光辐射计 meaning in Chinese

photoradiometer

The approach is that we first calibrate the filter radiometer with cryogenic radiometer and measurement equipment of relative spectral responsivity and then calculate the absolute spectral responsivity . because the drift in blackbody temperature directly influnces measurement accuracy , so we adopt a feedback system to stabilize blackbody temperature through controlling the current of blackbody that improves measurement accuracy greatly
该方法首先要用低温辐射计及相对光谱响应度测量装置对滤光辐射计进行标定，经计算可得到滤光辐射计的绝对光谱响应度；由于黑体温度的漂移直接影响到测量精度，我们采用反馈系统通过控制黑体的加热电流，来稳定黑体温度。
The measurement system is made up of optical system , comparison system , control system and cooling system in the course of the temperature measurement of high temperature blackbody , we use filter radiometer that is a new approach to measure radiation temperature . the approach was adopted by ptb , npl and vniiofo in 1997 when they made international comparisions of spectral irradiance
在测量高温黑体温度的过程中，使用了新型的辐射测温法，滤光辐射计测量方法，该方法在1997年光谱辐照度国际比对时被ptb 、 npl 、 vn ofo等国家所采用，并得到一致认可。
