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。

Results analysis of data indicated a significant positive correlation among the refraction dioptres of myopia and axis length,vitreous length of eye (standardized coefficients are 0.909 and 0.803,respectively). multiple linear regression analysis of the data showed that vitreous length was the main factor to affected the formation and development of myopia diopter.

结果 眼轴长度（标准化回归系数b'j =0.909）及玻璃体腔长度（标准化回归系数b'j =0.893）均与近视屈光度呈显著正相关；用逐步回归多元线性分析法分析玻璃体腔长度、晶体厚度及前房深度各屈光要素，其中玻璃体腔长度对眼轴长度的影响最大。

In the thesis, the correlation analysis of Gray System is introduced to analysis the relationship among elevation, latitude and mean annual ground temperature .

By establishing the standard analysis graduation pattern of acoustic logging data,the distribution law that interval transit time of the key horizon declines with the increase of buried depth is obtained, and acoustic logging data are processed according to the same standard using correlation analysis, which corrects the system error caused by apparatus so as to give an assurance of acoustic logging data accuracy and its application in other aspects.

本文通过建立声波测井数据标准化分析刻度模式，给出了&标准层处的声波时差随着埋藏深度的增加而呈递减趋势&这一分布规律，并利用相关分析技术，对头台油田的声波测井资料进行统一的标准化处理，从而克服仪器刻度的不精确性造成的系统偏差，为提高声波测井资料的可靠性及在其它方面应用提供保证。

A geostatistical method was put forward to analyse the spatial variability of combined heavy metal pollution in soils based on GIS. The spatial analysis showed a combined Cu and Cd pollution occurred in the research area, Cu was mainly concentrated in surface layer, but Cd had high concentrations in 0-60cm depth of soil profile. The correlation analysis revealed that the point source pollution was dominated by the pollution let-out of the smeltery.

研究首先建立了基于GIS的地统计学采样和分析方法的步骤，然后着重分析了土壤铜镉复合污染的空间变异特征和影响因素，发现研究区土壤铜镉复合污染为点源污染类型，铜在土壤中具有明显的表聚性，而镉容易迁移，在0-60cm的土层中均形成污染，同时土壤的复合污染已经在水稻籽粒中引起污染物超过食品食用标准。
