航天电子设备归零中多余物定位排查的探讨

Discussion on the Positioning of Redundant Objects in Zeroing of Aerospace Electronic Equipment

在航天电子设备归零中,由于多余物存在发现难、定位难、复现难等问题,导致归零存在定位不准确的可能。为避免归零过程中出现多余物定位不准确的现象,结合实践对航天电子设备归零中定位为多余物的必要条件和充分条件进行了探讨,并给出了可能造成定位错误的情形,对多余物归零过程提出了建议。

Redundancy occupies a certain proportion in the quality of aerospace electronic equipment.Because the redundant objects are difficult to find,locate and reproduce,there may be a possibility of"false zero".In order to avoid the phenomenon of"pseudo-zero"of redundant objects,this paper,combined with practice,discusses the necessary and sufficient conditions for positioning redundant objects in the electronic equipment,clarifies the situations that may cause pseudo-redundant objects,and puts forward some suggestions for the process of positioning redundant objects.
