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。

The six channel instantaneous optical pyrometer is used to measure the thermal radiation of the light source at six bands from visible to near infrared spectrum.
六通道瞬态光学高温计是在可见光和近红外光谱范围内，把光源的热辐射取出六个波段进行测量。
