This paper studies the stability of coincident points for set valued mappings and proves their generic stability in the sense of graph topology.

研究了集值映象重合点的稳定性，在集值映象的图象拓扑的意义下，证明了其重合点的通有稳定性。

Generally, under the case of enough amounts and evenly distributed of coincident points, the accuracy of GPS height fitting can meet the requirement of the fourth order leveling network.

一般在重合点数量充足且分布均匀的情况下，GPS高程拟合的精度可达到四等水准网的精度要求。

It therefore is not warning of a new recession on the horizon, and their coincident index points toward ongoing economic growth.
