数字立方映射H_n的全局分叉结构（奇数部分）

The Global Bifurcation Structure of the Digital Cubic Mapping(the Part of Odd)

本文讨论了数字立方映射Ｈｎ：ｘ→［ｘ３］．的个位是奇数的数，随ｎ增大时的全局结构及分又结构，得到了个位是３．７、５的数，随ｎ增大时Ｈｎ的全局分叉结构，并得到了个位是１、９的数的主要结果．这些结果比个位是偶数的数的相应结果要复杂的多．

When unit's place is odd number, the global structure and bifurcation structure of the mapping Hn: x→ [x3] .is studied. As n is increasing, the global bifurcation structure of that unit's peace-3, 7, 5 is obtained, and the important conelusion of the unit's place 1. 9 is obtained, too. These results are more complicated than that of the even number of the unit's place.
