分析了影响SSC注入能量的因素和SSC注入系统适应能量变化的能力，计算了在理论等时场下SSC注入系统对3种典型离子O8+,Xe22+和Ar15+的能量可接收范围，找出了加速较轻的重离子时束流损失较大的部分原因.
The SSC injection system and the factors which influence theinjecting beam energy were described and the capability of the SSC injection system for accepting the mismatching injecting beam energy was calculated. For most cases, small difference exists between the values of actual injecting beam energy and the theoretical requirements. The capability of accepting three typical particals: O8+, Xe22+ and Ar15+ were calculated for the SSC injection stystem with small variation of the injection beam energy. The results show that for light particles with high energy, because of its small turn separation, the beam easily hitts the injection components, which leads to beam intensity loss. The high Dee voltage is required to increase the turn separation. For heavier particles, the SSC injection system can accept them in a large energy scale.
