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。

As in different area, adjusting net radiation convert coefficient only can solve the daily evapotranspiration calculation problem from the instantaneous evapotranspiration value.

对于不同地区只要调整净辐射折算系数便可解决由蒸散发瞬时值求算全天值的困难。
