本文通过对一种完全理想的平面环绕声系统进行逐级近似，得到了一系列新的其性能逐级提高的平面环绕声系统．文中首先分析了完全理想系统的重发信号及系统在各级近似下的重发特性，给出了相应的独立传输信号和重发方程，探讨了各级近似重发间的兼容性问题。分析了系统重发时输出通路的简化条件，探讨了信号的检拾，记录，传输等问题和将系统付诸应用的可能性。文中对上述多通路平面环绕声系统（包括４－３－Ｎ系统）进行了声像定位实验，探讨了环绕声重发中声像定位与独立传输信号，重发扬声器数目的关系，得到了同理论分析相一致的结果，同时也为实际应用提供了实验基础。
In this paper, a completely ideal planar surround system is approximated step by step, and a series of new planar surround systems with improved performance are obtained. In this paper, we first analyze the retransmission signal of the perfect ideal system and the retransmission characteristics of the system at all levels of approximation. The corresponding independent transmission signals and retransmission equations are given, and the compatibility of the retransmission at each level is discussed. The simplified conditions of the output path during system retransmission are analyzed. The problems of signal pick-up, recording and transmission and the possibility of applying the system are discussed. In this paper, the multi-channel planar surround sound system (including 4-3-N system) conducted a sound image localization experiment to explore the relationship between the sound image localization and independent transmission of signals in the surround sound re-transmission, the number of retransmission speakers, has been the same Theoretical analysis of the same results, but also for practical application provides the experimental basis.
