摘要

扩展的导心拉格朗日运动方程是在满足标准导心时空排序的随时间变化且不均匀的电场和磁场假设下，通过李-变换扰动法推导出来的。通过将极化漂移速度纳入导心速度以及在导心哈密顿和导心泊松括号中出现有限拉莫尔半径修正，将极化效应引入拉格朗日动力学。

Polarization effects in higher-order guiding-centre Lagrangian dynamics

The extended guiding-centre Lagrangian equations of motion are derived by the Lie-transform perturbation method under the assumption of time-dependent and inhomogeneous electric and magnetic fields that satisfy the standard guiding-centre space–time orderings. Polarization effects are introduced into the Lagrangian dynamics by the inclusion of the polarization drift velocity in the guiding-centre velocity and the appearance of finite-Larmor-radius corrections in the guiding-centre Hamiltonian and guiding-centre Poisson bracket.

期刊介绍： JPP aspires to be the intellectual home of those who think of plasma physics as a fundamental discipline. The journal focuses on publishing research on laboratory plasmas (including magnetically confined and inertial fusion plasmas), space physics and plasma astrophysics that takes advantage of the rapid ongoing progress in instrumentation and computing to advance fundamental understanding of multiscale plasma physics. The Journal welcomes submissions of analytical, numerical, observational and experimental work: both original research and tutorial- or review-style papers, as well as proposals for its Lecture Notes series.
