# Fuzzy格上两种点式伪度量之间的关系The Relation of Two Kinds of Pointed Pseudo-Metrics on Fuzzy Lattice

Abstract: In this paper, we negative the main result that an Erceg pseudo-metric is a pointwise pseudo-me- tric in [1], point out the wrong reasons in the process of its proof, and further put forward the new conclusion that a pointwise pseudo-metric is an Erceg pseudo-metric, but the converse is not true.
