The analysis of polymer structure indicates that the non-crystalline phase is the majority of the agglomerate structure and the crystalline phase is the minority, the highest crystal value only reaches the level of 0.1646;There is a definite interactionadditives and PVA, which not only reduces the crystal value of ASPE to make amorphous areas enlarge but also improve the ability of segmental motion by destroying the well-regulated and orderly character of polymer chain, meanwhile restricts the mobility of potassium cation and enhances the anionic transference number of hydroxide ions, all these improve the ionic conductivity;The ionic conductivity occurs essentially within the amorphous phase of the ASPE;The structure of ASPE doesnt change in the range of our test temperature, this means, the temperature only takes effect on degradation of complex in certain compositions, ionic mobility and segmental motions of the polymer chain.

聚合物结构分析表明：碱性固体聚合物电解质中凝聚态结构以非晶态为主，仅有少量的晶态，结晶度最大为0.1646；添加的各组分与PVA之间都有一定的相互作用，这种作用不仅破坏了聚合物链段的规整性，能够降低聚合物的结晶度，增大无定形区域，提高链段运动的能力，同时这种作用限制K~+离子的运动，提高OH~-的迁移率，从而提高离子电导率；碱性聚合物电解质的离子传导主要发生在无定形区；在本实验测试离子电导率温度范围内，聚合物内部的结构不会发生变化，即温度只会影响电解质内部络合物解离程度和载流子迁移以及聚合物链段运动的情况。

In this paper,a modified Arrhenius equation was proposed,based on the measurement and analysis of the conductivity for three kinds of Y2O3-stablized ZrO2,to describe the temperature dependence of the ionic conductivity.

The theories proposed by Wilson (1994) were adopted to describe the fundamental behaviors of temperature and variation of suction of soil. The Darcy's law and Pick's law described the flows and evaporation of water respectively. Some proposed assumptions including the characteristic curve of volumetric water content and hydraulic conductivity were only related to the suction of unsaturated soil. The coefficient of latent heat for water was a linear function of temperature; and the heat conductivity was calculated according to the equation proposed by De Vries.
