摘　　要：二代红外焦平面探测器组件微型杜瓦中的金属引线是跨接在探测器芯片以及陶瓷引线环之间,其作用是作为介质为探测器芯片提供数字以及模拟信号,并将探测器组件的输出信号导出。本文介绍了二代焦平面探测器组件的杜瓦结构,并对金属引线在低温77K时的物理特性进行了分析,从理论上对金属引线可流过的最大电流进行计算,并通过试验进行验证。The metal lead wire in dewar i i between the ROICand the ceramic lead circle, and it can provide digitalsignal and analog signal for the ROIC, and export the output signal of the ROIC. The asembly is introduced, and the physical characteristics of the metal lead wire are analyzed at 77 K. The maimum cur-rent that can flow through the metal lead wire is calculated theoretically ,and is venfied by experinent.
