Popis: This paper presents data on the continuous spectrum of CH/sub 2/O plasma for quantum energies of 1-1000 eV as well as its thermodynamic functions. The partial composition of the multicomponent plasma was calculated from a Sach-Eckert system of equations, taking the weak nonideality into account by the Debye equation, supplemented by the conditions of quasineutrality and maintaining the relationship between the number of particles of the various elements. Photoionization of the excited states having a principal quantum number greater than that for the ground state of the outer electron was calculated by the more approximate quantum defect method. To calculate the remaining highly excited states, integral relationships were used. The authors calculated the absorption coefficients averaged over the 16 spectral intervals which are necessary for making calculations in a multigroup approximation. It is shown that for calculations of the phenomena in a polyformaldehyde plasma having parameters lying principaly within the limits of the ranges indicated, a linear interpolation in logarithmic coordinates and the extrapolation of the data are recommended.
