具有 120°偏转角的偏转线圈优化设计

Optimum Design of the Deflection Coils with 120° Deflection Angle

研究了屏的位置与偏转角之间的关系以及彩色质量因子Ｑｋ与偏转角之间的关系．对１２０°偏转角的偏转线圈进行了优化设计，给出了优化结果．

The relationship between the deflection angle and the position of the screen and the relationship between the colour quality and the deflection angle are investigated. The optimisation result of the deflection coils with 120° deflection angle is obtained. A good convergent result is given.
