磁性流体在外加磁场的作用下改变其结构，磁场去除后不恢复到初始状态。假定在受磁场作用的流体中形成的团簇在磁场移除后仍然存在。通过分析超声波吸收系数的变化，研究了铁磁流体性质与磁史的关系。
The magnetic fluids change their structure under the influence of an external magnetic field and do not return to the initial state after the magnetic field removal. It is supposed that the cluster formed in the fluid subjected to a magnetic field remains after the field has been removed. The resulting dependence of the ferrofluid properties on its magnetic history has been studied by the analysis of changes in the ultrasonic wave absorption coefficient.
