摘　　要：用正则变换、复平面展开、泰勒展开3种不同的方法对磁场矢函的表达式进行推导,得出3种磁场矢函表达式。对3种磁场矢函表达式进行了比较分析。在一定的条件下,3种表达式可以写成统一的表达式。在实际的研究中,可根据具体情况选择适当的表达式。Vector potential and expanded forms of magnetic field play a very important role in accelerator physics investigation. Begin with the different expended forms of vec- tor potential, the Laplace equation of vector potential is solved and three general expres- sions used in accelerator physics are obtained. In addition, the difference of these ex- pressions and the influence caused by the difference are presented. As a conclusion, the applications of these expressions are also given.
