The academic manuscripts of postgraduate students is an important source of contributions for the comprehensive sci-tech journals in colleges and universities. Thus

the comprehensive sci-tech periodicals in colleges and universities play an increasingly important role in the academic training of postgraduate authors. However

many postgraduate authors are not familiar with the writing norms of scientific and technological papers

which leads to format defects in their manuscripts. Moreover

there are some new revisions to the relevant standards and norms for the publication of scientific and technological journals

which are not known by postgraduate authors. Based on examples

this paper analyzes the common normative problems in abstracts

quantities and units

illustrations and tables

and references

in order to arise the attention of postgraduate writers. The postgraduate authors should standardize their paper before submission

so as to reduce the number of revisions

shorten the publication time

reduce the editing workload

and improve the quality and efficiency of editing and publishing.
