来稿时数据要求同一指标小数位数一致,一般按标准差的1/3确定位数,例如3.61±0.42,标准差的1/3为0.14,标准差波动在小数点后第一位,故应取小数点后第一位,写成3.6±0.4。又如8.61±0.27,标准差的1/3为0.09,故应取小数点后第二位,写成8.61±0.27,过多的位数并无意义。但在一系列 At the time of manuscript submission, the data required the same number of decimal places. Generally, the number of digits should be 1/3 of the standard deviation, for example, 3.61 ± 0.42, 1/3 of the standard deviation is 0.14, and the standard deviation fluctuates first after the decimal point Take the first place after the decimal point and write it as 3.6 ± 0.4. Another example is 8.61 ± 0.27, the standard deviation of 1/3 0.09, it should take the second place after the decimal point, written as 8.61 ± 0.27, too many digits does not make sense. But in a series
