【Abstract】 In this paper, the Poincare and Poincare-Cartan integral invariants in nonconservative systems are established. According to the integral invariant, the non-linear oscillation of particles in 3-folded symmetry spiral sector cyclotron is investigated. It turns out that the method is successful.更多还原
