| 摘 要： | 在前人推导长方体重力场正演理论表达式工作的基础上，系统总结了现有长方体重力异常正演理论表达式；借鉴长方体磁异常正演理论表达式推导中积分求解方法，重新对长方体重力场正演理论表达式进行理论推导，提出了两种全新的长方体重力异常正演公式形式，并给出了全部的积分求解过程，对比模型正演计算结果表明，新导出长方体重力场正演理论表达式的正确。

| Abstract: | On the basis of study on gravity and magnetic anomalies due to a homogeneous rectangular prism,we deduce expressions for gravity field due to a homogeneous rectangular prism,and obtained new analytical expressions for computing gravity anomalies caused by a cuboid.Expressions for gravitational attraction of a homogeneous rectangular prism are developed explicitly.Comparison with forward calculation of models shows that,these new expressions are correct. |

| Keywords: | rectangular prism gravitational field forward calculation integral |
