小子域滤波，适用于计算重力异常，具体算法请参照注释和相关文献（杨高印）。-Small subdomain filtering applied to calculate the gravity anomaly, the specific algorithm please refer to notes and literature (Yanggaoyin).

卡尔曼滤波的滤波器，是卡尔曼滤波算法的主要部分-Kalman filter filter, which is the main part of the kalman filtering algorithm

Energy cost of transmitting a single bit of information is approximately the same as that needed for processing a thousand operations in a typical sensor node. Thus, a practical way to prolong a wireless sensor network lifetime is to reduce the senso
