With a correlation analysis , the long - term practice of regional development provides a great evident to prove that the dominate factor of land use change of yrb , out of most experts ' expection , is the wide spread industrialization in the rural area rather than concentrated itself in the urban area 跨部门的相关分析结果表明，在长达半个世纪的经济发展过程，决定长江干流土地资源投入状态变化的主导因素是农村地区工业化，而不是城市化发展本身。
The outlook of modern education is dominant element among them . it guides the modernization of another fields such as educational contents , educational management , teacher troops building and educational institutions , etc , and influences modernization of chinese to realize finally 其中，现代教育观是现代教育的主导因素，它引导教育其它领域诸如教育内容、教育管理、教师队伍建设、教育设施等方面的现代化，最终影响着中国人的现代化的实现。
According to the contrast between different maps and the dynamical conditions , the area of bohe lagoon had reduced by 45 . 3 % from 1932 to 2000 and human activities in the coastal zone , such as inning , sand dredging and aquiculture , have brought great effects on the coastal system , which has accelerated the barrier erosion and lagoon evolvement 通过对比分析， 1932 ~ 2000年，博贺?湖面积减少45 . 3 % ，人类活动已成为影响该区海岸演变的主导因素；滩涂围垦、海岸采沙与水产养殖等人类活动加剧了沙坝海岸的侵蚀后退，且使得?湖面积迅速减少，不断淤浅萎缩，大大加快了海岸体系的演化进程。
The collapse mainly occurs in the low - water years or during the beginning of the dry season and rain season in a year . the formation and developing scales of the collapse are affected by many factors , such as karst caves , sola and water , etc . however , the taking of the underground water which causes the hydrodynamic conditions changed and the water level highly descended is a leading factor for the karst collapse . the mechanism of karst collapse is discussed based on long - term monitoring results of groundwater level and geological environment 塌陷的产生与发展规模受溶洞、土层和水等多种因素的综合影响,但过量开采地下水导致地下水动力条件急剧改变或水位大幅度下降是造成塌陷形成的主导因素;进一步讨论了泰安市岩溶塌陷的形成机理,在此基础之上对泰安市岩溶塌陷的监测预报及对土地资源管理利用的影响进行了研究,并根据当地的防治实践,提出了岩溶塌陷防治的对策建议。
Based on the original data of tm in 1988 , 1992 and 1998 , then after some processing and analysis , the author have the thematic data of land - use by interpretation . on the basis of them , the author made the analysis of land - use for this area based on the spacial analysis of gis and the method of comparison between result of land - use classification as follows : the method of aggregating analysis , the analysis of urbanization , the analysis of the transformation rate of cultivated land , the analysis of the driving force of land - use change and the sustainable use of land . the conclusions may be demonstrated below : the cultivated land decreases with the patchs fragment ; road spreads radialy surround second - ring road ; the urban land expands quickly toward southwest along the major roads and be concentrative . rural land and industry increse rapidly with dispersing ; 0thers change slowly . the major driving forces of land - use change in this area are the rapid expansion of urban and rapid growth of population , foreign investment and the development of tertiary industry which was based upon the real estate . according the trendency of land - use change , the author consider that we must insist on the way of the sustainable use of land based on protecting the cultivated land 在此基础上，应用分类结果比较法，在gis各种空间分析功能(几何量算、统计分析、叠加分析及缓冲区分析)的支持下，对该区土地利用变化进行了如下分析：土地利用综合分析、城市化进程分析、耕地转化率分析、土地利用变化因素分析及土地的可持续利用分析。结果表明：该区土地利用变化主要表现为耕地大量减少，斑块破碎化；交通用地沿二环线呈放射状向四周扩展；城镇用地沿交通干线向西南方向扩张迅速，用地趋于集中；农村居民点和工矿业用地增加，用地趋于分散；其它用地变化较慢。这一用地变化的主导因素是城镇用地扩展快、人口增长迅速、外资的大量投入及以房地产为主的第三产业的快速发展。
Then the restricted factors inflecting xi ' an urban spatial structure ' s expansion are analyzed . the author also studies dominant and relevant factors influencing xi ' an urban spatial structure ' s expansion . after the research of the expanding direction and leading factors of xi ' an spatial structure , the author insists that urban spatial expansion has the character of diversity 论文从多个层面研究西安城市空间结构的组成要素及其演化特征，分析西安城市空间结构扩展的制约因素，对空间结构演替的主导因素和相关因素进行探讨，研究西安城市空间结构扩展的方向和导向，分析城市空间结构扩展的异质性特征。
It is indicated that the relaxation of elastic energy stored during the forward martensitic transformation is responsible for the expansion of transformation hysteresis , which is in good agreement with experimental results associated with the hysteresis enlargement by deformation of niti , niti - based and cualni shape memory alloys 结果表明，塑性变形产生的位错以及变形的第二相颗粒对逆马氏体相变温度的提高具有一定作用，但塑性变形导致应变能释放才是形变提高形状记忆合金相变滞后的主导因素。
By compounding caco3 with pp , the effect of caco3 content , diameter and shape on the crystallization , dispersion morphology and properties of pp / caco3 composites was investigated . the results showed that addition of caco3 into pp decreased the apparent crystal size in perpendicular direction to the ( 110 ) , ( 040 ) and ( 130 ) crystallographic planes of ppa crystal , and with similar uniform dispersion of caco3 , the dominant factor influencing toughness is the diameter of caco3 particles , but not the decrease of pp crystal size . the toughening effectiveness of nano caco3 is obviously better than that of micron caco3 将caco _ 3与pp进行填充复合，研究了caco _ 3含量、粒径及形状对体系的结晶，分散形态及性能的影响，发现碳酸钙的加入使聚丙烯晶型垂直于( 110 ) 、 ( 040 )和( 130 )晶面的表观晶体尺寸减小，揭示了在分散均匀的情况下，影响材料韧性的主导因素不是晶粒尺寸的减小，而是碳酸钙的粒径，纳米张玲：弹性体及无机刚性粒子增韧增强聚丙烯复合材料的研究碳酸钙的增韧效果明显优于微米碳酸钙。
This method is different from tradition method of building index system in : those tradition methods only compute the relation among indexes while mine compute the relation of every factor to ouput . at the end of this paper , it proves this method effective by a practical example , its conclusion can be testified trule on economics and suitable to the fact 影响大的因素就应该是主导因素，体现在互信息中就是该因素与该系统的互信息更大。论文在最后用一个实际例子证实了这种方法的有效性，所得出的结论也都有合理的经济解释，符合实际情况。
Through studying it is shown that in chagan sag , the geothermal gradients in the center are higher than those around the sag margin and major factors influencing the characteristics of temperature field distribution are the property of geotectogenesis and the differences in tectonic portion , lithology and underground water behaviour ; there are three types of mudstone compaction , i . e . normal compaction , undercompacition and overcomepaction ; there are two pressure systems in sandstone reservoirs , i . e . normal pressure and negative pressure systems and the strata ' s being uplifted and denuded is the key factor leading to the formation of the negative pressure system in reservoir ; and the distinctive temperature - pressure field characteristics in the sag are possessed of important petroleum geological significance in hydrocarbon source maturity , hydrocarbon generation , widening on oil and gas exploration domain and selecting exploration targets , etc 研究表明，查干凹陷中心的地温梯度高于凹陷边缘，大地构造性质及所处构造部位、岩性与地下水活动的差异是影响凹陷地温场分布特徵的主要因素；泥岩压实存在正常压实、欠压实和过压实三种类型，砂岩储层段压力类型可分为正常和负压两个系统，地层抬升剥蚀是导致储层负压系统形成的主导因素；凹陷独特的温压场特徵对烃源岩成熟、油气生成、油气勘探领域的扩大及勘探方向的选择等具有重要的油气地质意义。
