英文摘要	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.
