With　the　explosive　growth　of　data　and　the　rapid　development　of　artificial　intelligence(AI)　technology,　scientific　research　requires　to　process　a　large　amount　of　information.　Recently　AI　tools　based　on　large-scale　language　models　(LLM)　have　emerged,　providing　researchers　with　new　problem-solving　ways.　In　this　paper,　we　focus　on　the　application　of　AI　tools　in　the　field　of　scientific　research,　and　conduct　a　comprehensive　analysis　of　LLM　-based　AI　tools.　Firstly,　we　introduce　different　types　of　LLM　softwares　and　analyze　their　characteristics　and　advantages.　N　ext,　we　select　some　typical　cases,　explore　the　value　and　limitations　of　these　tools　in　practice.　Moreover,　we　summarize　the　main　findings　of　the　existing　study　and　suggest　some　possible　research　directions　in　future.　It　is　expected　that　this　paper　can　provide　reference　and　guidance　for　the　use　of　AI　tools　in　scientific　and　educational　research.　　©　2024　IEEE.
