%X The parameters and property of Level symmetrical Ebert-Fastie spectrograph was studied.Based on the light-path diagram of Level symmetrical Ebert-Fastie spectrograph,it was deduced for the calculating equations of included angle between incident light and diffracted light,angle of incidence,angle of diffraction,measurable spectrum grade and measurable range of wavelength,by geometry methods.Based on theoretical resolution’s calculating formulas,the equations of interaction between resolution and structure parameters was deduced in view of slit width.By deriving the equations,improving resolution’s methods were come into being.The example of calculating revolution shows that the practical revolution in view of slit width is 83% of the theoretical resolution in which slit is infinitely slender.
