摘　　要：利用曾经提出的正弦平方势解析地处理了非线性效应和偶极效应对沟道谱线宽度的影响,解释了正电子能量在5GeV附近的Si(110)面沟道辐射谱特征.The spectral properties of the planar channeling radiation of positron have been investigated by using Sine-squared Potential. At positron energy of 5 GeV a sharp line has been explained for the planar channeling radiation in Si(110 ). It is that theoretic results are compatible to the experiments.
