The sine-squared potential is introduced in this paper, and the instantaneousintensity 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。

When using the instantaneousintensity ratio method, the event of first arrival curve becomes more smooth, and abnormal points have greatly reduced, thus the accuracy of picking is greatly enhanced.
