求教:有效數字和小數位數的問題 已有1人參與

如題,近日文章來修改意見,如下: 7)Many results are reported with unreasonably large number of significant figures. This should be revised throughout the whole manuscript. Just as an example, in page 16, a recovery is reported as 93.15±2.41 %. This should be reported instead as 93±2 %, which is the correctly conservative way of reporting figures. Many more examples appear here and there, especially in Table 4. 8)Table 5, again too many significant figures for LOD and LOQ. Since these two parameters are computed as a function of uncertainties (see the corresponding equations), they should be reported with 1 or at most 2 significant figures, because the noise cannot be estimated with more than 2 figures, and this is the limiting factor in the number of significant figures of the LOD and LOQ. 9)And I guess 5 significant figures is too much for some of these SEN figures. significant figures是有效數字的意思嗎??我當時所有的數據都是保留小數點后面兩位,比如SEN=583.25,就是五位有效數字,再如SEN=3653.25,六位有效數字,太多??保留兩位有效數字,用科學計數法嗎? 另外,LOD=0.001,保留兩位有效數字要寫成LOD=0.00010,這么多小數位數??猶如,LOQ=15.6,保留兩位有效數字寫成LOD=16??這么粗糙??? 暈了,到底是按小數位數算好,還是按有效數字算好呢?? 求指教。 謝謝。! |
