This paper gives the metrizable conditions of 2-probabilistic metricspace (2-pm space), its distance function and pseudo distance function, thus extends some conclusions of PM-space to 2-pm space.
In this paper, the pointwise pseudo-orbit tracing property is defined on a compact metricspace, and it is a generalization of pseudo-orbit tracing property.

The conceptions of DL3-similarity degree and pseudo-metric on two formulas are given. DL3-logic metric space is built. And it is proved that this space has no isolated point.
