The results of theoretical analysis and emulation experiments indicate that the H∞filter and the adaptive Kalman filter are both effective in alleviating the effect of gravitational anomaly, but the adaptive Kalman filter is better than H∞filter in filtering behavior.
理论分析和仿真实验表明:H∞滤波算法和自适应卡尔曼滤波算法都具有较好的滤波收敛特性,并能在一定程度上有效地消除重力异常畸变对重力异常测量精度的影响,但自适应卡尔曼滤波的性能优于H∞滤波。

For indeed it is a most poignant area of gravitational anomaly and thus time-space dimensional concentricity.
更确切说来这是一个重力异常最突出的一个地方，因此时空在维度上比较集中。
Tt is suggested in this paper that the calculation of the gravitational anomaly is performed by boundary elements method, curvilinear integral is for 2-D object and surface integral for 3-D object.
本文提出用边界单元法计算重力异常，二维形体用线积分，三维形体用表面积分。
Finally, deep faults and seismicity as well as the gravitational gradient zone of the East China related to the deep anomaly are discussed primarily.
最后，对东部梯度带、深断裂、地震活动与重力异常的关系，进行了初步讨论。
