讨论了一种特殊的图形—格子 ,并给出了格子角线数定理和格子角线数的性质。

In this paper, we have discussed a special geomatric figure—the rectangle divided into some squares, and raise a theorem and six characters on the number of special route in the rectangle divided some squares. All of those are very beneficial to inspaire the thought of induction and to develope intelligence.
