In the stable conduction of a multi-layer cylindrical wall, the heat transfer rates through each layer are Q1, Q2, and Q3 (in watts), the heat fluxes through each layer are q1, q2, and q3 (in W/m2), the temperature drops across each layer are Δt1, Δt2, and Δt3, and the thermal resistances of each layer are R1, R2, and R3; assuming that these parameters are equal in all layers. Which of the following statements is correct? A.Q1=Q2=Q3 ； B. R1=R2=R3 ； C.q1=q2=q3 ； D. Δt1=Δt2=Δt3.
