The results are shown as below.1 Tectono-thermal evolution: The history of the Songliao basin is divides into four stages, high-temperature doming and extension, high-temperature rifting, low-temperature depression, and low-temperature shrinkage. Numerical simulation of mechanical process shows that the basin appeared in the early- to late- Jurassic as a result of rapid low-angle subduction of the Pacific plate towards the northwest, of movement of the Siberian block towards the southeast, of many other influences such as internal thermal stress in the mantle, gravitational force, stress of phase transition, etc. Both the Pacific plate and the Siberian block slowed down in the early Cretaceous, and almost stopped in the middle Cretaceous with the rapid decrease of abnormal heat in the mantle below.

盆地构造热演化力源机制数值模拟研究表明：早、中侏罗世至晚侏罗世晚期，盆地演化主要是太平洋块体向北西方向以低角度快速俯冲和西伯利亚块体向东南俯冲共同作用的结果，同时也与地幔内部热力、重力、相变力以及地球自转及公转速度变化效应和上覆块体绝对运动的作用有关；早白垩世早期至早白垩世中期，来自东部太平洋块体俯冲作用的减弱，而这一时期影响盆地演化的主要力源是地幔内部热力、重力、相变力以及地球自转及公转速度变化效应和来自西伯利亚块体俯冲作用；进入早白垩世晚期至晚白垩世早期，由于双重俯冲带中西侧俯冲作用带基本停止活动，而本区地幔热能的快速衰减则控制盆地的构造热演化；晚白垩世晚期以后，太平洋块体活动加强和地幔热运动是影响盆地演化的主要动力。

The research method is combining historic happening with scientific research.This paper is composed of seven chapters. The preface explains briefly the reason of choosing this topic and its significance, as well as the existent research situation in the academic circle.The first chapter presents the subjective and objective historical condition of the formation and development of his view about population quality in four aspects.The second chapter gives a full play to its evolution: it gestates and germinates before the failure of the revolution in 1911, takes shape and develops in the period of Base Area. The following period after the founding of People's Republic of China is its mature time. This view also experiences twisty developments in China's exploring period of socialism.The third part focuses on its major connotations, including Mao's narration on the connotation of Population quality, his analysis of contradiction between population quality and Chinese revolution and construction and of their significance, and the way to enhance Chinese population quality.The fourth chapter makes analyses of philosophical support of Mao's view from three "adherences": adherence to basic principle of seeking truth from facts;adherence to the common acknowledged fact that the people is the main part of history;adherence to the dialectical relation between being and consciousness.

At last, the development of capitalization operation of intangible assets in the world, in our country is explained. After I give my points on the difficulties of capitalization operation of intangible assets in our country, the solutions are concluded.
