查询词典 celestial equator

A pulsar is a celestial object that emits light in short burst a pulsar in the crab nebula flashes at a rate of 30 times/s,suppose the light pulses are caused by the rotation of a spherical object that emits light from a pair of diametrically opposed "flashlights" on its equator.

脉冲星是一种以短爆发形式辐射光的天体。假设球型天体赤道面上有一对"发光塔"，并且这对发光塔的联线构成赤道面的直径，进一步假设光脉冲产生于球形天体的转动，那么巨蟹座星云中的一个脉冲星的闪光频率是每秒30次。

The adoption of the International Celestial Reference System and the changes of observational strategy call for the use of departure point on the moving equator independently from Earth's orbital motion. A Nonrotating Origin, proposed by Guinot, is selected.

国际天球参考系的使用、观测精度的提高和方法的改善要求采用与地球轨道运动无关的运动赤道上的起算点， Guinot提出的非旋转原点可作为这样一种选择。

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。

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。

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

行星在天赤道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。

Equinox means equal night and with the Sun on the celestial equator, Earth dwellers will experience nearly 12 hours of daylight and 12 hours of darkness.

春分意味着在夜晚和太阳在天球赤道上的时间相等，地球上的居民将经历12小时的白天与黑夜。

A theoretical sun that moves along the celestial equator at a constant speed and completes its annual course in the same amount of time the ''.
