审稿意见的原文如下，不明白的地方（标黑）求各位解答
Since CDs are “selectors” optimizations should not be done in terms of Rs but also using “selectivities” (alphas), or any other optimization criterion based on mobilities.
这个基于淌度的其他标准是指什么是指迁移时间么？

CD concentrations are two (new) separation variables as it also are pH, voltage, ionic strength, or injection volume. This is an interesting and novel proposal. There are two conceptual lines that could be followed to optimize them: investigating the dependencies of the mobilities on the different variables - e.g. mu vs , mu vs , mu vs pH, etc... - to compose a model predicting mu=f (, , pH, etc) to finally optimize mathematically - e.g. by maximization of predicted selectivities between all pairs-, or exploring empirically all the responses in all the domains of the selected variables - e.g. selectivities between all pairs at different levels within the domains of the selected variables - e.g. experimental selectivities vs (, , pH, etc..)-
这段中的mu是指前文中的mobilities及淌度么？我若是补充图表，做各化合物迁移时间与变量之间的关系图可以么？
请各位指教，谢谢大家！
