CHD-6核子旋进磁力仪是数字显示直读磁场总向量绝对值的仪器，其性能及操作方法比普通磁秤优越，目前已有不少单位使用此仪器作地面ΔT磁测，并取得了良好效果。能否用CHD-6核旋仪取代磁秤作岩石标本磁参数的测量呢？我们进行的实测试验表明：用核旋仪侧磁参数不但操作简便，其灵敏度及精度都比普通磁秤方法要好些。下面讨论其理论依据和具体方法。
CHD-6 nuclear precession magnetometer is a digital direct reading magnetic field vector absolute value of the instrument, its performance and operation method superior to the ordinary magnetic scale, there are many units using this instrument for ground ΔT magnetic measurements, and made Good effect. Is it possible to replace the magnetic scale with the CHD-6 nuclear spinodger to measure the magnetic parameters of rock specimens? Our experiments show that: the use of nuclear magnetic parameters side of the instrument is not only easy to operate, its sensitivity and accuracy are better than the ordinary magnetic scale method. The following discusses the theoretical basis and specific methods.
