First , this paper analyses the present situation of weinan region ' s tourism space development ; and then , uses the theory of " point - axis " spatial system to analyze the developing course and developing tendency of weinan tourism space . at last , on the base of the study conclusion , the author sets forth the developing conception of weinan sustainable tourism space . meantime , the supporting system is discussed 首先，文章深入分析渭南区域旅游空间的发展现状；然后，运用“点?轴”空间系统结构理论对渭南区域旅游空间的发展过程与发展趋势进行动态分析；最后，根据分析研究的结果，针对渭南区域旅游空间的现实状况和发展需求，阐述了笔者基于渭南区域旅游可持续空间的发展思路，提出区域旅游可持续空间建构的具体措施，同时，讨论了区域旅游可持续空间发展支持体系的建立。
At first , the dynamic mathematic model is created in the light of the known dimensions and structure . then base on the mathematic model , dynamic analysis of the system is studied by drawing the open - loop bode diagram closed - loop bode diagram and step response curve using the analysis and calculating function of matlab . the influence factor on frequency character steady and performance of the system is also analyzed 首先，根据已确定的尺寸参数和结构需要，计算并建立起系统的动态数学模型，然后在已知系统数学模型的基础上，利用matlab语言强大的分析计算功能，对系统进行动态分析，通过画出系统的开环bode图、闭环bode图及系统的阶跃响应曲线，分析了系统的频率特性、稳定性及系统性能的影响因素。
Evolution mechanism of logistic equation is studied , and is used in a kind of cobweb model . the stability and the characters are studied with the change of parameters . finally the parameters " regions in which the economic system reaches the stability and the chaos are determined 第五章：逻辑斯蒂方程在蛛网模型分析中的应用本章研究了逻辑斯蒂方程的演化机制，并将它应用在一类蛛网模型的研究中，对模型进行动态分析和稳定性分析，研究了各种参数条件下的性态，确定了经济系统达到稳定状态的参数范围及进入混沌状态的参数范围。
First , on the base of investigating geleshan geologic environments , the author carefully analyzes them , studies their water storage structure , discusses the relationship of underground water dynamic changes and tunnel drainage by desiccation ; secondly , the author makes the dynamic analysis , regression analysis , routine hydrochemistry analysis , isotope analysis , so draws to guan - yin gorge anticlire east and west slot ' s karst developing features , alternated conditions underground water and supplying drain ways ; thirdly , by stating the fissuring ' s surveying data , the author calculates the seeping tensor 作者在进行歌乐山地质环境调查的基础上，仔细分析了大量观测资料，研究其储水构造，掌握地下水动态变化与隧道施工涌水的关系，及补给受降雨的影响情况。对隧道周围的地下水进行动态分析、回归分析、常规水化学分析以及同位素分析，得出观音峡背斜东西翼槽谷的岩溶发育特征，及地下水的循环交替条件、补给排泄途径；统计分析裂隙测量数据，计算渗透张量。
Directed by the theory of the earth systemic science , applying new technologies ( including remote sensing , geographic information system , global position system ) and a proper mathematical model , and combined with multiple subjects ( geology , geography , meteorology , hydrology , human culture , et al ) , the dissertation makes a dynamic analysis and a comprehensive evaluating research on the desertification of the capital and its periphery , and unveils the evolving mechanism of the desertification 论文以地球系统科学理论为指导，运用遥感( rs ) 、地理信息系统( gis ) 、卫星定位系统( gps )即3s集成技术，多学科(地质、地理、水文气象、信息、社会人文等)相结合，并选用适当的数学模型，对首都及邻区土地沙漠化现状及发展趋势进行动态分析与综合评价研究，初步揭示了首都及邻区土地沙漠化演化机理。
The simulation results show that using the bond graph could not only reflect the dynamic characteristic in effect , but also having the following advantages . 1 ) based on the commonness of the multi - power field , using the uniform mathematic analyze way , programming the software from beginning , holding the key technology 通过结果的演示，证明了使用键合图理论可以对混合动力电动汽车进行动态分析，并且具有以下优点： 1 )从多能源领域的共性出发，用统一的数学分析手段，进行底层的软件开发，掌握关键技术。
