The classical deterministic dynamics of a Brownian particle with a time-dependent periodic perturbation in a spatially periodic potential is investigated. We have constructed a perturbed chaotic solution near the heteroclinic orbit of the nonlinear dynamics system by using the Constant-Variation method. Theoretical analysis and numerical result show that the motion of the Brownian particle is a kind of chaotic motion. The corresponding chaotic region in parameter space is obtained analytically and numerically.

"破窗理论"是社会治安治理的一个重要理论。过去三十余年,"破窗理论"的提出在警察学界和犯罪学界引发了广泛而深入的学术讨论。威尔逊和凯林在彼得曼和津巴多研究的基础之上提出了"破窗理论",发现了无序行为与犯罪行为二者间的内在联系。无序行为与犯罪行为是否存在直接关联?这一问题引发了学术界赞成派和反对派的深入讨论。这些问题的讨论,深化了人们对无序行为与犯罪行为的理解,对社会治安的改善有着积极的促进作用。
