according to the study of orbital eccentricity of binary stars jeans proves that the age of our galaxy is of the order of 10~(13) years(long time scale), but ambarzumian rejects his theory.
taking the design of venus gravity-assist trajectories as an example, the relation between orbital eccentricity and orbital inclination was analyzed.

this paper introduces some new developments concerning orbital eccentricity in stratigraphic and paleoclimatic studies.
介绍了偏心率周期在地层和古气候研究方面的新发展。
the orbital inclination, orbital altitude, elevation of gps antenna and orbital eccentricity were researched as the influential factors to doppler range.
研究轨道倾角、轨道高度、gps天线仰角和轨道偏心率等因素对多普勒频率搜索范围的影响。
in this paper, we discuss the orbital eccentricity distribution for 143 early-type and 125 late-type binary systems.
