| 英文摘要 | We use previous high-quality experimental spectra to test the accuracy of atomic data and the validity of the collisional-radiative (CR) model used in this paper. The synthetic spectrum with electron temperature log T-e (K) = 6.745 and electron density n(e) = 6.0 x 10(13) cm(-3), which almost reproduces the experimental spectra, is presented. Nearly all the features of the experimental spectra were identified. The results of the CR modelling for the emission spectra of calcium plasmas all agree well with the measured spectral line intensities within the experimental error for most of the lines. Furthermore, we make the electron temperature diagnostic through the synthetic spectrum and population fractions of every ionization state as a function of charge state at different electron temperatures, as well as the electron density diagnostic through the intensity ratios of two lines of Be-like calcium and three lines of C-like calcium. A good agreement between the calculated values and the measured ones is found. |
