摘要：A shadow mask for a cathode ray tube is formed with a curved surface such thata radius of curvature corresponding to a perpendicular axis which passes through thecenter of the shadow mask decreases monotonely along the perpendicular axis from thecenter of the shadow mask and a radius of curvature corresponding to a parallel axis

which passes through the center of the shadow mask decreases monotonely along theparallel axis from the center of the shadow mask. The curved surface satisfies thefollowing condition, [0.1RV+0.9RV, 0.9RV+0.1RV]⊂[RH, RH]. RVand RVrespectivelyrepresent the minimum and the maximum value of the minimum radius of curvaturecorresponding to the perpendicular axis, and RHand RHrespectively represent theminimum and the maximum value of the minimum radius of curvature corresponding tothe parallel axis.
