查询词典 Telescope

Astrometry with new technologies created and is dedicated to the Space Telescope astrometric space orbit around the Earth observation and research on the scientific .1989 8 8, the European Space Agency launch astrometric Satellite Iba Valley satellite, which contains a 29 cm diameter reflecting telescope, four ground stations for data reception and analysis with the aim of space-based observations compiled by 120,000 to contain space for satellite measurement of star form, the location accuracy of ± 0002, parallax measurement accuracy ± 0002, on their own a year 0002, CDCDCD preliminary estimate of the above three data are now actual for the 0004,0003 and 0005; CDCDCD190 year in April the U.S. launch of the Hubble Space Telescope, containing 24 m diameter Wang C far mirror can work 15-20 years, 17-18 so you can measure the parallax of stars, are hundreds of thousands of stars of the measurement results.

伴随天体测量新技术而产生，是专门用于天体测量的空间望远镜在围绕地球的空间轨道上进行观测研究的科学。1989年8月8日，欧洲空间局发射天体测量卫星伊巴谷号卫星，它载有口径29厘米反射望远镜，4个地面观测站进行资料接收与分析，目的是要通过空间观测编出含星12万颗的空间测量星表，位置精度为±0002，测量视差的精度为±0002，自行为每年0002，CDCDCD现在初步估计上述三个数据实际为0004、0003和0005；CDCDCD190年4月美国发射哈勃空间望远镜，载有口径24米的望C远镜，可工作15—20年，可以测量出17—18等星的视差，得到几十万颗星的测量结果。

Meanwhile, astronomers in California were building the largest telescope in the history of the world - a new telescope on top of Mount Wilson, near Pasadena, with a mirror 100 inches (2.5 meters) across. In 1923, Edwin Hubble used this new telescope to prove that some of the nebulae, including the Sombrero, are actually other galaxies similar to our own Milky Way.

期间，天文学家在加利福尼亚建造了当时世界上最大的望远镜，该望远镜在 Pasadena 附近的威尔逊山顶，拥有2.5米的镜面。1923年， Edwin Hubble 用这个新的望远镜证明部分星云包括 Sombrero 实际上是和我们的银河系一样是星系。

The world's most powerful telescope for observing the universe in high-energy gamma-ray light, the observatory was originally called the Gamma-ray Large Area Telescope, but was rechristened after Italian scientist Enrico Fermi once the telescope was up and running in space.

这台世界上最强大的望远镜是通过高能伽马射线观察宇宙，最初这个天文台被称作&伽马射线广域空间望远镜&(Gamma-ray Large Area Space Telescope)，但是当这台望远镜建成后开始正常运行时，人们又根据意大利科学家恩里科·费米的名字给它重新命名。

Accordingly, as the major targets weighing the quality of the telescope,its luminous energy concentration degree directly influence the quality of the image of the celestial body. So many kinds of technique about the optical quality testing of telescope have came forth. Hartmann screen test is one of the most classical among them and it has become one of the main testing method on several large-scale telescopes in the world because of some strongpoints suchas briefness, visuality and easy handlment.The image through the350mm telescope of the Yunnan observatory has aberration in general, subsequently,the relative position of the primary mirrior has err when blooming and reinstalling .

因此，天文望远镜光能集中度作为衡量天文望远镜质量的重要指标，直接影响到所成天体像的质量好坏，所以就出现了多种天文望远镜光学质量检测方法，其中最经典的是哈特曼光栏法，它因简单、直观、操作方便等优点而成为世界上多台大型天文望远镜的重要质量检测方法之一。

Chapter 5 gave the results of optical positions of 45 radio sources using 1m telescope of Yunnan Astronomical Observatory, Schmidt telescope and 60cm telescope of Beijing Observatory, the comparison with the results of other authors is also given.

第五章给出我们利用云南天文台l米望远镜、北京天文台施密特望远镜以及60厘米望远镜配备的CCD观测45颗河外射电源的结果，给出它们在不同参考星表中得到的光学位置，并与其他作者的结果进行了比较。

And by means of photography, new wonders of that glory have been revealed. A photographic plate fixed below the telescope will reveal millions of stars, which could never have been seen by the eye through the best telescope.

并且又因天文摄影的方法发现了许多新奇的领域，一块照像的感光片，放在天文望远镜底下，可以照出千万个用最好的望远镜所不能看见的众星。

As noted in the article "How to Choose a Telescope," telescope mounts come in two basic types: equatorial and altazimuth.

在《如何选择望远镜》一文中提到，望远镜支架有两种基本类型：赤道式和地平式。
