| 摘 要： | 通过有限元法及正文变换，从“集总参数化”模型出发，本文研究了以正弦激励为代表的热动态激励信号及其温升响应，并通过计算机的具体计算和热激励实验，验证了理论分析的正确性。文中还讨论了热系统特征值与热激励频率对响应滞后的影响。

| Abstract: | Based on lumped parameter model of FEM, this paper analyzes the temperature response of a linear thermal system to a dynamic heat excitation of sine signal. The analytical results togatherwith numerical solution agree with experimental measurements quite well. In the paper, the facter such as heat excitation frequency, thermal system characteristic which effect the delay angle of temperature response are also discussed. |

| Keywords: | heat excitation sine signal response delay angle |
