英文摘要：

Calculations of energy levels and radiative rates for Kα transitions among the lowest 40 fine-structure levels were introduced in Be-like ArⅩⅤ. The wavelengths, oscillator strengths, radiative rates and lifetimes for all possible Kα transitions have been calculated using the multi-configuration Dirac-Fock method. The accuracy of the results is determined through extensive comparisons with existing laboratory measurements and theoretical results. These results can be used to analysis the previous experimental results and guide the design of the future experiments.
