To use the power calculation, you need an up-front approximation of the process variation for each response. This can be estimated from control charts or use a guess based on your subject matter knowledge. For each response, you should determine the minimum change in that response that you want the analysis to identify as statistically significant. Then, if you want to detect a change in the response that is equal to twice the standard deviation of the process, the power for 2 Std Dev should be at least 80%. If the power is low then you will need to do more runs (perhaps replicate the design) or adjust your expectations for the effect size you can detect

要用到能量衡算，首先要估算一下每一步反应的能量变化，可以从方程式或者再学科知识的基础上进行估算。对于每步反应，需要分析鉴别参与反应的在统计学上有重要意义的最微小的变化。如要探索反应中相当于标准的两倍的偏离，相应能量至少需达到两倍标准的80％。如果能量较低，就需要进行更多的计算(可能要修改设计方案）或者调整对检测到的结果的期望。

Design Evaluation calculates the probability of finding an effect of a given size (either ½, 1 or 2 standard deviations) for any specific design. This probability is called Power
不好意思，这是design expert中的句子，power 这里应该是什么意思？

应该是概率的意思吧，概率论里有这样的句子Power series and probability generating functions。
