[求助] 荧光粉 误差方面的问题已有1人参与

精修数据,衰减数据没有误差,怎么办

Line 98: a=b=9.7453Å, c=7.2895Å, and the cell volume was obtained as 692.2902 Å

The results are given without errors - without estimated standard deviations these values are meaningless.

Line 172-173: The calculated decay times are determined to be 37.516, 37.270, 36.412, 32.633,
28.234, 27.392ns for SLP: 0.003Ce3+, xMn2+phosphors (0=x=0.09).

The decay times are based on fits of experimental data and are NOT calculated decay times.
The decay times are given without errors - without estimated standard deviations these values are meaningless.
各位大神帮帮忙,这个问题怎么答,我看大家写都没误差啊
