[求助] 60金币求助大侠看看审稿意见是什么意思

我做的干燥特性方面的研究,具体就是在用热重分析仪(TG/DSC)在线检测生物质颗粒质量和热量的变化,最后进行干燥动力学分析。
  审稿意见回来了,有几条怎么看都看不懂,请大侠帮忙看看这是什么意义。
1、Was the air flow rate of the TGA changed, to show, that the drying kinetics is independent from mass transfer by film diffusion?

2、A drying model for all temperature with one set of parameters describing drying for all experiments is scientifically far more interesting (applying multi variate regression). Fitting single sets of individual model parameters for every temperature is not "state of the art".

3、Re heat of water evaporation:
If e.g. potato are dried, more energy is necessary for the evaporation of water as the literature value for the evaporation of pure water. Additional energy is required to desorb the water molecules from the potato's matrix. As lower the water content is, as bigger is the ration qreal/dvH! It could be concluded, that this effect also accounts for drying of cotton stalk.

4、10.9% water content in wet basis was measured - how does this compare to the heat to evaporate this amount of water?

其他几条审稿意见提的都很尖锐,句句切中要害!有几个很棘手的问题,没人做、说不清、又难以实验论证,我在写论文的时候故意回避了这些问题,但审稿人很犀利,不仅把他们都提了出来,又指出了几个问题。看到这些审稿意见,我头都大了!真不知道怎么办?

1TGA的空气流量的变化能说明干燥动力学不受传质薄膜的影响吗?

专业不同,只大概看懂最后一条,大概是10.9%的数据是怎么出来的,和热蒸发比起来,这些数量的水是怎么得出来的。

第一个是你的TGA图有问题,让你解释下,第二个好像是你的参数太少了才一个,应该用多个参数描述你的那个模型,第三个水蒸发的对你实验的影响,第四条楼上已经解释了。总体感觉你的这个实验里水的蒸发好像对实验有很大的影响,直接影响到实验数据,所以才会提的问题都与这个有关。希望楼主多差些文献看看喽。不是很懂,上面只是自己的一点意见。希望对楼主有帮助哦
好好努力。

1、Was the air flow rate of the TGA changed, to show, that the drying kinetics is independent from mass transfer by film diffusion?

TGA空气流速的改变说明了干燥动力是不受薄膜传质扩散影响?


2、A drying model for all temperature with one set of parameters describing drying for all experiments is scientifically far more interesting (applying multi variate regression). Fitting single sets of individual model parameters for every temperature is not "state of the art".

所有温度的干燥模型以及一系列的参数来描述干燥实验更好。 单独的独立模型参数是不够的。

3、Re heat of water evaporation:
If e.g. potato are dried, more energy is necessary for the evaporation of water as the literature value for the evaporation of pure water. Additional energy is required to desorb the water molecules from the potato's matrix. As lower the water content is, as bigger is the ration qreal/dvH! It could be concluded, that this effect also accounts for drying of cotton stalk.

审稿人举了个例子,说明水能量需求和水含量的影响。应该是个建议,希望你考虑。

4、10.9% water content in wet basis was measured - how does this compare to the heat to evaporate this amount of water?
