重力矢量及张量信息在地球重力场中的应用

Applications of Gravity Vector and Tensor in the Gravity Field

随着重力测量技术日新月异的发展,尤其是空间重力测量技术的发展,使反映地球中、高频信息的重力矢量及张量的获取成为可能。文中建立了基于重力矢量及张量信息求解重力场中扰动场元的数学模型,对于将来重力场的精化及其时变性的研究具有一定的理论意义。

With the fast development of gravimetric techniques, especially space gravimetry, it is possible to obtain gravity vector and tensor, which represent the middle and high frequency information of the gravity field. Mathematical models have been established based on the gravity vector and tensor in this paper, which would contribute to researching precise gravity field and time variation of the gravity field.
