Abstract	Basing on evaluated atomic structure and dynamical parameters, we calculated the emission spectrum for the ICF plasmas in the conditions of local thermodynamic equilibrium and non-local thermodynamic equilibrium, and study the properties that the spectrum changes with plasmas temperature and density. It was found that the intensity ratios between the principal resonance lines and between the satellite and the principal resonance line change sensitively with the plasma temperature, while the spectral profiles are sensitive to the plasma density. These properties are used to analyze a few shots of implosion experiments performed at the China Academy of Engineering Physics. Thus the plasma temperatures and densities are derived, and we can judge whether the doped argon in the implosion capsule mixes with sulfur doped in the inner surface of the implosion capsule. Furthermore, by analyzing and modeling the photon-emission spectrum, it is verified that some spectrum come from the high-temperature and high-density plasma of gold hohlraum, which may result from the plasma compressing and squeezing among hotspots when multi-beam lasers irradiate on the wall of golden hohlraum. This high-energy-density zone is known as a "Cross" structure.
