| Abstract: | Groupoids is a language very suitable for describing Orbifolds. This paper proved that the orbital space of the Groupoids＇ fiber product and the fiber product of the orbital space ara homeomorphism, and gave the homeomorphism relationship between fiber products in general global quotient Orbifolds. |
