analyzed. It can serve for the following experiments as a theoretical evidence and a reference as well.     

Effects of the alloy compositions on the phonon-polaritons in ternary mixed crystals

Composition dependence of bulk and surface phonon-polaritons in ternary mixed crystals are studied in the framework of the modified random-element-isodisplacement model and the Bom-Huang approximation. The numerical results for Several Ⅱ - Ⅵ and Ⅲ- Ⅴ compound systems are performed, and the polariton frequencies as functions of the compositions for ternary mixed crystals AlxGa1-xAs, GaPxAS1-x, ZnSxSe1-x, GaAsxSb1-x, GaxIn1-xP, and ZnxCd1-xS as examples are given and discussed. The results show that the dependence of the energies of two branches of bulk phonon-polaritons which have phonon-like characteristics, and surface phonon-polaritons on the compositions of ternary mixed crystals are nonlinear and different from those of the corresponding binary systems.     

Influence of PVK ： NPB hole transporting layer on the characteristics of organic light-emitting devices

A doping system consisting of NPB and PVK is employed as a composite hole transporting layer （CHTL）. By adjusting the component ratio of the doping system, a series of devices with different concentration proportion of PVK ： NPB are constracted. The result shows that doping concentration of NPB enhances the competence of hole transporting ability, and modifies the recombination region of charge as well as affects the surface morphology of doped film. Optimum device with a maximum brightness of 7852 cd/m^2 and a power efficiency of 1.75 lm/W has been obtained by choosing a concentration proportion of PVK ： NPB at 1：3.     

New insert layer structure OLEDs

An insert layer structure organic electroluminescent device（OLED） based on a new luminescent material （Zn（salen）） is fabricated. The configuration of the device is ITO/CuPc/NPD/Zn（salen）/Liq/LiF/A1/CuPc/NPD/Zn（salen）/Liq/LiF/A1. Effective insert electrode layers comprising LiF（1nm）/Al（5 nm） are used as a single semitransparent mirror, and bilayer cathode LiF（1 nm）/A1（100 nm） is used as a reflecting mirror. The two mirrors form a Fabry-Perot microcavity and two emissive units. The maximum brightness and luminous efficiency reach 674 cd/m^2 and 2.652 cd/A, respectively, which are 2.1 and 3.7 times higher than the conventional device, respectively. The superior brightness and luminous efficiency over conventional single-unit devices are attributed to microcavity effect.     

Analysis of error performance on Turbo coded FDPIM

Due to variable symbol length of digital pulse interval modulation（DPIM）, it is difficult to analyze the error performances of Turbo coded DPIM. To solve this problem, a fixed-length digital pulse interval modulation（FDPIM） method is provided. The FDPIM modulation structure is introduced. The packet error rates of uncoded FDPIM are analyzed and compared with that of DPIM. Bit error rates of Turbo coded FDPIM are simulated based on three kinds of analytical models under weak turbulence channel. The results show that packet error rate of uncoded FDPIM is inferior to that of uncoded DPIM. However, FDPIM is easy to be implemented and easy to be combined, with Turbo code for soft-decision because of its fixed length. Besides, the introduction of Turbo code in this modulation can decrease the average power about 10 dBm, which means that it can improve the error performance of the system effectively.     

A method for calculating the center position of collimated light

It is a key problem to accurately calculate beam spots＇ center of measuring the warp by using a collimated laser. A new method, named double geometrical center method （DGCM）, is put forward for the first time. In this method, a plane wave perpendicularly irradiates an aperture stop, and a charge couple device （CCD） is employed to receive the diffraction-beam spots, then the geometrical centers of the fast and the second diffraction-beam spots are calculated respectively, and their mean value is regarded as the center of datum beam. In face of such adverse instances as laser intension distributing defectively, part of the image being saturated, this method can still work well. What＇s more, this method can detect whether an unacceptable error exits in the courses of image receiving, processing and calculating. The experimental results indicate the precision of this method is high.     

Preparation and Characterization of TaN ALD Precursors

High purity organic-tantalum precursors for thin film ALD TaN were synthesized and characterized.Vapor pressure and thermal stability of these precursors were studied.From the vapor pressure analysis,it was found that TBTEMT has a higher vapor pressure than any other published liquid TaN precursor,including TBTDET,TAITMATA,and IPTDET.Thermal stability of the alkyl groups on the precursors was investigated using a 1H NMR technique.The results indicated that the tertbutylimino group is the most stable group on TBTDET and TBTEMT as compared to the dialkylamido groups.Thermal stability of TaN precursors decreased in the following order:TBTDET ＞ PDMAT ＞ TBTEMT.In conclusion,precursor vapor pressure and thermal stability were tuned by making slight variations in the ligand sphere around the metal center.     

Curved crystal spectrometer for the measurement of X-ray lines from laser-produced plasmas

In order to diagnose the laser-produced plasmas, a focusing curved crystal spectrometer has been developed for measuring the X-ray lines radiated from a laser-produced plasmas. The design is based on the fact that the ray emitted from a source located at one focus of an ellipse will converge on the other focus by the reflection of the elliptical surface. The focal length and the eccentricity of the ellipse are 1350 mm and 0.9586, respectively. The spectrometer can be used to measure the X- ray lines in the wavelength range of 0.2-0.37 nm, and a LiF crystal （200） （2d = 0.4027 nm） is used as dispersive element covering Bragg angle from 30° to 67.5°. The spectrometer was tested on Shengnang- Ⅱ which can deliver laser energy of 60-80 J/pulse and the laser wavelength is 0.35 μm. Photographs of spectra including the 1 s2p ^1P1-1s^2 ^1S0 resonance line（w）, the 1s2p ^3P2-1s^2 1S0 magnetic quadrupole line（x）, the 1s2p ^3P1-1 s^2 ^1S0 intercombination lines（y）, the 1 s2p ^3S~1-1 s^2 ^1S0 forbidden line（z） in helium-like Ti Ⅹ Ⅺ and the 1 s2s2p ^2P3/2-1 s622s ^2S1/2 line（q） in lithium-like Ti Ⅹ Ⅹhave been recorded with a X-ray CCD camera. The experimental result shows that the wavelength resolution（λ/△ 2） is above 1000 and the elliptical crystal spectrometer is suitable for X-ray spectroscopy.
