To test $R_{NLRs}~-~L_{O3}$ relation for narrow emission line regions of AGN through low redshift Type-2 AGN in SDSS
Sizes of narrow emission line regions (NLRs) of AGN could be estimated by [O~{\sc iii}] line luminosity $L_{O3}$ through the known $R_{NLRs}-L_{O3}$ empirical relations. Unfortunately, it is not convenient to test the $R_{NLRs}-L_{O3}$ empirical relations through structure properties of spatially resolved NLRs of large samples of AGN. In this manuscript, a method is proposed to test the $R_{NLRs}-L_{O3}^{\sim0.25}$ empirical relations for AGN NLRs through SDSS Type-2 AGN having few orientation …
