英文摘要：

Three line profile functions are constructed by analyzing the profiles of the X-ray spectrum from laser plasmas.Applying the algorithm of least square,a multi-peaks data processing method is developed.The multi-peaks of the X-ray spectra from H-like and He-like Mg and Al plasmas are separated using the method presented,which justified its validity.The evaluation of the three profile functions is also discussed.
