向一阶导数 meaning in Chinese
u first derivative
Examples
- By comparing the aeromagnetic gradient data with the total field data , it can conclude that ; relative to aeromagnetic t , the gradient abnormality is more visible and it can be used to define the boundary of the magnetic bodies and the position of the fracture structure which could provide more information , especially the measured vertical gradient contain more abundant information than the calculated vertical 1st derivative
通过对航磁梯度和航磁总场资料的对比，发现航磁梯度场相对航磁t总场而言，异常更加明显；航磁梯度能更准确地确定磁性体的边界和断裂构造的位置，提供更多总场没有的信息，特别是实测的垂向梯度比计算的垂向一阶导数提供的信息更加丰富。
