Teaching import and export on partial order relation in Discrete Instructure Mathematics

Given the features that Discrete Instructure Mathematics have Strong theory, the abstract content, and independent Sections, the paper proposed that teaching in expensive, not in too many. The article takes partial order relation as an example to explain how to cayrry on teaching import and export. By studying partial order relation, students´ abstract thinking ability get improvement largely. By fine introduction of partial order relation, student are in the hands of the knowledge of Discrete Instructure Mathematics firmly. Thus, students will have a deep impression to the course.
