核磁共振方法是一项尖端技术，在物理学和医学等领域有着较普遍的应用。 其无损性和高分辨率的特点是这项技术最大的优势。而利用核磁共振方法来找水 是其在地学中应用的一个新领域，为地球物理方法提供了新的思路。(NMR is a cutting-edge technology, medicine and other fields in physics and has more general application. The high-resolution non-destructive and are characterized by the biggest advantage of this technology. The use of NMR to come to learn that water is applied in a new area for geophysical methods to provide a new way of thinking.)

对加速度传感器采集的加速度数据进行二次积分，得出位移数据，并在几分过程中进行积分基线的标定，较精确。(The acceleration of acceleration sensors to collect data, a second integral part of displacement data, and in the process of integration, the more precise the baseline calibration.)
