中文摘要：

Hamilton-Jacobi方法通常被认为是求解完整保守Hamilton系统正则方程的重要手段，但通过现代微分几何理论发现，这种方法的适用范围不仅仅局限于完整保守的Hamilton系统．根据Hamilton—Jacobi理论，证明了经典Hamilton—Jacobi方法可以被推广至一类特殊的非保守Hamilton系统，即如果非保守Hamilton系统受到非保守力，则该系统的Hamilton正则方程也可以用Hamilton—Jacobi方法求解；对于这类非保守Hamilton系统，只要能够找到其对应的Hamilton—Jacobi方程的一个完全解，就可以得到系统正则方程的全部第一积分．经典的Hamilton—Jacobi方法则是上述方法的一个特例．

英文摘要：

The Hamilton-Jacobi equation is an important nonlinear partial differential equation. In particular, the classical Hamilton-Jacobi method is generally considered to be an important means to solve the holonomic conservative dynamics problems in classical dynamics. According to the classical Hamilton-Jacobi theory, the classical Hamilton-Jacobi equation corresponds to the canonical Hamilton equations of the holonomic conservative dynamics system. If the complete solution of the classical Hamilton-Jacobi equation can be found, the solution of the canonical Hamilton equations can be found by the algebraic method. From the point of geometry view, the essential of the Hamilton-Jacobi method is that the Hamilton-Jacobi equation promotes the vector field on the cotangent bundle T＊M to a constraint submanifold of the manifold T＊M × R, and if the integral curve of the promoted vector field can be found, the projection of the integral curve in the cotangent bundle T＊M is the solution of the Hamilton equations. According to the geometric theory of the first order partial differential equations, the Hamilton-Jacobi method may be regarded as the study of the characteristic curves which generate the integral manifolds of the Hamilton 2-form w. This means that there is a duality relationship between the Hamilton-Jacobi equation and the canonical Hamilton equations. So if an action field, defined on U ×I （U is an open set of the configuration manifold M, I R）, is a solution of the Hamilton-Jacobi equation, then there will exist a differentiable map φ from M × R to T＊M× R which defines an integral submanifold for the Hamilton 2-form ω. Conversely, if φ＊ω = 0 and H1（u × I）= 0 （HI（U × I） is the first de Rham group of U × I）, there will exist an action field S satisfying the Hamilton-Jacobi equation. Obviously, the above mentioned geometric theory can not only be applicable to the classical Hamilton-Jacobi equation, but also to the general Hamilton-Jacobi equation, in which some first order part
