| 摘 要： | 采用自制的试验设备研究了磁流体的粘度与外加磁场及温度的关系。结果表明：磁流体的粘度随温度的增加而减小；当环境温度一定时，在磁场的作用下磁流体的粘度会增加，粘度的大小与磁场作用的时间有关；磁场作用达到一定时间后，磁流体的粘度达到稳定；随着磁场的增加，磁流体的粘度增加，当磁场达到一定强度后粘度不再增加。

| Abstract: | The effect of magnetic field and temperature on the viscosity of magnetic fluid was studied. The viscosity was reduced with increasing temperature. When the temperature of the surroundings was kept constant, the viscosity of magnetic fluid increased with increasing the magnetic field. This change was related to the magnetic intensity and acting time. When the acting time was increased to a certain value, the viscosity tended to a constant value, If the applied field was kept constant, the viscosity tended to be steady with increasing time. When the magnetic field was increased to a certain value, the viscositv tended to a constant value. |
