螺栓节点中的prying force、prying action是什么意思？

Prying force—additional tensile force developed as a result of the flexing of a connection component in a connection subjected to tensile force. External tensile force reduces the contact pressure between the component and the base, and bending in part of the component develops a prying force near the edge of the connection component.
撬力—因承受张力的连接中的连接部件挠曲产生的额外张力。外部张力减小了部件与基座之间的接触压力，而部件部分的弯曲在连接部件附近产生撬力。
