The spatial reflected characteristic and spectral characteristic from optical material surfaces were effectively described by the BRDF (Bi-directional Reflectance DistributionFunction).
双向反射分布函数(BRDF)有效地描述了材料表面的空间反射特性和光谱特性。

In case the spectrum of incident beam is a function of triangular form, we calculated the spectraldistribution of transmission through the F-P etalon with a computer.
当入射光束频谱为三角形函数时，我们用计算机计算了透过F - P标准具以后的频谱分布。

The spectral parameters were predicted using the conditional probabilistic distributionfunction based on the pitch and were modified synchronizingly with the pitch using the sinusoidal model.
