Based on the characteristics represented by the consumers of fmcg industries in purchasing and some problems existing in the current distribution channels , this paper advances some countermeasures for the deep distribution of the distribution channel of fmcg 根据快速消费品行业消费者在购买时所表现出的特点及现有渠道中存在的问题,提出了快速消费品分销渠道深度分销的对策。
The surfaces of the rivet and the plate are partitioned into triangular cells , the current distribution on the patches is represented by subdomain - type basis function , the efie is translated into matrix equation by the galerkin method , then the current coefficient are obtained 铆钉和平板表面采用三角形面元进行剖分,面元上的电流分布用子域基函数表示,用伽略金法将电场方程转化为矩阵方程求解电流系数。
In the far field , the farther the distance , the similar and less distance dependent of the image and radiation pattern of electric and magnetic field , the similar the image of electromagnetic field to the fourier transform of the source current distribution , the less distance dependent of the radiation pattern 在越远之远场中,电场与磁场之影像及场型越相似,距离越远差异越小,电磁场之影像越近似于电流源分布之富氏转换。
Abstract : based on principle of minimal leakage magnetic field energy for current distribution of parallel coils in the primary side of transformer and also on finite element method , the method for calculating the current distribution of parallel coils in the primary side is studied and solved 文摘:以变压器一次各并联线圈的电流分配一定满足漏磁场能量最小原理为基础,结合有限元方法研究了计算一次各并联线圈电流分配的方法。
In the near field , the image and radiation pattern of electric and magnetic field are different and varies with distance , the image of electric field is similar to the charge distribution of the source while the image of magnetic field is similar to the source current distribution 在越近之近场中,电场与磁场影像及场型各不相同,距离越近差异越大,电场之影像越近似于电流源之电荷分布,磁场之影像则越近似于电流源之电流分布。
