摘　　要：对某盘孔结构原位涡流检查方法实施过程中影响检测灵敏度的情况进行了分析和试验,结果表明探头周向旋转与Z方向偏转均会影响检测灵敏度,其中原位检查中探头的周向旋转可通过工装得到有效控制,而为避免Z方向偏转带来的灵敏度差异,需在保证原位检查可实施的前提下,选择直径较大的探头以提高原位检查有效性。The effect of sensitivity in the process of hole structure in：situ eddy current inspection meth- od was discussed and tested. The results showed that the circumferential rotation and Z direction deflection of probe affected the detection sensitivity. The circumferential rotation of the probe could be effectively controlled by the fixture. To avoid different sensitivity caused by the difference of Z deflection, after the implementation of the in-situ inspection was guaranteed, larger diameter probe should he choosed to im- prove the effectiveness of in-situ inspection.
