摘　　要：以环绕声分离式前方三声道拾音制式为模板,通过计算与数据分析对其两个子定位区域声像还原情况进行考察。证实了在该类拾音方式中,两个子定位区域有效拾音范围的部分重叠导致其声像定位不准确。针对此问题引入Williams的"平滑连接"理论,并确定将以其为主题进行后续的相关研究。The sound image accuracy of the two regions based on front three separated channels in surround recording is discussed. It came to a conclusion that sound image is not fully effective due to the overlap between two regions. So the theory of ＂critical linking＂ by Williams is brought up in order to solve the problem,which is also our next step topic.

关 键 词：分离拾音方式 双子定位区域 拾音范围重叠 Williams理论
