attraction force meaning in English

吸引力

The interaction between two surfaces is the result of repulsion and attraction forces .
两个表面间的相互作用是由于吸引力和排斥力作用的结果。
When the radian of rigid line reaches extensive magnitude , the presence of interfacial rigid line inclusion can change not only attraction force on dislocation arisen by soft inhomogeneity into repulsion force , but also the interaction effects between screw dislocation and soft matrix . soft inhomogeneity can repel screw dislocation in piezoelectric material due to their intrinsic electromechanical coupling behavior
当界面裂纹达到一定弧度时，可以将硬夹杂对位错的排斥作用改变为吸引；当刚性线夹杂达到一定弧度时，不但可以将软夹杂对位错的吸引改变为排斥，也可以改变软基体对位错的作用性质。
