英文摘要	以传统的大平板热保护法测量绝热材料为理论基础,提出基于埋入式热流计法快速测量真空绝热板导热系数的方案。通过有限元分析软件AnSyS仿真分析,证明了该测量原理的可行性。通过硬件电路设计和相关测量方法,实现了真空绝热板导热系数的快速测量。实验结果表明,该检测方案具有操作简便、检测速度快、测量精度高、成本低廉等优点,可广泛应用于工业测量领域。; A novel technique was developed to rapidly and accurately measure the thermal conductivity of vacuum insulation panel( VIP).The newly-developed device,mainly consisting of a wirelessly powered and controlled circuit of a resistive-heater and a thermistor embedded in VIP,was based on evaluation theory of thermal insulation materials of conventional large flat thermal protection plate and structure of the embedded-type heat-flow sensor.The time evolution of the temperature field closely around the thermistor after resistive heating for different time intervals was empirically approximated,physically modeled,and numerically simulated in finite element method with software ASNSYS,to prove its feasibility.The test results revealed quite a few technical strengths of the new technique,including low cost,easy operation,high accuracy,and rapid measurement of thermal conductivity of VIPs.; 福建省重大科技计划项目(2010H6025)
