The self-attraction effect (SAE) is an important systematic error in a high-precision atom interferometry gravimeter, which has been researched. In this paper, we use the finite element method (FEM) to calculate the SAE of an atom gravity gradiometer. In this way, the SAE of the gravity gradiometer is accurately determined, and the calculation result shows this effect is 235(8) E (1 E = 1 ##IMG## [http://ej.iop.org/images/0026-1394/57/4/045011/metab5830ieqn001.gif] ) in the atom gravity gradiometer. Based on this calculation, this effect in many high-precision experiments can be corrected.

原子重力梯度仪中的自吸效应

自吸效应（SAE）是高精度原子干涉重力仪中的重要系统误差，已得到研究。在本文中，我们使用有限元方法（FEM）来计算原子重力梯度仪的SAE。这样，可以精确地确定重力梯度仪的SAE，计算结果表明该效果为235（8）E（1 E = 1 ## IMG ## [http://ej.iop.org/images/ 0026-1394 / 57/4/045011 / metab5830ieqn001.gif]）在原子重力梯度仪中。基于此计算，可以纠正许多高精度实验中的这种影响。
