[求助] 求教一个关于氮气吸附的问题,问了几个小牛也无法解决,谢谢!

在投稿过程,编辑问我以下问题,不知道如何解决。
   Surface area measurements with nitrogen are often limited by sensitivity - some additional clarification of the samples and quantities used would be useful.  It should be possible to add error bars from the fit to the adsorption isotherm - the three digit precision quoted by the authors in the paper is probably overstating things.
   
     在文中我们直接给出了氮气吸附数据,BET、孔分布以及孔容数据。用的是(The nitrogen adsorption-desorption isotherm measurements were performed on a Micromeritics ASAP 2010 volumetric adsorption analyzer at the temperature of liquid nitrogen.)
    讨论之后, 我们的回答是About BET results of the two species mentioned in our paper, we chose the data points between 0.05 and 0.2 (relative pressure) for the BET plot, which exhibit correlation coefficient of at least 99.99%. Accordingly, the error bars are about 0.01% of their specific surface areas, that is, 0.060 and 0.087 m2/g, respectively. Therefore, the BET results with the two digit precision is reliable in our paper.
     
     但是回稿之后审稿人说我会错意。。。给出的意见是    The author's have addressed most of the specific scientific comments that I have made.  The remaining one is error estimates for the BET results - once the isotherms are obtained it is possible to fit the low pressure region, and obtain error bars.

    现在有的朋友说可能涉及到不确定度的分析,但是真不知道咋搞这玩意儿,也不知是不是。。。谢谢!

     郁闷啊,大家帮帮忙!

现在美国一些杂志对测试的误差分析比较重视,我曾经在非晶固体杂志上也遇到过这个问题,专家认为你的测试会存在误差,一次与一次的测量也不会完全一致,需要对BET比表面积、孔体积和孔径等结构参数做误差分析。
