Balanced cross-section is a base rule in geology . The key of it is: if the area or length of layer is in the same size after it's deformation ,the cross-section is balanced , or ,if not, the cross-section is unbalanced. Any interpret about it is not right.In this paper,we would make a balanced cross-section by the computer,after we stduied a serials of model about balanced cross-section .And we will give some examples of typical cross-section.Discretization is a new method in this paper. Any deformation in distortion can be described by a lots of particle .We can describe whole process of deformation by describing every particle's motion. |
