在实验研究的基础上,分析了应用锎源实验结果预估空间轨道单粒子翻转率的可行性.以静态存储器的锎源单粒子翻转截面为例,分3种情况预估了该器件在地球同步轨道上的单粒子翻转率.结果表明,若器件的锎源单粒子翻转截面小于10~(-10) cm~2/bit,在地球同步轨道上的单粒子翻转率则应小于10~(-8) d~(-1)·bit~(-1).%Feasibility of prediction for single event upset rate based on ~(252)Cf experimental results in space orbits was analyzed. Taking static random access memory as an example, its single event upset (SEU) rates in geostationary orbit were predicted under three circumstances based on its ~(252)Cf SEU cross sections. The result shows that SEU rate in geostationary orbit should be smaller than 10~(-8) d~(-1)· bit~(-1), if ~(252)Cf SEU cross section is smaller than 10~(-10) cm~2/bit.
