Archaeologists also may locate buried remains by using such technologies as ground radar, magnetic-fieldrecording, and metal detectors.
考古学家们还可能利用地面雷达、磁场记录和金属探测器等技术来定位被掩埋的遗骸。

It is necessary to compensate for the demagnetizing field in remanence measurements of perpendicular magneticrecording films.
对于垂直磁记录薄膜，进行剩余磁化强度的测量时，必须补偿退磁场。
