1941年,美国有了固定的电视节目。像许多发明一样,电视的发明涉及了众多的人,也因此充满纠纷。有人说电视的发明人是一个从俄罗斯移民至美国的物理学家弗拉基米尔·兹沃里金,也有人说电视的发明权应该属于在马背上长大的犹他州人菲洛·法恩斯沃思。1921年,年仅15岁的法恩斯沃思已经有了利用电子来制造图象的想法。1927年,他开始研究电视技术。他在旧金山建立了一个实验室。这一年,法恩斯沃思发明了析象管,同年的一天,法恩斯沃思把一小块正方形的玻璃涂成黑色,然后在中间画了一条直线;然后,他妻子的弟弟把这个玻璃片放在法恩斯沃思发明的析象管和一盏炽热明亮的灯之间,结果,他们在接收器上清楚地看到了玻璃片上的直线,当玻璃片被
In 1941, the United States had a regular television program. Like many inventions, the invention of television involves so many people that it is full of disputes. Some people say that the inventor of the television was a physicist Vladimir Zvrikin who emigrated from Russia to the United States. Others said that the invention of television should belong to the Filipino Faith, a Utah native who grew up on horseback Ensworth. In 1921, Farnsworth, 15, had the idea of using electronics to make images. In 1927, he began to study television technology. He set up a lab in San Francisco. That same year Farnsworth invented the tube, and the same day Farnsworth painted a small square of glass black and drew a straight line in the middle; then his wife’s brother The glass was placed between Farnsworth’s tube and a hot, bright lamp, so that they clearly saw the straight line on the glass at the receiver. When the glass was
