天赤道

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。

Astronomy the equinoctial point that lies in the constellation of ''.

黄道与天赤道相交的一点，自此太阳向南运动。

Sadalmelik is only one of two stars with ancient proper names to lie within a degree of the celestial equator (the circle in the sky that runs from exactly east to west and lies directly above the equator of the Earth), the other Mintaka in Orion (Orion's right-hand belt star), although Porrima Virgo comes close.

Sadalmelik这个名字是自古沿用至今的，而且这样的星名也只有两个，它们都与天赤道成一定角度--天赤道就是将地球的赤道面无限延伸后和天球相交的大圆圈，其方向为自东向西。另一个是猎户座δ星Mintaka--位于猎户右手带子上--尽管处女座γ星Porrima靠近她，却没有这种荣耀。

Today is another Equinox + 1 day, with the Sun crossing the celestial equator yesterday at about 17:32 Universal Time.

今天是另一个春分+1天，昨天世界时17：32太阳运行经过天赤道。

Today, the Sun crosses the celestial equator heading north at 11:44UT.

今天，太阳在世界时11：44过天赤道向北（这话拗口，说这个时候太阳直射地球的赤道线就好理解多了——译注）。

Either of the two times during a year when the sun crosses the celestial equator and when the length of day and night are approximately equal; the vernal equinox or the autumnal equinox.

二分时刻一天中太阳通过天赤道的两个时刻中的任一时刻，此时昼夜长短几乎相等；春分或秋分

Actually a composite of 300 consecutive 1-minute exposures, the image nicely shows stars near the celestial equator tracing nearly straight lines in projection, while stars north and south of the equator, respectively, appear to circle the north and south celestial poles .

上图实际上是一300幅连续1分钟抓拍的合成图像，显示出了接近天赤道附近的恒星轨迹投影近乎直线，而天赤道南北的恒星轨迹，分别显示为环向南部和北部天极的弧形。

This is a testament to its timeless design. Then followed by the introduction of famous Sky Patrol portable mount in 1981, this mount was a favorite for eclipse chasers. It features a polar alignment telescope in the R.A.

这是一款经得起时间检验的经典赤道仪。1981年又开发了便携式巡天赤道仪，极大地满足了爱好者们观看日月食，该产品的特色是在R.A。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.
