Unit 30 Something about Telephone…………………533
电话点滴
现在，电话已经成为世界上最普通的音频通讯工具，今天的电话较之当时贝尔发明的简陋装置，是无以伦比的精巧和有效，而且，今天使用电话的方式也是贝尔当年不可能预见的……
When imaginative scientists first suggested the possibility that one person could speak directly to another over a long distance, few people took them seriously. Among the few who did was a Scots-born(苏格兰出生的) American named Alexander Graham Bell(亚历山大?格拉海姆?贝尔，美国发明家), who was one of the first to develop a telephone in 1876. Now the most common means of voice communication in the world, the telephone of today, is infinitely¹ more sophisticated and effective than the crude instrument developed by Bell, and it is being used in ways he could not possibly have foreseen.
One area that is rapidly expanded is communications service “on the move”. Because America is such a highly mobile society—a society on wheels—telephones in cars and trucks are becoming as essential as those in homes and offices. Industry officials have predicted that mobile communications service will soon be more competitive in many respects than the service provided by telephones that do not move.
Another area rapidly developing is overseas telephone service. In 1927, when overseas telephone service was inaugurated(开创) with a radio telephone call between New York and London, the occasion was heralded(宣布) as “thrilling”. Today, many telephone users regard international calls as routine, and overseas service, thanks largely to undersea cables(海底电缆) and communications satellites, has undergone extraordinary improvement. Transmission has been made clearer, charges have been greatly reduced and dependability has been improved. Overseas telephone service has now been extended to nearly 350 countries and areas throughout the world.
The introduction of direct distance dialing in 1951was one of the most significant developments in the effort to improve long-distance service. Direct distance dialing is not only fast and convenient for the caller, it has also enabled telephone companies to handle the extraordinary growth of telephone use that has occurred since the 1950s. between 1950 and 1973 the number of telephone in the United States tripled, with the addition of 90 million telephones. For the Bell Telephone System(贝尔电话公司) alone, long-distance calls in the same period have increased from 1.4 billion to 8.5 billion, and indications have shown that long-distance calls will continue to increase significantly in the years ahead. In 1972, 77 percent of the 8.5 billion long-distance calls were dialed by the customer.
Another very significant development in telephone use is in the area of data communications. Here is an example of how medical data are being transmitted. In a small town in the western part of the United States about 300 people gathered in the local school to undergo tests for lung diseases. The procedures followed marked a major advance in detecting diseases by providing almost instantaneous computer diagnosis² over long-distance lines. First, technicians at the school used touch-tone telephones(按键式电话) to send vital statistics on the person being tested to the computer, which was located in a hospital 60 miles away. The individual then exhaled³ into a spirometer(肺活量计测仪), which measures volume and rate of air exhalation(呼气), and these measurements were automatically transmitted to the computer. The computer instantly calculated the results and within two seconds relayed them back to the testing center. Normally, it takes hours or even weeks to evaluate spirometer measurements. By utilizing⁴ a computer and data communications, however, the time lag is reduced to seconds. Moreover, people in a remote community are put within arm’s length of the most up-to-date medical facilities available.
For many people the most exciting development in recent years is picturephone service(可视电话业务). Picturephone services, which will become available commercially at the beginning of this century, is being used by large business corporation; but it will no doubt spread from the office to the home. It is already clear that the next best thing in telephone service is going to be picturephone call.
Possibly the most significant research now being conducted is in the use of the laser beam in telephone communications. This wonderful light, first produced by scientists in 1960, can beam continuously and with extraordinary intensity⁵. Instead of using light to see by, telephone researchers are thinking of way to use light to communicate by. In other words, they are thinking of using light as radio waves to transmit telephone calls, television programs and data messages from one point to another, with the expansion of picturephone service and high-speed data communications between computers, present message-carrying capacities may soon become inadequate⁶. If it turns out to be technically⁷ and economically sound, the laser might prove to be a major breakthrough in telephone communications.
Current research in telephone communications is so extensive and changes are coming about so rapidly that no one can predict with accuracy what the telephone of tomorrow will look like. But there is at least one prediction that can be made with assurance: there will be more and more telephones in the future, and the will be much better than present ones.

对于许多人来说，近几年来最令人兴奋的进展是可视电话的产生。可视电话将在本世纪初投入商业性使用，当前正为一些大型企业所采用。无疑，它将从办公室扩展到家庭。已经很清楚，可视电话即将成为电话业务中的下一个最好的业务。
目前进行的最重大的研究可能是激光在电话通讯方面的应用。这种于1960年被科学家首先创造出来的神奇光线能够以极高的亮度连续发射。电话研究人员不是研究利用光来看东西的技术，而是研究利用光进行通讯的技术。换句话说，他们正在想办法用光取代无线电波，把电话、电视节目和数据信息由一个地点输送到另一个地点。随着可视电话业务的扩展以及计算机之间高速数据通讯的发展，目前的信息传递容量可能很快就难以满足需求。如果证明激光在技术上可靠、在经济上可行，那么在电话通讯中，激光可能成为一项重大的突破。
目前在电话通讯方面的研究，内容如此之广，变化如此之快，没有人能准确地预言未来的电话将会是什么样子。但至少可以有一个很有把握的预言：未来，电话的数量将日益增多，其性能也将比现在的电话更为优异
