This paper precisely conducts the special topic research in view of some important technologies of the digitized control module.(1) AC motor control circuit of PAN/TILT is designed ,which speed is controlled by AT89C51 MCU. DC motor control circuit of LENS is designed too.(2) The hardware and software of automatic temperature control is designed, which used in camera protect box without A/D IC. A kind of single wire communication IC is used in the circuit. So, the program is given.(3) A method of video switch without picture shock is discussed in this paper, and 16x8 video switch circuit is designed. AT89C51 can carry out time sequence logical control with the sync signals by request..(4) The module of real-time clock is designed, in which, LCM is used, a kind of three-wire communication IC is used too.

Its universality: its democratic equality and constancy to its nature in seeking its own level: its vastness in the ocean of Mercator's projection: its unplumbed profundity in the Sundam trench of the Pacific exceeding 8000 fathoms: the restlessness of its waves and surface particles visiting in turn all points of its seaboard: the independence of its units: the variability of states of sea: its hydrostatic quiescence in calm: its hydrokinetic turgidity in neap and spring tides: its subsidence after devastation: its sterility in the circumpolar icecaps, arctic and antarctic: its climatic and commercial significance: its preponderance of 3 to 1 over the dry land of the globe: its indisputable hegemony extending in square leagues over all the region below the subequatorial tropic of Capricorn: the multisecular stability of its primeval basin: its luteofulvous bed: its capacity to dissolve and hold in solution all soluble substances including millions of tons of the most precious metals: its slow erosions of peninsulas and islands, its persistent formation of homothetic islands, peninsulas and downwardtending promontories: its alluvial deposits: its weight and volume and density: its imperturbability in lagoons and highland tarns: its gradation of colours in the torrid and temperate and frigid zones: its vehicular ramifications in continental lakecontained streams and confluent oceanflowing rivers with their tributaries and transoceanic currents, gulfstream, north and south equatorial courses: its violence in seaquakes, waterspouts, Artesian wells, eruptions, torrents, eddies, freshets, spates, groundswells, watersheds, waterpartings, geysers, cataracts, whirlpools, maelstroms, inundations, deluges, cloudbursts: its vast circumterrestrial ahorizontal curve: its secrecy in springs and latent humidity, revealed by rhabdomantic or hygrometric instruments and exemplified by the well by the hole in the wall at Ashtown gate, saturation of air, distillation of dew: the simplicity of its composition, two constituent parts of hydrogen with one constituent part of oxygen: its healing virtues: its buoyancy in the waters of the Dead Sea: its persevering penetrativeness in runnels, gullies, inadequate dams, leaks on shipboard: its properties for cleansing, quenching thirst and fire, nourishing vegetation: its infallibility as paradigm and paragon: its metamorphoses as vapour, mist, cloud, rain, sleet, snow, hail: its strength in rigid hydrants: its variety of forms in loughs and bays and gulfs and bights and guts and lagoons and atolls and archipelagos and sounds and fjords and minches and tidal estuaries and arms of sea: its solidity in glaciers, icebergs, icefloes: its docility in working hydraulic millwheels, turbines, dynamos, electric power stations, bleachworks, tanneries, scutchmills: its utility in canals, rivers, if navigable, floating and graving docks: its potentiality derivable from harnessed tides or watercourses falling from level to level: its submarine fauna and flora, numerically, if not literally, the inhabitants of the globe: its ubiquity as constituting 90 percent of the human body: the noxiousness of its effluvia in lacustrine marshes, pestilential fens, faded flowerwater, stagnant pools in the waning moon.

50它的普遍性，它的民主的平等性，以及保持着它自身求平的本质。用墨卡托投影法在地图上所标示出的浩淼的海洋；太平洋中巽他海沟那超过八千噚的不可测的深度；永不消停、后浪推前浪地冲刷着海岸线每一部位的波涛以及水面上的微粒子；水的单位粒子的独立性；海洋变幻莫测；根据液体静力学，风平浪静时它纹丝不动；根据液体动力学，小潮大潮时它便涨了起来。暴风雨后一片沉寂；北极圈与南极圈冰冠地带的不毛性以及对气候及贸易的影响；跟地球上的陆地相比占三对一优势；它在亚赤道带南回归线以南的整个区域延伸无数平方海里的绝对权威；其在原始海盆里数千万年以来所保持的稳定性；它那橙红色海床；它那把包括数百万吨贵金属在内的可溶解物质加以溶解，并使之保持在溶解状态的性能；它对半岛和有下陷趋势的岬角所产生的缓慢的浸蚀作用；其冲积层；其重量、容积与浓度；它在咸水湖、高山湖里的静谧；其色调因热带、温带和寒带而变为或浓或淡；与陆上的湖泊、溪流及支流汇合后注入海洋的河川，还有横跨大洋的潮流所构成的运输网。沿着赤道下面的水路自北向南的湾流；海震、水龙卷、自流井、喷泉、湍流、漩涡、河水暴涨、倾盆大雨、海啸、流域、分水岭、间歇泉、大瀑布、漩流、海漩、洪水、泛滥、暴雨等滥施淫威；环绕陆地的上层土壤那漫长的曲线；源泉的奥秘可用探矿杖来占卜或用湿度测定器来揭示；阿什汤大门的墙壁上的洞、空气的饱和与露水的蒸发能够证明那潜在的湿度；水的成分单纯，是氢二、氧一的化合物；水的疗效；水的死海里的浮力；它在小溪、涧谷、水坝的缝隙、船舷的裂口所显示的顽强的浸透性；它那清除污垢、解渴、灭火、滋养植物的性能；作为模范和典型，它的可靠性；它变化多端：雾、霭、云、雨、麦、雪、雹；并在坚固的消防龙头上发挥出压力；而且千姿百态：湖泊、湖岔、内海、海湾、海岬、环礁湖、环状珊瑚岛、多岛海、海峡、峡江、明奇、潮汐港湾、港湾；冰河、冰山、浮动冰原显示出它是何等坚硬；在运转水车、水轮机、发电机、发电厂、漂白作坊、鞣皮厂、打麻厂时，它又是那样驯顺；它在运河、可航行的河川、浮船坞和干船坞所起的作用；潮汐的动力化或利用水路的落差使它得以发挥潜力；海底那些成群的动物和植物虽然并非名副其实地栖息在地球上，论数目却占地球上生物的一大半；水无所不在，占人体的百分之九十；在沼泽地、闹瘟疫的湿地、馊了的花露水以及月亏期那淤积污浊的水塘子，水所散发的恶臭充满了毒气。

While it is randomly grabbing around with rage, the dragon god flits to the proximity of its feet and inserts four inverse claws into the skin of it (there are three straight claws and one inverse claw to form a whole dragon claw).

天魔出招越来越是混乱急躁，雷鞭如雨般向龙神击去，但龙神在其中滑溜地穿梭，很快又一爪抓瞎了它好几只眼，然后一尾打在它另外几只眼上，趁它愤怒乱抓之时，飞到了它足部附近，将四支倒爪刺入天魔外皮(每只龙爪有三支正爪一支倒爪)，然后一边绕著它飞，一边往上升，於是天魔身上就被抓出四道螺旋状的深深爪痕，等飞到天魔头部，龙神放开四爪，随著一声长啸往九天之上翔去，瞬时天魔头顶就出现一个直通九天的大洞，从洞中吹下的虚空旋风将天魔皮肉从爪痕处撕裂，重归暗云，从天空落下

The author of this paper participated the beginning phase of the whole Yun-Wan freeway geological exploration work. After lucubrating GIS exploitation technique and reading plenty of correlative references the author realized that geological data management is of practical value to engineering project department. Thus, thanks to those profound data accumulated during previous explorations, the author developed a professional and practical GIS system for Yun-Wan freeway—EGIS based on exploitation flat roof - Arc View.

作者参与了云万高速公路的整个地质初勘阶段的工作，在深入学习了GIS开发技术和在查阅大量相关参考文献的基础上，并了解了工程设计部门对地质资料管理的实际需求，将工作中所收集到的大量地质勘察资料作为基础源数据，在ArcView GIS的开发平台上，针对云万高速公路开发出了专业型的实用GIS系统——工程地质资料管理信息系统，系统由Access关系数据库管理系统建立属性数据库，由ArcView GIS软件来实现对空间数据库的管理功能；以软件本身所提供的Avenue语言和程序设计语言Visual Basic 6.0作为系统的开发语言，并对ArcView GIS软件本身的不足方面，进行了二次开发，使系统的功能得到了增强，让系统使用起来更加方便和完善。

It is He Who sendeth the winds like heralds of glad tidings, going before His mercy: when they have carried the heavy-laden clouds, We drive them to a land that is dead, make rain to descend thereon, and produce every kind of harvest therewith: thus shall We raise up the dead: perchance ye may remember.

他使风在他的慈恩之前作报喜者，直到它载了沉重的乌云，我就把云赶到一个已死的地方去，于是，从云中降下雨水，于是借雨水而造出各种果实--我这样使死的复活--以便你们觉悟。

On both sides of the head, bo palletizer gables and jump out after all, coping with brick and WaiHu bolts into the curve, delicate and elegant, In front of the hall YanXia is WangZhuan grinding and Chuan bent with very precise porch corridor, look up, its monumental made by artificial and materials that, And the bridge of short column and column, is not a simple shu to use a few short wood, but installation high-relief curving flowers.the curving flowers and leaves, Lu carved into a cloud, LiangYun fog, not only can satisfy the structural component of the requirements, and the proper decoration, try and do not provide craftsmanship.

两侧山墙的垛头、博缝及后檐出跳，也都用砖磨成道道内、外弧的曲线，精致而又素雅；厅屋前檐下是把望砖磨成与弯椽配合得极为精确的轩廊，抬头望去令人赞叹不已，其制作所耗费的人工和材料可想而知；还有那梁架上的短柱与蜀柱部位，不是简单地用几根短木，而是安装高浮雕和透雕雕刻成荷叶墩、栌斗、山雾云、抱梁云构件，不仅能满足结构上的要求，又恰到好处的进行了装饰，真可谓两全齐美，别具匠心。

Such low-level clouds, called stratus clouds, occur below 6,500 feet (2,000 meters) and often bring rain or snow.
