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 .

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。

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 % .

各缝核双标细胞占整个延髓缝核HRP标记细胞总数的百分比分别为：大缝核7.5%，隐缝核2.9%，苍白缝核1.4%。
