如何修改有效数字(significant digits)?
投稿后,编辑对我的有效数字产生了疑问(significant digits),我也详细发邮件询问了他,他给我解释了可是我还是不会改。
附件:编辑回信:
When you write
1.590 g/L Al(NO3)3, it means that you are certain that the true value is between 1.585 and 1.594. This means four significant digits, which is a high level of certainty. The uncertainty of this number is less than 1%.
When you write
0.017 g/L Ba(NO3)2, you are much less certain about the number (only two significant digits). This is an uncertainty of 10%.
Since weighing of chemicals should yield comparable uncertainties, you will have to round to a consistent number of significant digits, not digits after the decimal point.
我搞不懂编辑到底需要我怎么改?难道就只把表中的有效数字修改成一致就行了?请大侠赐教,我这样改的话对么?

应该是把有效数字位数统一。
你好,那请帮我看下我这样同意到3个有效数字的修正是否正确呢
,
祝福
编辑的话真是让我大开眼界......
应该按照你用的仪器精度进行保留有效数字,最后一位是估算值
仪器不是一般保留到小数点后几位吗?用有效数字怎么会靠谱?1000四位有效数字和0.0001000四位有效数字的准确率有的比吗?这个编辑666
我觉得你这样改是对的。这样有效数字都是3位了。
