摘　　要：应用电磁场理论,对引导磁场下铁磁性“药物”颗粒在靶向治疗中的受力和运动轨迹进行了分析和研究.得到了磁场、血流和血管壁对铁磁性“药物”颗粒的作用及运动规律.给出了铁磁性“药物”在靶向治疗中可采用的一种新方法———利用体外磁激励装置产生的变化磁场来实现铁磁性“药物”靶向治疗,还给出了采用这种方法实现靶向治疗的条件.This paper reports the systematic study of supporting forces and moving track of the ferromagnetic drug particulates in target therapy is performed using the electromagnetic theory. We have obtained the rules of action and effect of magnetic fields and blood stream and the wails of blood vessel on the ferromagnetic drug particulates. At the same time, we also give out the new method of magnetic drug targeting, namely, we make use of the magnetic navigating device located outside human body to produce the variable magnetic fields to realize magnetic drug targeting. The result of our research gives the conditions of carrying out magnetic medication target treatment.
