在此全固体化设计的时代,仍然有一种类型的管子处在大力发展之中:正在世界范围内制造的彩色电视阴极射线管的年产量约二千四百万只。1974年在整个国际市场中约占有二十亿美元——几乎等于全世界的集成电路销售额——这是当今最好出售的管子。 世界上十余家彩色管制造商,在最近几年内已提供了宽范围的图象尺寸大小、偏转角、荫罩、材料和快加热的样管。在显象管设计师中间,并不是以同等的热情来对待每一项革新的。 In this era of fully solidified design, there is still one type of pipe under development: the annual production of color television cathode ray tubes being manufactured worldwide is about 24 million. In 1974 it accounted for about two billion U.S. dollars in the international market - almost equal to the worldwide sales of integrated circuits - the best pipe to sell today. More than a dozen color tube manufacturers in the world have provided a wide range of image size, deflection angles, shadow masks, materials and fast heating tubes in recent years. In the CRT designer, not with equal enthusiasm for every innovation.
