光学测距仪

Modern and practical astronomy was developed in the 18th century, and successively from the theoretical and practical solution to the Sino-satellite instrument measuring time, too Seoul Scott multi-satellite measurements such as latitude, as well as simultaneous determination of longitude and latitude Supreme Court means the emergence of theodolite, contour instrument, the satellite instrument, zenith instrument, photographic zenith tube, sextant and other useful astronomical instruments, the most commonly used is the optical theodolite .20 century, all-round practical field of astronomy 60 years after the emergence of new technologies, such as satellite Dhoop Le observation and satellite laser ranging, not only the accuracy of more than optical observations, but also greatly improved operating speed, and can provide direct point of geocentric coordinates of the ground.

现代实用天文学是18世纪发展起来的，先后从理论和实践上解决了中星仪测时、太尔各特测纬以及多星等高法同时测定经度和纬度的方法，出现了经纬仪、等高仪、中星仪、天顶仪、照相天顶筒、六分仪等实用天文学仪器，最常用的是光学全能经纬仪。20世纪60年代以后实用天文学领域出现了崭新的技术，如人造卫星多普勒观测和人卫激光测距，不但精度超过光学观测，而且作业速度大大提高，并能直接提供地面点的地心坐标。

Battleship secondary batteries and light cruiser main batteries by this time were also director controlled with telephone transmission of range and deflection data sent from plot to the sight setter on the guns.

在那个时代，战斗舰的副炮与轻巡洋舰的主炮也已经由射控站指挥并透过电话来传递距离参数，至於偏转角度则由炮塔上的光学测距仪提供。

然而EDM作为一种光学和电子器件组成的测量仪器，由于生产、运输、使用过程中的误差、震动和环境因素的影响以及电子器件本身的老化等，导致仪器的部分性能指标发生变化，最终是使测距仪测量观测值的精度受到影响。

Laser rangefinder consists of laser emission source, receiving system and optical antenna.

半导体激光测距仪主要由激光发射光源、接收系统和光学天线组成。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
