光强高斯分布对散焦相差的曲率信号影响较大，信号百分比误差达到25%，对其他相差的曲率信号影响很小；

Intensity of Gaussian distribution impacts significantly the sensing signal of the defocus phase, in which the error percentage achieves 25%, but for other phase profile, the effect is ignorable.

这个指标描述了由异质性而非抽样误差引起效应变异的百分比。

This describes the percentage of the variability in effect estimates that is due to heterogeneity rather than sampling error (chance).

采用滤波法进行功率谱分析，不存在数据截断带来的误差，还可方便地用于等百分比带宽的谱分析。

But the filter method avoids the error caused by truncated data and it can achieve the analysis of a fixed percentage bandwidth easily.

So this is the percent error and what you see here is that if the number is below the zero line it means people underestimated the calories, and the bars that go above means people overestimated the calories.

这是百分比误差,你们看,如果数字低于零,这表示人们低估了卡路里,高于零表示人们高估了卡路里
