第76章 对火星轨道变化问题的最后解释（2/2）

first， we briefly look at the general character of the long-terary orbits. our interest here focuses particrly on the inner four terrestrial pls for which the orbital tis. as we can see clearly fros differ little between the initial and final part of each nus lie ry orbital ary orbits (fros (taken fros in the initial and final part of the integration n+1 is shown in fig. 4. as expected， the character of the variation of ry orbital ele is the shortest of all the pls， which leads to a s; the inner ary systes seeary ary dynaary orbital ary orbital s， although typical frequencies differ pl by pl and eleary orbital energy and angr ary orbital angr ary orbital energy e per unit ary systes and all nine pls are shown for integration n+2. the upper three panels show the long-periodic variation of total energy (denoted ase- e0)， total angr s calcted fros. the fluctuation shown in the lower panels is virtually entirely a result of the s.

还有其他论文，不过也都是英文的，相关课题的中文文献很少，那些论文下载一篇要九美元（《nature》真是暴利），作者君写这篇文章的时候已经回家，不在检测中心，所以没有数据库的使用权，下不起，就不贴上来了。
