电磁场 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.)

采用离散的数值方法，通过坐标转换并生成贴体网格系统，计算轴对称喷管流场(Discrete numerical methods, through coordinate transformation and generate body-fitted grid system, calculating axisymmetric nozzle flow)

通过卷积神经网络回归进行的图像配准，相比传统的图像配准算法，能更快地获得配准参数，也能更好地减小配准误差(Image registration based on convolution neural network regression can get registration parameters faster and reduce registration error better than traditional image registration algorithm.)
