monochromatic emissivity meaning in Chinese

单色发射率
单色放射率

In the study , sd2000 spectrometer is applied to obtain radiation spectrum of flame within wavelength 480 - lloonm , from which flame temperature and monochromatic emissivity are derived by newton raphson non - linear method and levenberg - marquart modeling method . the flame monochromatic emissivity is translated in form of f ( / l ) and a ( a ) respectively
在该方法中，采用sd2000型光纤光谱仪测量火焰在可见光( 480 - 1100nm )波长范围内的火焰的辐射光谱，结合newton - raphson非线性迭代算法和levenberg - marquardt最优化算法，得到火焰温度和单色辐射率变化规律。
