纽约，天堂与地狱的诱惑

如果你爱一个人,送他去纽约,因为那里是天堂;如果你恨一个人,送他去纽约,因为那里是地狱。对很多人来说,纽约就是一个梦,一个关于拼博与激情的梦,一个关于青春与创造的梦。那里创造了无数的财富神话和造星童话。纽约,是个容纳梦想的地方,只要有梦     

咖啡梦，二三事

Tree Coffee——小小弄堂里的春天The reason why I love here lies in the fact that there is much private coffee here.I also love coffee with wine here.But what I love most is orange cappuccino here.Will spring be far if winter comes?去Tree是一个初冬午后,骤然降温的空气带来一场绵绵冬雨,武康路上的梧桐已经被风吹得叶落一地。天空和地面都是斑驳的,一幢幢老式西洋小楼静默沉稳,暗红墙面却带着一丝阳春的暖意。一个小小的院落入口安静地开在拐角处,不说话。这个地段常见的一些异域面孔带着红晕进进出出,神情安详。从窄窄的入口走进去,是一个类似北京     

杭州，那一叶心上的舟

未能抛得杭州去,一半勾留是西湖。杭州的杭字,作名词在古文里有方舟的意思。据说,杭州的杭字,便是源于公元前21世纪,夏禹南巡,大会诸侯于会稽山,途经杭州之地舍航登陆时留在岸边的那条船。可能从那时起,杭州这个地方,就与船,分不开了。且不去说在春秋末期,吴越两国的众将士是如何"以船为车,以楫为马"进行着那     

夏日，枇杷记

正周末,我是偶尔去菜场时,看到的那一枚枚金黄色的小小枇杷。如此诱人,诱使我不由自主地开了口。"老板,这枇杷怎么卖?"摊主是位年约五旬的男子,微微一笑说:"25块一斤。"又说,"正宗的绿色枇杷,你看这个儿,小小的,和市场上卖的不同,那些都用了药水才长大的……"

苏州评弹，“中国最美的声音”

苏州评弹的表演分为说、噱、弹、唱四部分,是盛行于江南一带的地方曲艺,系评话和弹词的总称。她起源于风景秀丽的苏州,故演出均操吴语,约有四百年历史,被誉为江南奇葩。评话又称大书,有说无唱,演出大都为单档(一人),演员凭一把折扇,一块醒木,边说边演,     

南京城，一直延续着的记忆

要写这样的一个城市,实在是一个太过宽泛的命题,几千年的光阴荏苒,多少代的风流辈出,怎么能够在一篇千字小文里描述殆尽?要说的,杜牧、刘禹锡们早已都说过了。且自换种心情,只说说我眼里的那个南京,相信他们也不以为过了吧。

Triton, Pluto, Centaurs, and Trans-Neptunian Bodies

The diverse populations of icy bodies of the outer Solar System (OSS) give critical information on the composition and structure of the solar nebula and the early phases of planet formation. The two principal repositories of icy bodies are the Kuiper belt or disk, and the Oort Cloud, both of which are the source regions of the comets. Nearly 1000 individual Kuiper belt objects have been discovered; their dynamical distribution is a clue to the early outward migration and gravitational scattering power of Neptune. Pluto is perhaps the largest Kuiper belt object. Pluto is distinguished by its large satellite, a variable atmosphere, and a surface composed of several ices and probable organic solid materials that give it color. Triton is probably a former member of the Kuiper belt population, suggested by its retrograde orbit as a satellite of Neptune. Like Pluto, Triton has a variable atmosphere, compositionally diverse icy surface, and an organic atmospheric haze. Centaur objects appear to come from the Kuiper belt and occupy temporary orbits in the planetary zone; the compositional similarity of one well studied Centaur (5145 Pholus) to comets is notable. New discoveries continue apace, as observational surveys reveal new objects and refined observing techniques yield more physical information about specific bodies.     

加快维修周转时间

大到整个飞机机身,小到某个飞机附件,周转时间都是十分重要的。在成本、质量和速度的三角关系中,后者正在占据越来越重要的地位。现在航空业出现一种新趋势,即航空公司在寻找维修公司时更注重维修周转时间的长短,以前,却是更为注重维修价格的高低。随着飞机营运费用的升高,周转

维修数据传输:更快速、更廉价、更好

一直以来,航空公司大多采用ACARS通信系统(飞机通信寻址和报告系统)进行空中通信服务.但与陆地通信系统相比,该系统的传输速度慢而且成本高,成为目前影响飞行数据传输速度的重要因素之一.一些MRO软件供应商已开始开发机载无线通信系统,试图改善以往缓慢、昂贵和复杂的空中无线服务,使飞行中生成的重要维修数据以更低的成本、更快的速度和更高效率实现传输.

Ion engine grids: Function,main parameters,issues, configurations,geometries, materials and fabrication methods

Ion optics are crucial components of ion thrusters and the study of the different ion extraction solutions used since the beginning of the electric propulsion era is essential to understand the evolution of ion engines. This work describes ion engine grids' main functions, parameters and issues related to thermal expansion and sputter erosion, and then introduces a review of ion optics used for significant launched and tested ion thrusters since 1970. Configurations, geometries, materials and fabrication methods are analyzed to understand when typical ion thrusters use two or three grids, what are the thicknesses and aperture sizes of the screen, accelerator and decelerator grids, why molybdenum and carbon-based materials such as pyrolytic graphite and carbon–carbon are the best available options for ion optics and what is the manufacturing method for each material.     

CIR Morphology, Turbulence, Discontinuities, and Energetic Particles

Corotating interaction regions (CIRs) in the middle heliosphere have distinct morphological features and associated patterns of turbulence and energetic particles. This report summarizes current understanding of those features and patterns, discusses how they can vary from case to case and with distance from the Sun and possible causes of those variations, presents an analytical model of the morphological features found in earlier qualitative models and numerical simulations, and identifies aspects of the features and patterns that have yet to be resolved. This revised version was published online in August 2006 with corrections to the Cover Date.
