一维亥姆霍兹线圈仿真，绕线区域由矩形生成，即长方体，更好的模拟了多匝线圈的情况。开发平台为comsol5.2(One dimensional Helmholtz coil simulation, the winding area is generated by rectangle, namely cuboid, better simulation of multi turn coil. The development platform is comsol5.2)

通过comsol软件，仿真得到平板电容之间的电场分布(The electric field distribution between plate capacitors is simulated by COMSOL software.)

本模型研究了在恒定频率下驱动的二维声悬浮器，几何结构作了一定程度的简化，弹性小颗粒在驻声场中均匀释放，确定了这些颗粒在声辐射力、黏性阻力以及重力影响下的路径。(In this model, a two-dimensional acoustic levitator driven at a constant frequency is studied. The geometric structure is simplified to a certain extent. Small elastic pa
