讨论了大型运载火箭动力系统非线性稳态参数（系统平衡点参数）对于内外扰动因素的敏感性。考虑的内外扰动因素包括：系统结构参数与组件性能参数变化、推进剂性能参数变化、推进剂供应系统入口压力变化和环境温度变化，并得出了有指导意义的结果。

The sensitivities of the nonlinear static characteristics of large launch vehicle propul sion system to the various interferential effects,such as the variation of environment temperature,parts performance and structure parameters are calculated and discussed.
