摘要 从流动的电磁测量理论出发 ,用交替迭代的方法求解三维条件下复杂域的Laplace方程 ,得到含有一个气泡时电磁流量计权函数中虚电流势的分布 。 Based on the theory of electromagnetic induction flow measurement, the Laplace equation in complicated three dimensional domain is solved by using alternating method. Virtual current potential distribution is obtained for an electromagnetic flow meter with one spherical bubble inside. The result can be used to investigate the effect of the bubble size and the bubble position on the virtual current distribution and the resulted measurement error.
