| Abstract: | Two mathematic models are built.One is the model of touching balls.The other is the model of moving bricks.Using two mathematic models,a new demonstrating method is given out for the repeated combination formula.Its features are direct,understandable and imaginable.It is more simple than the one in the document1]. |

| Keywords: | repeated combination mathematic model differential element |
