    • A color cathode ray tube apparatus is provided with an electron gun assembly. In the electron gun assembly, three electron beams, which are emitted from cathodes of an in-line arrangement, are accelerated and converged onto a phosphor screen by an electron lens system of the electron gun assembly. The electron lens system is constituted by a plurality of grid electrodes and includes individual electron lenses and a common electron lens. Each of the individual electron lenses has first and second lens powers in horizontal and vertical planes, respectively. Each of the electron beams is diverged in the horizontal plane and converged in the vertical plane by the corresponding individual electron lens due to the first and second lens powers. The common electron lens has third and forth lens powers in the horizontal and vertical planes, respectively. The electron beams from the individual electron lenses are converged in the horizontal plane by the common electron lens due to the third lens power and each of the electron beams diverged by the common electron lens due to the fourth lens power.
    • 彩色阴极射线管装置设有电子枪组件。 在电子枪组件中,从串联排列的阴极发射的三束电子束通过电子枪组件的电子透镜系统被加速并会聚到荧光屏上。 电子透镜系统由多个栅格电极构成,并且包括单个电子透镜和公共电子透镜。 每个单独的电子透镜分别在水平和垂直平面中具有第一和第二透镜功率。 每个电子束在水平面上发散,并由于第一和第二透镜光焦度而被相应的单个电子透镜会聚在垂直平面中。 普通电子透镜在水平和垂直平面上分别具有第三和第三透镜光焦度。 各个电子透镜的电子束由于第三透镜光焦度而由公共电子透镜在水平面中会聚,并且由于第四透镜光焦度而由公共电子透镜发散的每个电子束。
