关于混沌磁场的正则回转变量的存在性
On the existence of canonical gyrokinetic variables for chaotic magnetic fields
摘要：
当寻找一种特殊类型的正则变量时，粒子动力学的陀螺运动学描述面临一个基本困难，即，即所谓的\textit{gyrokinetic canonical variables}。这些被定义在这样一种方式，其中两个分别与陀螺相位角，描述快速粒子绕磁场线的回转运动，其正则共轭动量识别。在本文中，我们打算讨论这些变量的存在条件。
英文摘要：
The gyrokinetic description of particle dynamics faces a basic difficulty when a special type of canonical variables is sought, i.e., the so-called \textit{gyrokinetic canonical variables}. These are defined in such a way that two of them are respectively identified with the gyrophase-angle, describing the fast particle gyration motion around magnetic field lines, and its canonically conjugate momentum. In this paper we intend to discuss the conditions of existence for these variables.
