中文摘要：

对合肥光源注入系统进行分析，介绍了几组合肥光源中等发射度lattice．根据注入分析，将粒子的水平工作点取在半整数共振线附近，模式的发射度在60nm·rad左右，这样可以在兼顾较好的线性及非线性性质下得到较低的发射度．

英文摘要：

A method of injection analysis of small electron storage ring was introduced, and several medium emittance lattices were proposed. By analyzing the injection, the working point of the lattice was selected at the vicinity of half integer resonance lines, and the emittance was around 60 nm ·rad. The linear and nonlinear properties can be satisfied for injection and storage.
