The influence of two definitions for arbitrary particles on the shape-affecter

The equivalent area method and inscribed circle method are put forward based on the ellipse method of arbitrary particles for expressing their sizes,the expressions of their shape-affecter and solution of them are studied upon above methods.We think the inscribed circle method as a good expressing for arbitrary particles' size after compared them with each other in their dynamical character.Then,a good gist is established to measure the function of particles' character in theory through the shape-affecter drafting.
