Experiment results indicate that the magnetic fluid flux has a direct relation with the magnetic field under the effect of traveling wave magnetic field. The bigger the magnetic field is, the more the flux is, when the structure of the magnetic fluid travellig pump and the saturation magnetization of magnetic fluid are constant. The volumes of the magnetic fluid from the travelling wave pump increase from 1.9 ml to 3.1 ml, when the magnetic field intensity increases from 25 900 A/m to 40 000 A/m. In addition, the change rate of the magnetic fluid decreases with the increase of the magnetic field due to the effect of magnetic field on magnetic fluid viscosity. The bigger the saturation magnetization of the magnetic fluid is, the more the flux is.

结果表明，行波磁场作用下的磁性流体流量与磁场的强度有直接关系：在磁性流体行波泵结构和磁性流体饱和磁化强度相同的条件下，磁场强度越强，其流量越大；当磁场强度从25900A/m增加到40000A/m时，单位时间内从行波泵内流出的磁性流体的体积由1.9 ml增加到3.1 ml；随着磁场强度的不断增加，磁性流体流量的变化率由于磁场对其粘度的影响而减小；而磁性流体的饱和磁化强度越大，其流量也越大。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.
