古埃磁天平法研究磁流体的磁性及稳定性

Gouy Magnetic Balance Measuring Ferro fluids'Magnetism and Stability

本文根据古埃磁天平的测量原理和磁流体的超顺磁性质，首次使用古埃磁天平研究了磁流体的磁性（磁化率和饱和磁化强度），利用磁流体的磁增重随时间的变化，研究磁流体的稳定性。

In this paper According to the Measuring principle of Gouy magnetic balance and the supermaynetism of ferrofluids,the Gouy magnetic balance tirst is used to measure the susceptibility and saturated magnetization dirst and compare the stabilities of two kinds of ferrofluids.This method is testified to be convenient and praetical.
