sidereal

The sidereal year is not used to construct a calendar .

恒星年不用于编制年历。

A sidereal day is about 4 minutes shorter than a solar day .

一个恒星日比一个太阳日大约短4分钟。

Acceleration of sidereal on mean solar time

平太阳时换算恒星时的增量

A sidereal day is shorter than a mean solar day by 3 minutes and 56 seconds .

恒星日比平均太阳日短三分五十六秒。

It gave mean solar time , mean sidereal time , equation of time , and could chart the phases of the moon .

表盘上不仅能显示平太阳时，还能显示平恒星时、时差，记录月相。

Phase modulated resolvers can be used to model the relation between the sidereal time , right ascension and the hour angle .

工作在调相状态下的旋转变压器可以用其相位模拟恒星时与赤经、时角的关系。

For the declination control system there is no need of modulating sidereal time into the signal which excites the resolver stator windings .

对赤纬控制系统，不需把恒星时调制到旋转变压器激磁信号中去。

Its period is about half sidereal month , and amplitudes are about 3 km and 3 ms ~ ( - 1 ) .

它的周期约半个恒星月，振幅约3km和3ms~（-1）。

GPS Synchronizing Sidereal Clock

GPS同步恒星钟

Setting Right Ascension-After polar alignment , the observer uses a calculator or a known star to synchronize the right ascension circle with Sidereal Time .

设定赤经&在校准好极点以后，观测者必须利用计算机或已经同步好恒星时的装置设置好赤经圈。

For the variation of short period of astronomical factors , whether for local time or local sidereal time and lunar phase there is the phenomenon of occurrence of concentrating a interval time for the earthquakes .

对于天文因素的短周期变化，无论是对于地方时，地方恒星时与月相，都有集中发生在某一段时间的现象；

The sidereal diurnal variation of cosmic ray ties up with the most basic and important problem in cosmic ray physics such as the origin , propagation and the acceleration mechanisms of cosmic ray .

宇宙线的恒星日变化紧密联系于宇宙线的起源、其传播途径的性质，以及宇宙线的加速机制等宇宙线物理中最基本的重大问题。
