Development trend analysis of variable oxygen concentration combustion research based on bibliometrics

Abstract

Based on CiteSpace, 955 journal literature related to variable oxygen concentration combustion research collected in the web of Science (WOS) core database were analyzed visually. The results show that: 1 Literature publication trends. According to the total number of published literature, it can be divided into three stages: initial development, steady development, and rapid development. 2. Analysis of the author’s co-occurrence map. The author’s cooperation network in this field is obvious, but the overall cooperation network presents a “core-edge” structure, and the cooperation of academic teams is scattered. 3. Research hotspots, the related research mainly focused on the combustion characteristics of polymer synthetic materials, and chemical cycle combustion related to the field of energy and power engineering. 4. Research on the frontier trend. At present, “mechanical property” and “Nanoparticles” are the keywords representing the latest frontier trend in this field.

Developing socio-hydrology: Research progress, opportunities and challenges

“…The data selected is based on the Science Citation Index Expanded (SCI-E) and Social Sciences Citation Index (SSCI) from the Web of Science (WoS) database. In order to obtain the most relevant literature data, the search topic is set as "sociohydrolog* OR socio-hydrolog* OR social hydrolog*" (Wang and Zhang, 2016). The least occurrences of the keyword to be shown in the co-occurrence map are set as 10.…”

“…It is noted that the explosive development of big data has enabled it to be applied in social science, policy, environment, water conservancy and many other fields (Chen et al, 2014). Based on the characteristics of big data technology and referring to its application experience in other fields, we believe that big data can also contribute to broadening the ways to obtain socio-hydrological data (Pei et al, 2020), finding laws from complex socio-hydrological processes (Wang and Zhang, 2016) and visualizing the results ( van Eck and Waltman, 2009).…”
