赤经

Astronomy the angular distance of a celestial point measured westward along the celestial equator from the zenith crossing; the right ascension for an observer at a particular location and time of day .

从天顶交叉口向西顺着天赤道测量的一个角距离；对在一个特定的地点和特定的时间观测者来说是赤经。

Clamp and rotate the polar axis until the Polaris circle on the reticle is directly below.

松开赤经制动钮并转动极轴直到划分板上的北极星圈置于正下方。

A unit of measure of longitude or right ascension, equal to 15= or !

经度15°：经度或赤经单位，相当于15°或圆周的二十四分之一

At last in the paper, We compute solar declination and solar right ascension based on this algorithms and compare the result with the given data.

文中还根据此算法计算了太阳赤经和太阳赤纬，并对结果进行了比较，最后给出了在太阳能发电中的应用实例。

Biases in right ascension and declination were 0.32 and -0.74 arc-s.

偏差在赤经及赤纬为0.32和-0.74弧。

In this paper, the impacts of 4 types of LEO orbit parameters —argument of latitude, right ascension of ascending node, orbit height and inclination—on the distribution and number.

分析了对于单颗LEO卫星，掩星事件的分布和数量随着LEO 轨道参数包括轨道升交角距、升交点赤经、轨道高度和倾角而变化的规律，并得出了相应结论。

This paper presents the formula of the initial values of theorbital parameters— celestial longitudeφ_0 of the sun, right ascension ofascending nodeΩ_0 and argument of perigeeω_0, used for calculating orbitalheat flux received by satellite.

文章给出了卫星热分析空间外热流计算中所需要的轨道参数太阳黄经、交点赤经和近地点幅角的初值φ0、_、_的计算公式。

Latin:"Balance", in astronomy, zodiacal constellation lying between Scorpius and Virgo, at about 15 hours 30 minutes right ascension (the coordinate on the celestial sphere analogous to longitude on the Earth) and 15° south declination (angular distance south of the celestial equator).

从天文学上说，天秤座，黄道星座，位于天蝎座和处女座之间，约位于赤经15时30分（类似于地球经度的一种天球坐标），南赤纬15度。

Please read this document carefully and report the observations in the correct format noting that the UTC time of observation should be reported to 0.00001 day, the R.A.

请仔细阅读该文件并按照正确的格式上报（注意，时间必须精确到0.00001天，赤经必须精确到0s.01，赤纬必须精确到0.1，星等必须精确到0.1等）。

Plates of globular cluster M3, taken with the 40cm refractor at Sheshan station of Shanghai Astronomical Observatory, are used by this work. The difference of epoch of these plates is up to 81years. The positions and absolute proper motions of 24 stars in ACT catalogue, which links with the Hipparcos Catalogue based on the International Celestial Reference System, are used as the reference frame. Using the central overlapping principle, the absolute proper motions of 534 stars in the region of about 100'×100' around the cluster are determined. After the membership determination of the stars which based on the data of proper motions, average absolute proper motion components for the cluster of -0.3±0.3 mas/yr in R.A.

本文使用上海天文台佘山40厘米折射望远镜拍摄的14张最长时间跨度为81年的球状星团M3底片的PDS扫描结果，使用与 Hipparcos星表相联系的基于国际大球惯性参考系的ACT星表中的 24颗恒星的位置和绝对自行为参考架，用中心重叠法进行天体测量归算，得到了这个星团中心附近100'×100'天区内534颗恒星的位置和绝对自行，并利用这些自行对成员概率进行了估算，得到这个星团的赤经方向绝对自行为- 0.3±0.3mas/yr，赤纬方向绝对自行为-3.1±0.3mas／yr。
