摘　　要：为了满足大学工程热力学课程的实验教学要求,针对传统实验装置因加热温差范围过大而导致实验结果不准确的问题,设计开发了一套新型气体定压比热容测定实验系统.设计的新型气体定压比热容测定实验系统通过结合预热段、保温、两次测量算法改进等方式,使实验结果更加准确可靠,真实地反映了实验原理,具有较高的精度,完全满足本科研究性实验教学要求.In order to meet the experimental teaching requirements of the Engineering Thermodynamics course in the university, a new experimental system for measuring specific heat capacity of gas at constant pressure is designed and developed to solve the problem of inaccurate experimental results caused by the large range of heating temperature difference in traditional experimental devices. The new experimental system for measuring specific heat capacity of gas at constant pressure is designed by combining preheating section, heat preservation and two measurement algorithm improvements, which makes the experimental results more accurate and reliable. It truly reflects the experimental principle and has high accuracy, and fully meets the requirements of undergraduate research experiment teaching.
