| Abstract: | By studying bound combination, the bound combination with fixed elements and the cirle bound combination with fixed elements are both defined. By use of generating function and counting techniques like principle of addition and principie of multiplication, a series of counting formulas for the bound combination with fixed elements and the cirle bound combination with fixed elements is listed. |
