| Abstract: | The purpose of this paper is to study the time-integral theorems for the Birkhoff systems. A time-integral identity of the systems is presented. The power-like equation, the Pfaff-Birkhoff integral variational principle and the Pfaff-Birkhoff-d′Alembert differential variational principle of the systems are deduced by using the time-integral identity. |
