Abstract: In the configurational space，there is no inference pattern formed by independent point，line segment， square-like and their array wave functions because there is no overlap between different parts of them. However， in the momentum space，the inference patterns can be constructed respectively. Results show that，along with the increase of the independent parts，the interference pattern tends to be localized with some fine structures in it. Studies of these inference pattern can be helpful to understand quantum mechanics.

Key words: array-like wave functions, momentum space, uncertainty relation, interference pattern
