| 摘 要： | 利用矿物在相同磁场、相同质量下因w(Fe3O4)不同会有不同称重读数,采取不同磁场类型和不同磁场强度对配料进行磁一重效应实验.结果表明,在一定磁场条件下,w( Fe2O3)对磁一重实验结果准确性的影响可以忽略,各实验条件下磁一重效应拟合直线方程决定系数均大干0.996,线性相关明显,磁一重效应可以准确便捷测定矿物中Fe3 O4的质量分数.

| Abstract: | Minerals with same total mass but different w(Fe3O4)will show different weighting readings under the same magnetic field condition.Accordingly,experiments are carried out to test the magnetic-gravity effect in different types and intensities of magnetic fields using diverse testing samples.The results show that the influence of w(Fe2O3) on the accuracy of magnetic-gravity effect can be ignored under a certain magnetic field condition.The determinative coefficients in the magnetic-gravity effect fitting equations are higher than 0.996,which shows excellent positive correlativity.The mass fraction of Fe3O4 in diverse minerals can be determined accurately and conveniently by using magnetic-gravity effect. |
