Differential relation between optic parameter and lattice parameter in HLS storage ring

In this paper, the differential relation between optic parameter and lattice parameter in electron storage ring of HLS is presented; the lattice parameter at downriver is evaluated and analyzed when the optic parameter at upriver is changed. Using the expression the lattice parameters is calculated when the Wiggle is inserted, satisfying the need of the improment of NSRL (National Synchrotron Radiation Lab.). Considering this relation, the lattice is designed renewedly in order to reduce the b function where the Wiggler was inserted.
