向量分析与场论基础
《向量分析与场论基础》就是关于场的数学刻画、描述以及场特征的一般分析。在本概要中,为简明区分向量与标量起见,向量一律采用黑、斜体。
(vector analysis and electromagnetic field theory based "vector analysis and field theory foundation" is on the mathematical characterization. and the description of the general characteristics of the market analysis. In the outline for concise distinction between vector and scalar sake, vector will be used black, in italics.)
