Results show that, conventional point dipole model has overrated the magnetic-induced shear modulus of the magnetorheological elastomers.
计算结果表明，传统的点偶极子模型高估了磁流变弹性体的磁致剪切模量；
But if the goal is to reproduce sounds accurately, then a speaker must be either an acoustic point source (monopole, omni-directional) or an acoustically small bi-directional source (dipole).
但是，如果目标是精确的重放声音的话，一个扬声器必须是声学上的点声源(单极点，全向响应)，或者是一个声学上小的双向源(偶极)。
This article gives a description of a method to ascertain the magnetic field at any arbitrary point of magnetic dipole space by a kind of reciprocity principle.
