That's when-on the imaginary dome 圆屋顶 of sky surrounding Earth-The two planets share the same right ascension赤经, which is like celestial天上的 longitude.

这一天这两颗行星在虚构的包围地球的天穹上享有同样的赤经，赤经就好比天上的经线。

The analysed results show that among the 106 earthquakes of above magnitude 7.0 in 20th century,there are 71% occurred in the period when angle between Moon′s path and the celestial equator turns small and there are over 62% happened when the lunar longitude of ascending node lies from 350° to 210°.

分析结果表明，本世纪106次7.0级以上大地震71%发生于月亮轨道与赤道交角变小阶段，62%以上发生于月亮升交点黄经位于350°～210°期间。

The position of two celestial bodies when their longitude differs by 180=, especially a configuration in which the earth lies on a straight line between the sun and a superior planet or the moon.

两星体以180°相对的位置：两个星体在天空中处于180°的直线位置，尤指当地球和外行星或月球成一直线的位置

The position of two celestial bodies when their longitude differs by180=, especially a configuration in which the earth lies on a straight line between the sun and a superior planet or the moon.

两星体以180°相对的位置两个星体在天空中处于180°的直线位置，尤指当地球和外行星或月球成一直线的位置除已知星体之外，我们不了解的其他天体

Based on this, the characteristics of related celestial body positions at the occurrence time of the triggered earthquakes are studied. The distribution patterns, which have tidal_triggering physical basis, of lunar_solar ecliptic longitude differences and declinations and zenith distances are obtained.

在此基础上，对受到潮汐应力触发的地震发震时的天体位置特征进行了研究，得到了具有潮汐应力触发物理基础的地震时的月日黄经差、月日赤纬和月日天顶距的分布图像。

In this paper, the basic mathematical model was derived by means of two methods, the first is the twostar positioning algorithm in celestial navigation theory and the second is based on the gyro dynamics theory. The results from these two methods are identical and therefore are correct. The latitude is equal to the elevation-angle of the polar gyro. The course is the ideal output from the sensor fitted to the outer gimbal. The longitude is a function of the equator gyro's azimuth and elevation angles.

本论文用天文导航中的双星定位法和经典的陀螺力学原理两种方法建立了ESGM的基本数学模型，并且得到一致的结果，说明所建模型是正确的，即载体的纬度等于极轴陀螺主轴相对水平面的高度角，载体的航向等于极轴陀螺外环轴上角度传感器的理想输出，载体的经度是赤道陀螺的方位角和高度角的函数。

The circle of space surrounding the earth and measuring 360 degrees of celestial longitude is known as the zodiac.

围拢地球和测量360度黄经的空间圈子叫作黄道带。

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。
