The coordinate transformation between CRS and TRS based on equinox and NRO is also shown .

基于春分点和NRO的坐标转换模型以及其中的有关参数的确定。

Guinot has proposed a " non-rotating origin " ( NRO ) to serve as such a reference point .

Guinot建议以非旋转原点作为这样的一个参考点。

Both NASA and the NRO are tight-lipped about the specifics .

但NASA和NRO对细节一直守口如瓶。

The NRO looks after the distribution of these addresses to the local Regional Internet Registries ( RIRs ), who in turn then distribute those IP addresses to ISPs that connect you to the Internet .

NRO负责将这些地址分配给地区的RIR，RIR转而将这些IP地址分配给互联网服务提供商（ISP），ISP再确保让你连接到互联网上。

That the NRO felt able to give them away suggests that its spies have even better toys to play with , of the sort that astronomers would kill to get their hands on . Could this be the start of a beautiful friendship ?

NRO觉得把它们送走之后自己的间谍们就有更好的玩意来耍了，要是这样的话，估计天文学家们打死都不会接受的——这会是NRO和NASA一段美好友情的开始吗？

The adoption of the International Celestial Reference System and the changes of observational strategy call for the use of departure point on the moving equator independently from Earth 's orbital motion . A Nonrotating Origin ( NRO ), proposed by Guinot , is selected .

国际天球参考系的使用、观测精度的提高和方法的改善要求采用与地球轨道运动无关的运动赤道上的起算点，Guinot提出的非旋转原点可作为这样一种选择。

IAU will adopt the Celestial Intermediate Pole ( CIP ) as the celestial reference pole from 1 January 2003 . The use of NRO in the Celestial Reference System ( CRS ) is designated as the Celestial Ephemeris Origin ( CEO ) .

IAU决定从2003年起采用天球中间极作为天球参考极。

Using a higher-resolution NRO mirror would boost the capabilities of WFIRST , says Alan Dressler , a researcher at the Carnegie Institution for Science . It could also cut the project 's cost ( its present price tag is about $ 1.6 billion ) and shorten its development time .

卡内基科学研究所的研究员AlanDressler说，运用NRO卫星的高分辨率望远镜可以提升WFIRST的能力，也可以降低该项目的花费（红外线望远镜的当前市价为16亿美元）并缩短研制时间。
