摘　　要：主要结合PCR(Polymerase Chain Reaction)仪中的具体模型研究了导热问题中的非傅立叶效应,列出了在该模型中的非傅立叶传热微分方程.从理论上分析讨论了不同传热边界条件下的温度场,给出了在不同边界条件下的一维温度场的解析解,并根据这些解析解画出了主要工作面的温度响应示意图.同时讨论了在脉冲热流条件加热下时,不同热流脉冲频率对该模型的工作面的温度场响应的影响.研究了非傅立叶效应对PCR仪基座传热的影响,为PCR仪加热试验提供部分理论上的参数设计基础.Based on the non-Fourier effect on heat conductions via a specific model of PCR instrument, the non-Fourier heat transfer differential equation is provided. By theoretically analyzing the temperature field under different heat transfer boundary conditions, an analytical solution for one dimensional temperature field under different boundary conditions is presented. According to the analytical solution, the temperature response to the main working surfaces is diagramed. Meanwhile, the temperature response to the working surfaces is obtaiuned under different frequency pulse heat fluxes. In addition, the impact of non-Fourier effect on polymerase chain reaction （PCR） instrument heat transfer provides partially-theoretical base for parametric design on PCR heating devices.
