摘要： 本文将位错对沟道粒子的作用等效于晶体弯曲,考查了常曲率晶体的退道效应。引入正弦平方势,把粒子运动方程化为具有δ-力矩的摆方程,并用能量法分析了系统的相平面特征,导出了退道系数。

Abstract: This paper adopts the effect of the dislocation of channeling particle, which simulates as the bend crystal, to consider dechanneling effect of bend with constant curvature and introduce sine-squared potential so as to reduce the motion equation into pendulum equation with the δ-moment. Besides the characteristics of phase plane was analyzed by energy method, the dechanneling coefficient was derived.
