科研为生产服务,科学技术成果迅速转化为生产力,这是我所成立三十年坚持不渝的宗旨。1965年以来,我所确定了提高架空明线复用指数的科研课题。在漫长的岁月中,经历了一次次“政治运动”的冲击,突破了一道道技术难关,相继研制出高12路、超24路、超12路明线载波通信设备,将一对明线复用指数,从最多传输16条话路,扩充到最多开放52条话路,实现了架空明线150～530千赫全频段的复用,填补了国内空白。它以技术的可靠性和使用的广泛性,先后获得全国科学大会奖、省科技进步奖和省科技成果奖。现实与选择。通信事业的发展,取决于社会需要和发展的客观条件的统一。前者规定了通信发展的必要性,后者则取决于资金、技术等客观条件的可能性。我国幅员辽阔,人口众多,商品经济落后,发展不平衡。通信又是落后中的薄弱环节。地处西南内陆的四川省,长途通信传输主要由架空明线组成,总长度达3.7万对公里。十年改革,成效显著。尽管中同轴、光纤电缆已有了很大发展,但架空明线至今仍是我国主要的通信手段,在今后相当长的时期里仍将占有重要地位。资料表明,发达国家于60年代已向电缆载波发展,而发展中国家则主
Scientific research serves production and the achievements in science and technology are rapidly transformed into productive forces. This is the unshaken objective of the thirty years since my founding. Since 1965, I have identified research projects to increase the overhead line multiplexing index. In the long years, it has undergone a series of “political movements” and broke through the technical difficulties in one round of joint development. In succession, it has developed the high-12-lane, ultra-24-lane and 12-lane clear line carrier communication equipment, , From the transmission of up to 16 sessions, expanded to up to 52 sessions, to achieve overhead overhead line 150 ~ 530 kHz full range of multiplexing, to fill the gaps. It is the reliability of technology and the use of the extensive, has won the National Science Conference Award, Provincial Science and Technology Progress Award and Provincial Science and Technology Achievement Award. Reality and choice. The development of communications depends on the unification of social conditions and the objective conditions for development. The former stipulates the necessity of communication development and the latter depends on the possibility of objective conditions such as capital and technology. My country has a vast territory, a large population, an outdated commodity economy and an uneven development. Communication is a weak link behind. Located in the southwest of Sichuan Province, long-distance communication transmission is mainly composed of overhead light lines, a total length of 37000 pairs of kilometers. Ten years of reform have achieved remarkable results. Although the coaxial cable and optical fiber cable have been greatly developed, the overhead cable is still the main means of communication in our country and will continue to occupy an important position for a considerable period of time in the future. Data show that developed countries in the 1960s has been to develop a cable carrier, while developing countries, the Lord
