查询词典 third dimension

The innovation in the paper: First, it combines the higher education research and the population economic structure research together, searches the best meet-point of higher education research among different subjects, broadens the field and vision of cross research between higher education and closed subject from the horizontal dimension. Second, it discusses the basic relationship between higher education development and the components of population economic structure theoretically at the micro-level; moreover, it analyzes the correlation modes, existing problems between them in Henan Province, and provides the corresponding countermeasures. Third, it takes in the methods of quantitative analysis and qualitative analysis as a body..

论文的创新之处在于：一、把高等教育研究和人口经济结构研究相结合，在不同学科间寻找高等教育研究的最佳切合点，从横向层面拓宽了高等教育与相邻学科间进行交叉研究的领域和视野；二、从人口经济结构的微观层面，在理论上探讨了高等教育发展与人口经济结构诸组成部分间的基本关系，并以河南省为研究对象，细化分析了二者间的关联模式和存在的问题，提出了相应对策；三、融定量分析与定性分析于一体。

The results reveal that under the conditions of the third-class sites in the Southern Fujian mountain areas,the suitable planting density is 1250～1798 trees/hm 2 for building eucalyptus short-cycle industrial raw material forests; and adopting the present density to conduct afforestation may culture the best-selling dimension lumber with higher growth and may obtain better economic benefits.

This paper summarizes the research job of predecessors, full text is divided in four part:The first part introduces the develop history and present conditions of MCRE;In the second part, the concept of average Markov process is introduced. Moreover we investigate the relations for Markov processes, martingales, stationary processes and average Markov process systematically.The third part summarizes the model that constructs the MCRE by p-m chains and skew product Markov chains by p-m chains, also we discuss the relations among the basic gunctions of the probability character for MCREIn the fourth part, we discuss the dimension of GW-tree and the canonical branching chain in random environment, furthermore we summarize the exact formulas of mathematical expectation and variance of branching chain in random environment.
