Generalized canonical transformations of a kind of generalized Birkhoff systems
一类广义Birkhoff系统的广义正则变换

The generalized canonical transformations of a kind of generalized Birkhoff systems are studied in this paper. The differential equations of motion of the generalized Birkhoff systems are estallished. The condition under which the transformations of the system are canonical is obtained. An example is given to illustrate the application of the result.
