This paper introduces the types,use and using objects of Chinese fire-retardant coating at present,reveals inclusive chemical knowledge,analyzes the developing status of fire-retardant coating,and discusses the future developing trend of fire-retardant coating.

Based on the concept of green chemistry,this paper introduces the research advance of unconventional medium of organic reaction,such as water,supercritical fluid,ionic liquid,fluorous medium etc.

In recent 30 years,research of chemistry teaching art in China mainly focused on teaching skills and artistic skills,and made significant progress.In which,there are still some problems such as lack of research on formation mechanism of teaching art,weakness of theoretical basis,lack of chemical characteristics,unbalance of relation between teaching and learning,and singleness of research methods.To solve these problems,research field should be expanded and research methods shuould be broadened.
