重庆师范大学硕士学位论文英文摘要The Movements of Charged Particles in Electric andMagnetic Fields and the Solutions of Electromagnetic ForceABSTRACTStudy the movements of charged particles in the electric and magnetic fields with agreat significance in many important areas of physics and scientific technology.Forexample,the applications of mass spectrometers,oscilloscopes,TV picture tubes,particle accelerators and other equipments are closely related to this study.In addition,study the movements of charged particles in the electric and magnetic fields havebecome an important component of the theory research in plasma physics.Many peoplecarried out a lot of work about the movements of charged particles in the electric andmagnetic fields.Most previous work basically started from the theory of classicalelectromagnetic field and classical mechanics to study the classical track of chargedparticles,but few people analyzed the situation of flexible interface when it existed.This article will both consider the condition of the existence of a flexible interface andthe classical and relative motion of charged particles,and then use the quantum theoryto solve the particles'Schrodinger eigen equation.This article will introduce the solutions of the Laplace equation when the magneticscalar meet it and the Helmholtz equation when the electromagnetic vector satisfy it.This paper also solves the electromagnetic field through the use of boundary valueproblem and calculates certain electromagnetic force through the application ofMaxwell stress tensor.Research results of this project have a great referencesignificance to explore and expanse new areas of the application of electromagnetictheory.This article focuses on five aspects,it is arranged as follows:1.The classical movement of Charged particles in electric and magnetic fields.2.The relative movement of Charged particles in electric and magnetic fields.3.The movement of Charged particles in parallel electric and magnetic fields andnear the flexible interface.4.Solutions of the Laplace equation when certain magnetic scalar meet it and theHelmholtz equation when the electromagnetic vector satisfy it.5.Calculate certain electromagnetic force by the application of Maxwell stress
