摘要:
本文根据外球加装恒温水套的特点,求解两维球座标拉普拉斯方程,应用Legendre多项式积分,得出因外球温度不均匀所引起导热系数误差的计算式,並根据所得计算式计算了本型仪器的误差。文中介绍了水套的结构特点。论证了以圆球稳态法测试散料导热系数时,冷面加装恒温水套的优越性。
Abstract:
According to the thermal characteristics of the water-jacketed spherical heat conductivity test apparatus we solve the Laplace equation with twodimensional spherical coordinates. Using the Legendre polynomial, we obtain the equation to calculate the error in heat conductivity caused by the nonuniform temperature of the outer sphere. The structural features of the water jacket are explained. The advantge of the water-jacketed cold surface when used to measure the heat conductivity of the granulated materials by the steady heat-flow method is also discussed.
