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。
“ But it made us think ,” Donald Kerr , NRO director , said at the time .
美国国家侦察局局长科尔当时就表示：“但这令我们深思。
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 .
The ratio of double labeled neurons of individual nucleus in total HRP labeled neurons of raphe nuclei of medulla oblongata was as fol lows : NRM 7.5 % , NRO 2.9 % , NRP 1.4 % .
A series of new concepts and methods about coordinate transform presented by IAU are parsed in depth , methods of coordinate transformation between GCRS and ITRS based on vernal equinox and NRO are derived in detail , relations among various transform parameters and their calculated methods are studied . 3 .
