By the analysis of the action characteristic of the beam-splitter,presenting a method of generating the single-photon entangled states utilizing optics beam-splitter and single-photon source. A scheme on entanglement concentration of the single-photon entanglement states is designed. In this scheme,the two single-photon partially entangled states are utilized as the quantum channel. The process of the entanglement concentration is achieved by using the 50/50 symmetric beam splitters,the photon detectors and with the help of classical information. Results show that to distill some maximally entangled states from partially entangled pure states is possible by using this method.
