摘要
根据直流磁性冲击法的原理,在测量磁感应强度B之前必须先对冲击常数Cα进行标定。因此,Cα的准确测量就显得尤为重要。试验测量Cα受多种因素影响,通过正交试验法确定Cα,并使用标准样品对Cα进行校正,从而实现了对饱和磁感应强度Bs的精确测量。
According to the principle of ballistic method in direct current magnetic measurement, the ballistic con- stant Co should be accurately calibrated before measuring magnetic induction intensity B. There are many factors which influence the exact measurement of C,. Co is obtained by orthogonal test method and the Ca is calibrated using a standard sample. Finally, the high precise measurement of saturation induction density Bs is obtained.
