众所周知,广播是用电声形式发送信息的大众传播工具。声音是它赖以存在的唯一形式(声音包括言语和音响)。而广播中大量的有声作品都需要通过播音这一环去完成,播音是做为广播系统内的一个要素子系统而存在着的。那么作为一个要素子系统,它现存的结构与功能状况又如何呢?它是否有利于发挥广播的整体优势呢?本文试图用系统方法,遵循整体性、历时性和最优化的原则 It is well-known that broadcasting is a mass communication tool that sends messages in the form of electroacoustic sound. Sound is the only form it exists (sounds include speech and sound). The broadcast of a large number of audio works need to complete this broadcast through the ring, broadcast as a system of elements of the radio system exists. So, as an element subsystem, what about its existing structure and function? Is it conducive to the overall advantage of broadcasting? This article attempts to use the systematic approach to follow the principle of integrity, duration and optimization
