    • A method for thermal characterization of a portion of first material of elongate shape on which there is arranged a portion of a second, electrically conductive material of elongate shape, the method including: a) determining characteristic of the portion of second material, b) applying an electric current of angular frequency between ends of the portion of the second material, and measuring the angular frequency harmonic of the electric voltage between these ends for different values of angular frequency, c) calculating coefficient of thermal conductivity of the portion of first material from the values of the harmonic and of the determined characteristic, a width of the portion of the first material being between about 0.9 and 1.1 times the width of the portion of second material, the portion of first material being surrounded by thermal insulation.
    • 一种用于热表征细长形状的第一材料的一部分的方法,其中布置有细长形状的第二导电材料的一部分,所述方法包括:a)确定第二材料的部分的特性,b)施加 在第二材料的部分的端部之间的角频率的电流,并且针对不同的角频率值来测量这些端部之间的电压的角频率谐波,c)计算第一材料部分的导热系数 所述谐波和所确定的特性的值,所述第一材料的所述部分的宽度在所述第二材料的所述部分的宽度的约0.9和1.1倍之间,所述第一材料的所述部分被热绝缘包围。
