Thermal conductivity is measured by the transient hot-wire method, which shows that the thermal conductivity increases with the increase of nanofluid particle volume fraction and temperature. The thermal conductivity of 0.3vol% SiO2-water nanofluid increases by 11.5% at 25℃, while it increases by 46.5% at 50℃ when compared with water at the same temperatures.

Barrel is the key part of artillery. In shot process, propellent gas of high pressure and high temperature flows in the tube at a high rate of speed, which brings an upheaval to the temperature field of the composite barrel. As to the composite barrel with metal inner, its poor thermal conductivity is more likely to cause uneven temperature distribution and bigger temperature gradient, to produce improper deformation and to make the work temperature of metal inner rise, all of which will affect the life span of barrel.
身管是火炮的关键部件,在火炮发射过程中,高温、高压的火药燃气在身管内成脉冲式高速流动,使身管受到急剧的加热,引起身管壁内的温度急剧变化,而对于带金属内衬复合材料身管,由于复合材料导热性能较差,更容易引起非均匀温度分布以及较大的温度梯度,产生不合适的变形,也会使身管的金属内衬的工作温度升高,从而使得身管的寿命降低,同时身管的发热会引起其刚度的变化,增大射弹散布。

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。

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.
对于土体的温度和吸力变化特征,采用Wilson提出的理论加以描述,在此理论中,分别利用Darcy和Fick定律描述水和蒸汽的流动规律,土水特征曲线和水力传导系数假定仅仅相关于非饱和土吸力,水的潜热系数是温度的线性函数,温度传导系数采用De Vries建议方程加以计算。
