英文摘要：

Firstly, a fractional gene and a fractional increment are put forward and the definitions and properties of fractional derivative and integral with fractional gene are given. Secondly, the exchanging relationship between the isochronous variation and fractional derivative with the fractional gene is proved. Thirdly, the fractional Hamilton principles and fractional differential equations with fractional gene for holonomic dynamical systems are presented. Further, the fractional circulatory integrals of the systems are obtained and the fractional Routh＇s equations with fractional gene are derived. Finally, two examples are given. This research indicates that the fractional differential equations can become the conventional differential equations with fractional gene, and the general methods for solving the conventional differential equations are also applicable for solving the fractional differential equations .
