最近有篇文章审稿人提了一个问题：“Values with up to five (5) significant digits are presented for experimental superficial gas velocity. It is unlikely that measurements are that accurate. I contend that realistic values should have no more than three (3) significant digits. The same comment is applicable to Table 1 and anywhere else numerical values are provided.”

我原文这里的数字是这样的：“To make the bed operate in the bubbling regime, the superficial gas velocity was controlled between 1.166 cm/s and 12.831 cm/s with a step of 1.166 cm/s.”

如果保留三位有效数字就成了1.17 12.8 1.17，这样有效数字是统一了，但是我觉得是不是应该是小数点后保持一致啊？比如1.17 12.83 1.17。

谢谢！ 返回小木虫查看更多
