不久前,苏联莫斯科的一所大学制造出了由一个很小的半导体仪器代替电子管的叫“卫星——2”牌的电視机。这种电視机的特点是:使用性能很好,半导体仪器比电子管寿命要长得多,可以使用几万小时;耗电量少,一台只要有一个十二伏特的蓄电池就够用;体质輕,携带方便,每台只有七公斤重。“卫星——2”装有200×150厘米的螢光屏,灵敏度和普通电视机一样。据設計人員說,这种沒有电子管的电視机有很大的发展前途,
Not long ago, a university in Moscow, the Soviet Union, made television sets called “satellite-2” with a small semiconductor device instead of a tube. This TV is characterized by: the use of good performance, semiconductor equipment, the life of the tube is much longer than the tube, you can use tens of thousands of hours; less power consumption, as long as a 12 volt battery is enough; Light, easy to carry, each weighing only seven kilograms. “Satellite - 2” equipped with 200 × 150 cm fluorescent screen, the same sensitivity and ordinary television. According to designers, this TV without a tube has a great future,
