Because Dione is relatively small, an impact causing a 35 kilometer crater could have spun the satellite.

由于土卫四比较小，在受到比较大的撞击（撞击坑大于35千米）时它会被转动。

Since there are many craters larger than 35 kilometers, Dione could have been repeatedly spun during its early heavy bombardment.

由于土卫四表面有许多大于35千米的撞击坑，因此它在早期撞击率比较高时可能不断被转动。

In this paper, the modeling theory of multi-rigid-body dynamics was thoroughly investigated in order to make up the shortcoming in the above modeling method. The major research achievements are as follows:①Based on the matrix of direction cosine between the body-fixed base and the reference base, and Poisson equation of a rigid body rotating, the coordinate transformation method for the modeling of treelike multi-rigid-body dynamics is derived. The method is very routinization and easy to use the computer to carry on the symbol derivation.
