查询词典 reflecting telescope

Most astronomical reflecting telescope glass mirror components are made of borosilicate glass because of its low coefficient of expansion with heat.

大多数天文反射望远镜玻璃镜面组成部分是由硼硅玻璃，因为它低膨胀系数与热。

With the astrophysics of the the rapid development, many of the Observatory in the construction of a large reflecting telescope, and select the best of all the host sites.

随着天体物理学的迅速发展，很多天文台都在建造大型的反射望远镜，并选择条件最佳的台址。

Reflector telescope relative a larger diameter can be done, the main focus of the relative telescope diameter is about 15-125, even greater, Wang DC, inter Newton Telescope, the tube is longer than the system is much shorter focal length, coupled with the main mirror is only one apparent need for processing, which greatly reduces cost and manufacturing difficulties, there is currently greater than 134 meters diameter optical telescopes are all reflecting telescope.

反射望远镜的相对口径可以做得较大，主焦点式反射望远镜的相对口径约为15—125，甚至更大，而且除牛顿望DC远镜外，镜筒的长度比系统的焦距要短得多，加上主镜只有一个表面需要加工，这就大大降低了造价和制造的困难，因此目前口径大于134米的光学望远镜全部是反射望远镜。

Of telescope, the reflecting telescope.

Sir William Herschel discovered the planet Uranus in 1781 with a hand-made reflecting telescope. Eight years later supported by finding from King George Ⅲ Herschel completed construction on his 40-foot telescope in Slough England.

威廉·赫歇尔先生在1781年发现天王星，用的是手工制作的反射望远镜。8年后，因为从国王乔治三世那儿寻求到了支持，赫歇尔在英国斯洛福完成了他的40英尺望远镜建造。

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。
