摘　　要：在用平面变换技术实现密集信号分选时￣［１～３］，具有“多义性”──即有时会出现与某种信号的特征曲线形状相似的“伪特征曲线”．文中就平面变换技术多义性的原理进行了分析，论证了何种情况下会产生伪特征曲线．在此基础上，提出了识别伪特征曲线的方法和分选伪特征曲线的方案．多义性的分析使平面变换技术更完善和实用．In separating concentrated signals,the technique of plane transformation[1～3]has multi-meaning. Sometimes the 'Fake Characteristic Curved(FCC)on the plane which is similar to the true characteristic curve may be observed in plane transformation. This paper analyses the principle of multi-meaning, demonstrates the cause of the FCC. Meanwhile, and presents some methods of distinguishing and separating the FCC. The analyses of multi-meaning make the plane transformation more perfect and practical.
