英文摘要: Low-temperature specific heat capacities of foam glass ( Type 150P) have been measured from 79 to 395K by a precision automated adiabatic calorimeter. Thermal conductivities of the glass foams have been determined from 243 to 395K with a. at steady-state heat-flow meter. Experimental results have shown that both the specific heat capacities and thermal conductivities of the 150P foam glass increased with temperature. Experimentally measured specific heat capacities have been fitted by a polynomial equation from 79 to 395 K: C-p/J(.)g(-1) (.) K-1 = 0.6889+ 0.3332x- 0.0578x(2)+ 0.0987x(3)+ 0.0521x(4)- 0.0330x(5)-0.0629x(6), where x = (T/K - 273)/158. Experimental thermal conductivities as a function of temperature ( T) have been fitted by another polynomial equation from 243 to 395 lambda/W (.) m(-1) (.) K-1 = 0.14433 + 0.00129T - 2.834 x 10(-6)T(2) + 2.18 x 10(-9)T(3). In addition, thermal diffusivities (a) of the form glass sample were calculated from the specific heat capacities and thermal conductivities and have been fitted by a polynomial equation as a function of temperature (T): a/m(2) (.) s(-1) = -1.68285 + 0.01833T - 5.84891 x 10(-5)T(2) + 8.11942 x 10(-8)T(3) - 4.24975 x 10(-11)T(4).
