英漢例句
- American mathematician and astronomer who published an almanac (792-802) containing ephemerides that he had calculated.
班尼克，本杰明：(73-80')美國數(shù)學(xué)家和天文學(xué)家，他出版了一本歷書（792-802年），其中包含他計(jì)算出的星歷表 - GPS satellite precise ephemerides provided by IGS describe there dimension position of GPS satellites in ITRF.
IGS提供的精密星歷描述了GPS衛(wèi)星在地固系中的三維位置。 - American mathematician and astronomer who published an almanac (1792-1802) containing ephemerides that he had calculated.
班尼克，本杰明：(1731-1806)美國數(shù)學(xué)家和天文學(xué)家，他出版了一本歷書（1792-1802年），其中包含他計(jì)算出的星歷表 - From those optical data and the ephemerides of the sun and the earth, the iterative least square (ILS) method was used to estimate the epoch state of the lunar satellite's orbit.
對該自主導(dǎo)航算法進(jìn)行了數(shù)學(xué)仿真,分析比較了敏感器精度、部分軌道參數(shù)等因素對定位精度的影響,總結(jié)了其變化規(guī)律。 - The formulae of correction for the other observations are also given.With these corrections,We can use the simplest formulae to calculate the satellite ephemerides in impro...
經(jīng)過這些改正后,在軌道改進(jìn)時(shí),星歷表計(jì)算就可用最簡單的時(shí)間對應(yīng)的公式計(jì)算,不必進(jìn)行迭代,也無需加任何附加項(xiàng)。
