ABSTRACT:Based on the characteristics of quartz lamp radiation heater, the influence of following factors on experiment performance is was analyzed, such as sensor weak signal transmit, reactive power compensation, intelligent control, profile modeling heater design and open loop experiment way. Combined with the implementation of transient thermal environment experiment implementation process, the corresponding corrective actions based on the above constraint thermal experiment im-plementation aspects wereare given, in order to improve the effectiveness of transient thermal experiment of experiment system.%结合石英灯辐射式加热器的特性，从传感器弱信号传输、无功补偿、智能控制、仿形加热器、开环试验技术等角度出发，分析了对型号瞬态热试验性能的影响。结合瞬态热试验的实施，给出了上述几个角度制约热试验实施的改进措施，以期提高试验系统瞬态热试验的有效性。
