《云南建材》已创办多年，就文章质量而言，在我省４９种科技期刊中是不差的，但一直使我困惑的是其期发量一直偏低，没有充分发挥它的作用，深为该刊惋惜。看了《云南建材》近日写的改版报告，我对该刊一直期发量偏低的疑团迎刃而解。即：宣传面太窄，文章也过于偏重了专家。 “Yunnan Building Materials” has been established for many years, in terms of the quality of the articles, it is not bad in our province’s 49 kinds of sci-tech periodicals. However, what has always puzzled me is that the period of its occurrence has been too low and its full effect has not been achieved. Sorry for the magazine. Read the “Yunnan Building Materials,” the recent revision of the report, I have the period issue of the issue of low skepticism be solved. Namely: the propaganda surface is too narrow, the article is also too much emphasis on the experts.
