The greater the extinction coefficient of the initiator, the lower the concentration with initiator exponent being zero power.
If the weather condition of the atmosphere changes a little in short time, we can consider that the extinction coefficient has no change.
Moreover, the output pulse duration can be adjusted within specified range, the extinction coefficient reaches 50000, and the transmittivity is higher than 90%.
After dividing a flame section into M× N grids, the temperature and radiative extinction coefficient distribution were obtained by iterating the discrete equations and the Algebraic Reconstruction technique( ART) simultaneously.
The curves of refraction index and extinction coefficient with different wavelength and the thickness of films were obtained from transmission spectrum.
The extinction coefficient for diffuse and direct radiation is given by crop canopy architecture and solar position.
