By using transfer function , quantitative analysis , pattern analysis and reduced analysis of driving fatigue can be finished . based on automatic control theory , driving fatigue can be analogized as two parts : inertia link and proportion differential link 采用传递函数将驾驶疲劳定量化、简约化、模式化,借用自控理论将驾驶疲劳类比为两个过程:类惯性环节的响应过程及类比例微分环节的响应过程。
However there is a bad trend in pinggu county and mentougou district , despite the fraction of green vegetation in the two districts is high . the spatial pattern analysis can help to identify the vegetation coverage spatial distribution and structure stability ( 3 ) 1994 - 1999年期间,景观整体的破碎化水平降低,异质性程度下降,景观类型的空间分布向非均衡化方向发展,但不同的植被覆盖类型表现出不同的空间分布特征。
The landscape pattern of change on the fraction of green vegetation during this period was studied using a landscape pattern analysis program fragstats by analyzing path size , number of patches , shape metrics and landscape heterogeneity metrics to show the changing feature of landscape pattern . all of these results of indices analysis emphasize that the eco - environmental system in beijing mountain area in a whole is stable and the fragmentation and heterogeneity level in the last five years is decreasing 本文在fcdmappingmodel原理和方法的基础上,利用1994年和1999年的两期landsattm数据,对北京北部山区昌平区、怀柔县、密云县、平谷县和西部山区门头沟区的植被覆盖率进行了计算,并利用fragstats软件对其景观变化过程从斑块大小、数量、形状和景观异质性等角度进行了时空格局变化的剖析。
In the present dissertation , summarized and reviewed senior ' s study of lespedeza michx . , on the basis of this , studied plants of lespedeza michx . in inner mongolia by means of polynology and cladistics taxology , discussed part of controversial species with menthod of and peroxidase isoenzyme pattern analysis 本文在回顾和总结前人对胡枝子属lespedezamichx .植物研究的基础上,对在内蒙古分布的胡枝子属植物进行了支序分类学和孢粉学研究;还对部分有争议的种类做了过氧化物酶同工酶酶谱分析。
Research on tyre noise begins with the cooperative project between automation institute of wuhan university of technology and shanghai rubber group . with the further research on tyre pattern noise , lower noise tyre pattern analysis and designing software made by us intrigues tyre industry and relative research unit more strongly , and they not only show their cooperative tendency , but make more demands on high intelligence of software 开始对轮胎噪声进行研究是因为1994年武汉工业大学自动化研究所与上海橡胶集团合作的“轮胎花纹噪声控制”项目,随着我们对轮胎花纹噪声研究的深入, “低噪声轮胎花纹分析与设计系统软件”越来越受到轮胎工业和相关研究部门的关注,他们不仅表示了合作的意愿,也对软件的高度智能化提出了新的要求。
First , based on location theories and systems model methods , the location factors were quantified by establishing the location advantage models ( including economic attraction model and spatial aggregation model ) and location feasibility models . the location advantage grades and location feasibility types were set up , according to the result of location models of daxing district . secondly , based on the landscape analysis of the 4 towns chosen form location grades system , the landscape status has been judged by landscape pattern analysis , then the relationship of location typies and landscape pattern has been analyzed 首先,依据区位理论,运用系统模型方法,将区位因素定量化建立区位优势度模刑(包括经济吸引度模型和空间聚集度模型)和区位适宜度模型,对大兴区小城镇体系的区位状况进行分析并划分区位优势度等级,分析其区位适宜状况,判断其适宜度类型;其次,对4个典型区位小城镇进行景观格局分析,判断景观格局的优势与不足,并分析区位类型与景观格局的相互关系;第三,建立格局优化模型,综合考虑经济、生态和社会三者效益,得出研究区各类景观的最优比例,并对典型城镇进行优化格局功能分区。
