- A unit of measure of longitude or right ascension, equal to15=or!/ 24of a great circle. 经度15°经度或赤经单位，相当于15°或圆周的二十四分之一
- Any reference star that if found to show larger residual in either Right Ascension or Declination will be rejected from the astrometric solution. 任何一个参考星的赤经或赤纬偏差超过这个值将被拒绝进行天文测量处理。
- Each search area is about 10 degrees in declination and one hour of right ascension. 每个搜索区域有大约包括赤纬10度，赤经一小时。
- A unit of measure of longitude or right ascension, equal to15= or! /24 of a great circle. 经度15°经度或赤经单位，相当于15°或圆周的二十四分之一
- The location is also noted in the lower right corner in celestial coordinates (Right Ascension and Declination). 这个位置也以天球坐标形式显示在右下角（赤经和赤纬）。
- The method needs not to compute the right ascension,so it is very simple and economical. 由于不需通过计算去求赤经,因而这是一个简单而又经济的方法。
- The third section first idea circle of right ascension is not very ideal, but last already infinite close perfect. 第三节的第一个计时圈不是很理想，但最后一圈已经无限接近完美的一圈。”
- If checked, a grid of lines will be drawn every 2 hours in Right Ascension and every 20 degrees in Declination. 选取此选项的话，会绘出坐标格。赤经每两小时画一条线，赤纬则是每20度画一条线。
- A large reflect meridian circle is an instrument for the absolute determination of the declination and right ascension of a star. 大型反射子午环是用来绝对测定恒星赤经和赤纬的仪器。
- Till 1995, the deviations of the origin of right ascension and the celestial pole from their originally expected positions are no less than 0. 4mas. 至1995年，IERS天球参考架的赤经零点和天极与各自预期位置的偏差不于0.;4mas。
- Phase modulated resolvers can be used to model the relation between the sidereal time, right ascension and the hour angle. 工作在调相状态下的旋转变压器可以用其相位模拟恒星时与赤经、时角的关系。
- From our perspective they appear in the constellation of Taurus, with approximate celestial coordinates of3 hours45 minutes right ascension and+24 degrees declination. 通过我们的观测，它们好象在金牛星座里，对应天球坐标为赤经3小时45分及+4度偏差。
- From our perspective they appear in the constellation of Taurus, with approximate celestial coordinates of 3 hours 45 minutes right ascension and +24 degrees declination. 通过我们的观测，它们好象在金牛星座里，对应天球坐标为赤经3小时45分及+24度偏差。
- The right to dissent is part of our political system. 有持异议的权利是我们政治体制的组成部分。
- There are 4 Hipparcos stars among the 11 stars. The mean internal errors of proper motions of them in right ascension and declination are 0. 024ms/a and 0. 21mas/a, respectively. 其中有4颗是依巴谷星，它们的赤经和赤纬自行精度的平均值分别为0.;024ms/a和0
- When all people run the first idea circle of right ascension, Hamilton rushes to the first place, but Gerlach immediately after second idea circle of right ascension leads once more. 当所有人跑完第一个计时圈时，汉密尔顿冲到首位，但格洛克马上在第二个计时圈后再次领跑。
- Her clothes are always right up to the minute. 她的衣服总是式样最新的。
