一道英文物理题,牛人请作答!
Two rods of equal lengths and cross-sectional areas but of different materials are placed in thermal contact as shown in Figure 2.The thermal conductivity of Q
is half that of P.The outer end of P
is at 0o C and that of Q is at 100C.
What is the temperature of the interface at steady state?
A 23.88o C
B 33.33C
C 66.66o C
D 80.39o C
图就是两根棒子并排放着，一根棒子的一端很另一端有接触

你没给图，这题没办法解。先给你翻译一下：
有两根小棒，它们长度相等，交叉的面积也相等。但是它们材质不同。它们接触热源的情况如图2。Q的导热系数是P的导热系数的一半。而P的远端温度是0度而Q的远端温度是100度。问两棒交叉点的稳定平衡温度是多少？...
