引言有线同声传译系统难以适应比较大型的的会议,特别是会议参加者没有固定位置时更是如此。在此情况下,往往采用感应环路系统。这种系统的缺点是信号不能限制在指定传输的室内,在会议室外面有可能拾取信号,因此不易做到保密,而且邻室的环路系统可能发生互相干扰。由于这种原理所固有的有限频带所限,故环路系统的传输质量低劣,距要求相差颇远。采用光作为传输媒质的新技术与现代半
Introduction Cable simultaneous interpretation systems find it difficult to adapt to larger conferences, especially if meeting participants have no fixed place. In this case, induction loop systems are often used. The disadvantage of such a system is that the signal can not be confined to a given transmission room and it is possible to pick up the signal outside the conference room so that it is not easy to keep secrecy and the adjacent system’s ring system may interfere with each other. Due to the limited frequency band inherent in this principle, the transmission quality of the loop system is poor and quite different from the requirement. New technology and modern half using light as a transmission medium
