一、名词解释：1、Surveying (测量学）is the art of making such measurements of the relative positions of points on the surface of Earth that,on drawing them to scale natural and artificial features may be exhibited in their correct horizontal or vertical relationships.2、Plane surveying （平面测量)is of wide scope and utility,and its methods are e mployed in the vast majorit y of surveys undertaken for various purposes,such as en gineering ,architectural,legal,c ommercial,scientific,geograph ical,exploratory,military,and n avigational.3、Geodetic surveys（大地测量）are usually of a nati onal character,occasionally w orks of international coopera tion,and they are undertaken as basis for the production of accurate maps of wide areas.4、Leveling（水准测量) is t he general term applied to a ny of the various processes by which elevations of point s or differences in elevation are determined.5、The theodolite （经纬仪）is an instrument designed for the measurement of hori zontal and vertical angles.It is the most precise instrume nt available for such observ ations,and is of wide applica bility in surveying.6、A traverse（导线）is a series of consecutive lines whose lengths and directions have been determined from field measurements7、Traversing(导线测量）,the act of establishing traverse stations and making the ne cessary measurements,is one of the most basic and wid ely practiced means of deter mining the relative locations of points.8、Azimuths（方位角）are measured clockwise from th e north end of the meridian through the angle points. 9、Topographic surveys（地形测量）are made to deter mine the configuration (relie f) of the earth’s surface and to locate natural and cultur al features on it.10、A topographic map（地形图）is a large scale repres entation of a portion of theEarth’s showing culture, relief, hydrography, and perhaps vegetation.11、Systematic-Error(系统误差）:These-errors conformto mathematical and physical laws.Their magnitude maybe constant or variable depending on conditions.12、Radom error(偶然误差）：These are errors that remain after mistakes and systematic errors have been eliminated.13、Precision(精度)refers to the degree of refinementor consistency of a group of measurements.14、Accuracy(准确度）which denotes the absolute nearness of measured quantities to their true values.二、填空1、The metal case is attached to some part of the instrument in such a way as topermit some (adjustment) of the position.2、Transits,are instrumentswhich ..... Along the verticalplane (altitude) as well asthe horizontal plane (azimuth).3、These instruments are (tripods),plane tables,(level rods),chains,and (tapes).4、As can be observed ,EDM systems are made up ofthree components-(a transmitter),(a reflector),and (a receiver).5、....the telescope must becapable of rotation about a(horizontal axis),for measurement of horizonal angles,the instrument must be rotatedabout a (vertical axis).6、There must be an (indexmark) on the rotating part,placed so that readings canbe taken against it on the(graduated circle).7、.....the observer operatesa setting device to obtain a(mean reading) free from(eccentricity error).8、If the (plumb bob) is not over the point,the (centering screw) can be loosenedand the.......9、These notes include directions.....stations with (fourdifferent positions).Two readings were taken on each position (one with the telescope normal or direct and onewith the instrument (reversed or plunged)).10、The line is determinedby a telescope with the usual components consisting of(object glass),(focusing arrangement),(diaphragm withcross-lines), and (eye-piece).11、A level fitted with (horizontal circle) and (stadia lines) can be used to make acomplete (three-dimensional) survey of a limited area round the instrument.12、Levels are used to obtain the direct measurement of （height differences）between two points.13、Which transmit either (modulated laser) or (infrared light) having wavelengths within or slightly beyondthe ......14、Which transmits (microwaves) with (frequencies) in the range of 3 to 35GHZcorresponding to wavelength of about 1.0 to 8.6 mm.15、The methods used in measuring angles or directionsof traverse lines vary,and include (compass bearings），（interior angles),(deflection angles),(angles to the right),(azimuths).16、The instrument is oriented at each station by (backsighting) on the previous point with （the back bearingset) on the plates.17、(Electronic devices) and (taping) are used most often and provide the highestorder of accuracy.18、On construction work,(allowable limits of closure)depend on the use and extent of the traverse and typeof project.Bright location, for example ,demands a highdegree of precision.19、Vertical control is provided by bench marks in or near the tract to be surveyed.It becomes the foundation for correctly portraying reliefon a map,A （vertical control net)is established by (lines of levels）starting fromand closing on bench marks.三、翻译：1、It is convenient to considerthat a bubble tube has anaxis,which may be taken as astraight line parallel to the freesurface of the liquid when thebubble is in the centralposition determined by thegraduation marks.当气泡处于分划线所确定的中心位置时，我们可以很容易想像水准管有一个轴，这个轴可以看作是一条与液体的自由表面平行的直线。
