| 摘 要： | 建立了两个新的低维量子系统模型－斜磁场作用下的直三角和等腰三角量子阱中电子运动模型，借助如莱截面方法对此模型进行了数值计算，数值结果表明在一定的磁场倾斜范围内存在着混沌，并通过此模型讨论了与对称性的关系。

| Abstract: | Two new models in low-dimensional system is offered and studied,which are the models of eletronic motion in trigonal potential well subjected to a tilted magnetic field.Numeric calculation is done by the poincare surfaces of section.The numeric result show that the system represented by each model is chaotic in a certain scope of tilt angle.The connection between chaos and symmetry is also argued. |
