Scientific paper

Radial galactic abundance gradients of some chemical elements in 125
planetary nebulae are investigated. The abundance gradients of nitrogen
and oxygen are found for low-mass planetary nebulae. The dependence of
the electron temperature of planetary nebulae on galactocentric distance
and on the abundance in them of oxygen and carbon is discussed.
