Qualitative approach ...Qualitative and quantitative researches are two major approaches in the study of second language learning and teaching, each representing a special research method in the anthropological studies. Qualitative approach moves from data to a hypothesis while the quantitative approach begins with a postulate and ends in the testing of the postulate with data, as a result, it is reasonable to take the qualitative approach as an inductive method and the quantitative approach as a deductive method. These two approaches both have their advantages and disadvantages. While doing qualitative research the researcher should bear in mind the different background of the students tested. On the other hand, the researcher using the quantitative method often suffers the limitation imposed upon him or her by the predefined requirement of the experiment. Only an apt and suitable coordination of the two approaches can make the study of second language teaching and learning successful and fruitful.\;展开更多
目的系统分析食品抗菌膜领域的发展历程以及研究动态、热点和趋势。方法基于中国知网(CNKI)和Web of Science(WOS)数据库,采用CiteSpace可视化分析软件,对2000—2024年食品抗菌膜领域的文献进行量化统计分析。结果国内外发文数量稳步增...目的系统分析食品抗菌膜领域的发展历程以及研究动态、热点和趋势。方法基于中国知网(CNKI)和Web of Science(WOS)数据库,采用CiteSpace可视化分析软件,对2000—2024年食品抗菌膜领域的文献进行量化统计分析。结果国内外发文数量稳步增长,多见于食品领域高质量期刊;中国、伊朗和印度为主要发文国家,其中中国贡献最大,占比42.83%;研究主要集中在高校和科研院所,其中中国的江南大学(21篇)和伊朗的阿扎德大学(40篇)发文量居前,全球发文机构前10名中,中国占7席。该领域核心作者包括国内44位和国外37位;研究热点涵盖制备工艺、抗菌性能和应用效果,前沿领域聚焦于天然抗菌剂和抗菌性能研究。结论全球食品抗菌膜研究呈现稳步推进态势,研究深度和广度不断扩展,热度逐年攀升;中国在全球学术影响力显著,但仍有提升空间。该领域跨团队、跨国界的学术交流与合作仍显不足,未来需进一步加强;预计抗菌机理及性能研究仍是主要方向。展开更多
