摘　　要：综述双极器件和双极线性电路在低剂量率辐射环境下的增强损伤,它可引起系统的早期失效。分析了引起低剂量率失效的物理机制,它与MOS器件电离辐射的损伤机制完全不同。为了缩短模拟试验时间和提高效/费比,研究了几种加速模拟试验方法,并对处于低剂量率下系统的加固保证也提出了一些看法。The enhanced damage was summarized for bipolar devices and bipolar linear circuits in the radiation environment of low dose rate. It could cause the early failure of systems. The physical mechanism of producing failure of low dose rate was analyzed. This is totally different from the damage mechanism of MOS devices caused by ionizing radiation. In order to shorten the time of simulating test and to raise the ratio of effectiveness/spending, several test methods of accelerating simulation were researched. Some points of view were put forward on system hardness assurance at low dose rate.
