天赤道

行星在天赤道（celestialequator）上的升落使得赤纬成为了业力占星学中需要考虑的第三个因素。

As the planets rise and fall on the celestial equator , Declination becomes another factor of planetary karma that we need to consider .

垂直于南北极轴把天球平分成南北两半的大圆就是天赤道。

The east-west axis , vertical to the north-south one , was the heavenly equator .

使晷面平行于天赤道面。

The sundial surface is therefore parallel to the equatorial plane .

秋分：指黄道与天赤道相交的一点，自此太阳向南运动。

Autumnal equinox : the point at which the ecliptic intersects the celestial equator , the sun having a southerly motion .

太阳离天赤道的距离最远时的两次中的任何一次。

Either of the two times of the year when the sun is at its greatest distance from the celestial equator .

从观测者所在的子午线到给定天体的子午线沿着天赤道的角距离。

The angular distance along the celestial equator from the observer 's meridian to the hour circle of a given celestial body .

天球纬度是从天赤道向南或向北以度数来表示，叫做天体的偏角δ。

The celestial equivalent is measured in degrees north or south from the celestial equator and is called the declination of the body .

太阳每年通过天赤道的两个时刻中的任何一个时刻，在此时各地的昼夜时间是等长的。

Either of two times of the year when the sun crosses the plane of the earth 's equator and day and night are of equal length .

从秋分到春分期间，太阳在天赤道的南侧运行，因此，晷针的影子投向晷面的下方。

Likewise ， since the sun moves in the southern side of the equator from the autumn equinox to the vernal e-quinox , the shadow is cast on the lower part .

采用复经验正交函数（CEOF）方法分析了准40天振荡沿赤道和某些大圆路径传播的规律。

The regular patterns of the propagation of quasi-40-day oscillations along the equator and some great circle routes are analysed and revealed by a complex empirical orthogonal function ( CEOF ) method .

对流的30&50天振荡在赤道上具有自西向东的纬向传播，厄尔尼诺年传播可以通过日界线到达东太平洋地区，而正常年传播一般在日界线以西的地区出现截陷。

The 30 & 50 day oscillation of the convection travels eastward along the equator , crossing the dateline into the eastern Pacific in the El Nino year and trapped to the west in normal years in general .
