摘　　要：对于固体火箭发动机的推力和压强测试系统,用AD-1精密数据放大器代替SF-72数据放大器,仪器精度由0.1%提高到0.02%,改善抗干扰性能,提高稳定性,解决了数据采集,即与A/D的匹配问题,同时可节省供桥电源,经济性好,可推广应用.As AD-1 precision data amplifier has been used in the measuring systems for the thrust and the pressure of solid rocket motors instead of SF-72 data amplifier,it is found that the measurement accuracy rises up to 0.02% from 0. 1 %, the anti-interference ability and the stability are improved, and the match with A/D in data sampling is also solved.Meanwhile, it makes a power supply for bridge eliminated for better economization. So the application is worth being extended.
