All the above physical parameters conform the approximate ellipse law.

各种物性参数均遵循近似椭圆规律变化。

And then his third law was that if you take the orbital period of an ellipse, that is proportional to the third power of the mean distance to the Sun.

第三定律是，椭圆轨道的周期，和距太阳的平均，距离的，立方成比例。

To join ellipse yield function, hardening parameter with plastic work, associated flow law and damage theory, the elastoplastic damage constitutive model of loess were derived.

结合以塑性功为硬化参数的椭圆形屈服面，根据相关联流动法则及损伤理论推导出了黄土弹塑性损伤本构模型。
