    Abstract
  • To study the effect of opacity on solar plasma X-rays in solar coronal region, using the basic theory of photon escape factor in spectral analysis, the effect of opacity on intensity ratio of solar OⅧ 1.897nm and 1.601nm spectral lines is analyzed. Under optically thick conditions, theory of the effect of photon escape factor on the intensity ratio of the solar spectral lines is discussed. In the calculation, the optically depth of OⅧ spectral lines is discussed, and finally the effective emission thickness of OⅧ ion in solar plasma is estimated. Results show that under optically thick conditions, the opacity has great effect on solar OⅧ spectral line, and the effective emission thickness of OⅧ ion is greater than that in other solar ultraviolet spectral line. This is important for plasma diagnose in solar plasma emission layer.
