It is deemed here that the legitimacy of power under the peculiar conditions of ancient societies was destined by the other world outside of human beings', such as religion, theology, etc. In ancient societies, the power and governance were justified by means of God's will, divine regulations, exceptional human power and exterior transcendentalism.
本文认为,在古代社会特有的历史条件下,古代社会中权力的合法性由宗教、神学等外在于人的彼岸世界所支撑,古代社会的权力,往往要借助神的意志或是神法规则,借助超人的力量和外在的先验秩序来赋予自身统治的合法性。

Based on the prior information obtained by qualitative inversion, the two stages inversion method was put forward. That is, the first stage is that distinguishing the high-quality element and non- high-quality element, and determining the initial iteration value of element sound velocity reasonably. The second stage is that treating differentially the constraint weights of the high-quality element and non- high-quality element, and then quantitatively inversing the final sound velocity distribution. The results of two concrete specimens indicate that the two stages inversion method can inhibit artifacts effectively and has better defect identification effect than normal one stage inversion.
