This model couples the conservation of mass, momentum and species equations as well as water transport equation in the membrane.

刚ler研究了质子交换膜内水、温度和电流密度的分布。wangls和You[6] 分别对PEM燃料电池阴极内的汽液两相传质进行了不同侧重的研究。

The standard curve of correlation between membrane surface and fluorescence intensity of FPE was obtained by acid titration. The membrane surface pH was measured according to this curve.

在不影响膜结构的条件下，利用微量TritonX－100消除膜表面与介质之间的质子浓度差，通过酸滴定实验，能够得到膜表面pH与FPE荧光强度之间的相关曲线。

Through calculation of degradation activated energy and a comparison of damage effects, it was indicated that the addition silicone rubber had better resistance to proton radiation than that of the condensation rubber.

辐照降解活化能的计算和损伤效应的比较表明，加成型硅橡胶的耐质子辐照能力优于缩合型硅橡胶。

The result indicated that deoxidizing emeraldine destroyed of quinone diamide conjugate structure, both of the conductivity and solubility were reduced. The charge was delocalized along the molecular chains after protonic acid doped, which was beneficial to the electric conductivity.

结果表明，还原本征态聚苯胺破坏了聚苯胺链中的醌二亚胺的共轭结构，电导率和溶解性能均下降；质子酸掺杂本征态聚苯胺后分子链上的电荷离域程度增加，有利于电子流动，从而提高其电导率。
