    什么是sci的影響因子

    時間:2019年07月04日 所屬分類:期刊知識 點擊次數:

    SCI的影響因子是指該刊前二年發表的文獻在當前年的平均被引用次數,被引用次數越多,影響因子越高,說明期刊的影響力也越大,是用來衡量期刊的學術水平。SCI影響因子每年都會進行更新,對論文的發表的期刊影響因子有一定要求的,在發表論文前,要先查一下期

      SCI的影響因子是指該刊前二年發表的文獻在當前年的平均被引用次數,被引用次數越多,影響因子越高,說明期刊的影響力也越大,是用來衡量期刊的學術水平。SCI影響因子每年都會進行更新,對論文的發表的期刊影響因子有一定要求的,在發表論文前,要先查一下期刊的最新的SCI影響因子,以確保符所發表的期刊符合發表要求。

    什么是sci的影響因子

      那SCI的影響因子是怎么算出來的呢?相信許多朋友對此有疑問吧。其實,SCI影響因子是有計算公式的,通過公式就可以輕松算出影響因子。

      計算公式:IF(k)= (nk-1+nk-2) / ( Nk-1+Nk-2)

      說明:k 為某年,Nk-1+Nk-2 為該刊在前一兩年發表的論文數量,nk-1 和nk-2 該刊在 k 年的被引用數量。比如:某刊在2005年的影響因子是其2004和2003兩年刊載的論文在2005年的被引總數除以該刊在2004和2003這兩年的載文總數。

      最后,小編提醒大家在選擇投稿期刊時,根據自身的能力選擇適合的期刊,不要一味的選擇影響因子高的期刊,雖然它是對你學術水平最好的證明,可以在評職稱和升學時幫你拿到更高的分數,但是,SCI影響因子越高,相應的發表難度也就越大,不僅是對你專業技能水平的考驗也是對你英文水平極大的考驗。
