Ancient Greek society built tension between friendship theory and reality, relying on Life characteristics and cultural prosperity contending. They integrated the common brotherhood love, friendship, family, relationships between God and person, citizenship love into their lives through its unique lifestyle, and began a process of mutual shaping. It is intense and harmonious of sex and love,this is the most significant feature of their friendship view. There are a number of reasons of culture, politics and life for the Transition of Ancient Greek view of friendship. Ancient Greek view of friendship has been echoed in history, and has important implications to China's cultural and moral construction.展开更多

The situation, in which absorbers are located at different depths with respect to the limited-view scanning trajectory, is called depth imaging and is investigated in this paper. The results show that limited-view scanning causes the reconstructed intensity of deep absorbers to be weaker than that of shallow ones and that deep absorbers will be invisible if the scanning range is too small. The concept of effective scanning angle is proposed to analyse that phenomenon. We find that an effective scanning angle can well predict the relationship between scanning angle and the intensity ratio of absorbers. In addition, limited-view scanning is employed to improve image quality.展开更多
