Abstract:[Purpose/significance] Taking the field of graphene as research object,this paper tries to further explore the time characteristics in the cross references of patents and papers[Method/process] Citation analysis method and patent bibliomatrics method are used to make the crossreference analysis of the patents and scientific papers in graphene fieldThe indices of science linkage,technology linkage,science cycle time and technology cycle time can reflect the interaction effects of patents and scientific papers quantitatively[Result/conclusion] The results reveal that science linkage is greater than technology linkage,and science cycle time is shorter than technology cycle time in the graphene research,which imply that the scientific theory research holds a dominant position in graphene studies
