In this work we have discussed the fundamental equations of eight radiation charts. The interrelations of transmission function with pressure and temperature were discussed. We not only investigated the problems of heat radiation which are affected by carbon dioxide and water vapour in spectral overlapping region, but also analysed the errors of carbon dioxide radiation of some charts. Finally, the comparison of various radiation charts for atmospheric emissivity has been made.According to this study, it is...

In this work we have discussed the fundamental equations of eight radiation charts. The interrelations of transmission function with pressure and temperature were discussed. We not only investigated the problems of heat radiation which are affected by carbon dioxide and water vapour in spectral overlapping region, but also analysed the errors of carbon dioxide radiation of some charts. Finally, the comparison of various radiation charts for atmospheric emissivity has been made.According to this study, it is possible to find out the reason for the differences in the calculation results with these charts and to estimate, to a certain extent, the advantages and drawbacks of these charts.

Crystalline field energy levels of central ion and lingands for complex ions CuX4 --(X = Cl, Br) were given. By considering the crystalline field effect, and by using the modified Wolfsberg-Helmholz 's molecular orbital approximation, the energies for the ground state and some of the excited states of these complex ions were calculated. The calculation results are in agreement with the features of the observed lingand field transition bands and electron-transfer spectra.
