Since the basic theoretical framework of generalized Hamilton system is not
perfect and complete, there are often some practical problems that can not be
expressed by generalized Hamilton system. The generalized gradient operator is
defined by the structure function on manifold to improve the basic theoretical
framework of the whole generalized Hamilton system. The generalized structure
Poisson bracket is defined as well on manifolds. The geometric bracket is also
given, and the covariant extension form of the generalized Hamilton system
directly related to the structure function, the generalized covariance, is
further obtained--generalized covariant Hamilton system, It includes thorough
generalized Hamiltonian system and S-dynamic system.Comment: 15 page
