摘要
利用同种磁性液体表面张力智能测试仪在不同边界条件下对磁性液体的表面张力系数进行了测试,实验结果表明,磁性液体的表面张力系数与磁场强度及其饱和磁化强度成正比。利用不同的仪器、在相同边界条件下对同种磁性液体表面张力系数测试的结果表明,智能仪器能够准确获取磁性液体液膜断前、断后的电压值,减小依靠人眼盲读电压值产生的误差,测试精度比传统仪器提高了4.14%。
Abstract. The surface tension coefficient of the magnetic fluids was measured with the magnetic fluids surface tension intelligent tester under different boundary conditions. And the results show that the surface tension coefficient of the magnetic fluids varies directly as the magnetic density and the saturation magnetization. The test results for the magnetic liquid surface tension coeffi- cient by different instruments under the same boundary conditions show that the magnetic fluids surface tension intelligent tester can record the voltage before and after the break of the magnetic fluids membrane, reduce the measured error read by eyes and enhance the accuracy by 4.14% compared with the traditional tester under the same boundary conditions.
