First, a climate conducive to life on Earth depends upon the extraordinarily narrow orbital parameters that define a continuously habitable zone where water can exist in a liquid state.
首先，地球上适宜生命存在的气候取决于极其狭窄的轨道参数，这些参数定义了一个持续可居住的地带，在那里水可以以液态存在。
Therefore, the change of Earth orbital parameters is just one of factors, which could lead to the paleoclimate variation.
因此，地球轨道参数变化影响气候长期变化只是其中一种因素。
Accordingly, the influence of the earth's orbital parameters on the radiation term in the climatic change is also discussed.
据此讨论了气候变化中地球轨道参数对辐射项的影响。
Up to now, the Earth's orbital parameters remain the only periodicities in geology subject to precise calculations and, therefore, may provide new scales for geochronology.
迄今为止，地球轨道参数的变化是地质尺度上惟一可以精确定量计算的周期现象，可以用作地质计时的标尺。
When the planetary migration occurs under the tidally interaction of a planet and a disk of gas or a planetesimal, the orbital parameters, especially, semi-major axis, of this planet will be altered.
行星迁移发生在行星与气体或星子的星盘之间进行潮汐相互作用时，这造成行星轨道参数，特别是半主轴的变更。
