虽然大多数机器和变压器中的电磁问题可以使用2维或准j维公式进行满意的研究，但有些情况需要全j维解来避免对建模准确性的怀疑。在考虑了适用于j维涡流问题的方法后，选择了向量电势(T)和标量磁势(n)的联合方法，即通常所说的“T-fl法”进行开发。它的优点是边界条件很容易指定，并且所需变量的数量很经济：这些优点的产生是因为问题被分为“电”和“磁”区域的方式，以及T在非导电区域为零或常数的事实。该方法的基础最初由Carpenter[1]， L2]和一个阶段描述
Although the majority of electromagnetic problems in machines and transformers can be investigated satisfactorily using a 2-or a quasi-j-dimensional formulation, some situations require a full J-dimensional solution to avoid doubts about the accuracy of modelling.Following consideration of methods applicable to j-dimensional eddy current problems, the combined electric vector potential(T) and scalar magnetic potential (n) approach-commonly known as the" T-fl method"-was selected for development. Its advantages are that boundary conditions are easily specified, and it is economical in the number of variables required: these advantages come about because of the way in which the problem is divided into" electric" and" magnetic" regions, and the fact that T is zero or constant in non-conducting regions. The basis of the method was originally described by Carpenter[I], L2], and a stage
