The purpose is to inspect the grade differences on time of mental addition and mental subtraction of pupils from three grades as well as grades differences of arithmetic time and integration time. The results show that mental arithmetic time of pupils from Grade 2, 4 and 6 decreases with the increase of grades.In the non-carry mental addition of 1-digit number and multi-digit number, menta...

研究结果表明，2、4、6 年级小学生口算时间随年级的增高而减少；在一位数加多位数不进位加法口算中，口算时间差异主要源于运算时间差异和整合时间差异；在一位数加多位数进位加法口算中，口算时间差异源于运算时间差异；在多位数减一位数不借位减法口算中，运算时间年级差异不显著，而整合时间存在显著的年级差异；在多位数减一位数借位减法口算中，口算时间的年级差异主要表现为运算时间的差异，而整合时间差异不显著。

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。
