The sine-squared potential is introduced in this paper,and the instantaneous intensity and the average intensity of the channeling radiation are obtained analytically.
引入正弦平方势,并在抛物线近似下解析地处理了沟道辐射的瞬时辐射强度和平均辐射强度。
By comparing the transitional radiation with the channeling radiation, one finds that the background of the channeling radiation is enhanced in the long wave region by the transitional radiation, and the transitional radiation of the superlattice is strong, because the superlattice is constituted with multi-layer films which are alternately grown up with two materials with different dielect.
讨论了非沟道粒子与晶体的相互作用及其渡越辐射,并将渡越辐射同沟道辐射进行了比较,结果表明,渡越辐射对沟道辐射的贡献主要是在长波区域使沟道辐射的本底增强;由于超晶格是由两种不同介电性能的材料交替生长而成的多层薄膜结构,它的渡越辐射比较强。
The properties of the radiation spectrum are discussed, indicating that it is possible to take channeling radiation as a new γ-Laser.
引入正弦平方势,将面沟道粒子的运动方程化为无阻尼、无受迫的Duffing方程,并用Jacobian椭圆函数和椭圆积分解析地给出了系统的解和粒子运动周期,讨论了正电子面沟道辐射谱的一般特征,指出了利用沟道辐射作为激光的可能性。

指出了非线性效应、多普勒效应、晶格热振动、电子多重散射和偶极效应等对沟道辐射谱线宽度的影响;强调了辐射反作用对谱线宽度的影响是不可避免的。
The quasichanneling radiation is described by using a sinesquare potential, and point out that the quasichanneling radiation is related directly to the rotation periodic solution; The properties of the phase plane and the possible model approaching to chaos for the system is analyzed.
在经典力学框架内,描述了带电粒子自发辐射的频谱分布与辐射频率;利用正弦平方势讨论了带电粒子准沟道辐射,指出了准沟道辐射与系统的旋转周期解相联系;分析了系统的相平面特征和准沟道粒子进入混沌的可能途径。
