中文摘要：

利用基于多组态Dirac-Fock方程的程序包GRASPVU,考虑电子关联作用,详细计算了类Mg离子3s^2-3s3p跃迁（Z=20～24）的能级、波长、振子强度和能级寿命.研究表明,考虑了电子关联作用之后,所得的理论计算结果与实验值以及其它理论值符合得很好,同时对于分析已有的实验结果和指导拟开展的实验也很有意义.

英文摘要：

Using the multi-configuration Dirac-Fock method and the corresponding package GRASPVU,as well as considering the electron-core correlation,the energy levels,wavelengths,oscillator strengths and life times for mag-nesium-like ions of the transition of 3s2-3s3p are calculated.The results with electron-core correlation are found to be in a good agreement with the experimental results and the available theoretical results.These results can be used to analyses the previous experimental results and guide the design of the future experiments.
