First by testing the practical multilayer insulation in a cryogenic tanker, which is the carilometer in my paper,some affecting factors on multilayer insulation are analysed, then by using the low-temperature and vacuum environment caused by multilayer insulation, the effective thermal conductivity of multiple fiber paper with 5 layers is tested.Through Newton interativemethod,an empirical formula is deduced to computer the thermal conductivity of fiber paper,The errors between experimental thermal conductivity and the calculated conductivity by empirical formula are below10%,so the formula of fiber conductivity can be applied to practical enginnering.

为探索改善工程应用中高真空多层绝热层绝热性能的方法，本文实验研究中首先测量了包扎在实际低温储罐上不同结构的高真空多层绝热层的绝热性能，并分析了环境温度、环境压力，层数、不同隔热材料的组合等因素对工程应用中的高真空多层材料绝热性能的影响；然后利用多层绝热层中的低温真空环境测量5层干法纸在不同温度区间内的表观导热系数，在有限实验数据的基础上用牛顿迭代数值拟和出计算5层干法纸表观导热系数的经验公式，对比经验公式计算值和实验测量值，发现二者的误差在10%以内，因此在工程应用中可用本文的经验公式计算干法纸在低温下的导热系数。

The difference of bulk density of coastal soils took an effect on infiltration rate and diffuse rate. The infiltration rate and diffuse rate of coastal soils which bulk density was small were big. The water transmitting experiment of coastal soils showed that the saturated conductivity of different layers in soil profile were great, and the saturated conductivity of undisturbed soil was highly higher than that of disturbed soil. The saturated conductivity of coastal soils embanked earlier was lower than that of coastal soils embanked later. Under different water content, the unsaturated conductivity of coastal soils had a great change and the bulk density had an effect on unsaturated conductivity. The soil with a low bulk density had a high unsaturated conductivity. Chlorine ion moved in coastal soil was an inert ion. The distribution of CU in soil was definite and repeated, which is no relation with the time and velocity of infiltration. The concentration of infiltration solution and the texture of coastal soils had no apparent effect on solute movement synthetic dispersion coefficient, while bulk density took an apparent effect on solute movement synthetic dispersion coefficient. Synthetic dispersion coefficient of coastal soils increased as bulk density decreased.

与thermal conductivity相关的网络解释 [注：此内容来源于网络，仅供参考]

thermal conductivity：热导率

(23)热导率(Thermal conductivity)热导率过去称为导热系数或热传导系数,反映物质的热传导能力. 即在物体内部垂直于导热方向取两个相距1cm,面积为1cm2的平行平面,如果在这两个平面温度相差1K,则在ls内从一个平面传导到另一平面的热量就规定为该物质的热导率,

thermal conductivity：导热性

导热性 导热性(Thermal Conductivity)对固体或液体传热的能力的衡量 金属的导热性 金属传导热量的性能称为导热性. 一般说导电性好的材料,其导热性也好. 若某些零件在使用中需要大量吸热或散热时,则要用导热性好的材料.

thermal conductivity：导热率

例如:一、稍微改变一下合金成份的话,核能电厂里的热交换器(Heat exchanger)的导热率(Thermal conductivity)会有什麼改变?二、在铋(Bismuth)的化合物中要用多少碲(Tellurium)及硒(Selenium)才能做成最好的温差电偶发电机(Thermoelectric牛顿那时候的人已经知道热是运动的一种型式,

thermal conductivity：热传导率

因此散热片材料之热传导率(Thermal Conductivity)愈高,散热面积愈大,则其散热效率愈佳. 但无论采用何种散热方式,散热量的多寡通常和材料、散热面积、几何形状及本体与环境之温差有关. 好的导热材料可快速且均匀的导热,大散热面积增加热交换效率,
