所以在我们测量之前,一定要先了解不确定度。
So whenever you make a measurement you must know the uncertainty.
本文提出了应用不确定度的概念。
不确定度是测量质量的重要指标。
The uncertainty is an important index for measurement quality.
计算出压力表的总的不确定度和自由度。
Calculate out total uncertain degree and degree of freedom of the manometer.
用不确定度可以评估回弹值测量的质量。
And the uncertain degree of quality that can assess the resilience value and measure.
现在知道测量过程中，不确定度的重要了吧？
Do you see now how important it is that you have uncertainties in your measurements?
现在知道不确定度，在测量中有多重要了吧。
进行了不确定度分析。
本文简要介绍了风洞数据不确定度分析方法。
This paper briefly presents a method of uncertainty analysis for wind tunnel test data.
当不确定度到那么大的数值时，你不知道谁是第一个到达的。
When the uncertainty gets that big, you don't know which came first.
什么是不确定度？
从实验结果看，测定值的相对标准偏差小于0 7%，相对不确定度小于0 5%。
Under experiment condition, RSD is less than 0.7%, reference uncertainty is less than 0.5%.
从实验结果看，测定值的相对标准偏差小于0 7%，相对不确定度小于0 5%。
Under experiment condition, RSD is less than 0.7%, reference uncertainty is less than 0.5%.
