After reviewing wavelet theory , pyramid wavelet decomposition was introduced to texture representation , we discussed the problem of optimal window size for texture feature extraction method ; the problem of local statistical feature value refinement has been studied , and a refinement method has been given which can decrease the boundary effect in calculating the feature value 在叙述小波分析理论的基础上，把金字塔小波分解引入到纹理表示中来，讨论了提取纹理特征值时选取窗口大小的问题；研究了局部统计特征值的改进问题，给出了一种对所提取的纹理特征值的改进算法，一定程度上克服了计算纹理特征时的边界效应。
Taking the evolution equation of a kerr resonator and cgle for example , we discuss pattern formation with system boundary effects . spatial modulated instability induced pattern formation in shg is discuss also . detail of linear stability analysis , numerical simulations and their consistencies are presented 首次讨论了前一模型系统的边界效应对斑图形成的影响，给出了详细的线性稳定性分析结果和数值实验结果，证明边界对斑图的形成具有重要的影响和选择机制。
But due to the difficulties of the theoretical calculation and the limitation of the technique of image display , only some two - dimensional graphs of electromagnetic field of a planar set of point charges or symmetrically and uniformly charged bodies , which ignores the boundary effect , are introduced in the present electromagnetics teaching materials , which brings much incovenience for the acquaintance of the electrostatic field 然而,由于受理论计算和图象显示技术等因素的限制,目前的电磁学教材中,通常只能给出平面分布的点电荷系或具有较强对称性、忽略边界效应的带电体的电力线和等势线的二维平面图,这给静电场分布的感性认识带来了一定不便。
On the basis of frequent field - studies , in the light of the basic theories of ecological design , it tells the benefits and necessity of ecological design for city squares , and demonstrates the basic aims ( aim of function , aim of image , aim of environment ) ; according to the weather and vegetation characteristics of subtropical zone , it tells the cardinal principles ( humality , sustainable development , characteristics distinguishing , integral harmony , public participation ) for the design ; with regard to the architecture enclosing , the space organizing , the boundary effects of city squares , and their size and color , this dissertation also analyzes the space and environment of city squares , and especially discusses the ideas of how to decide the size of a square regarding the problem of building big city squares blindly ; and summarizes the key points of ecological plan and design for the component factors of the space and environment of city squares , and the problem of greening of squares is paid much attention 在多次实地考察的基础上，本文从生态设计的基本理论出发，指出了城市广场生态设计的意义及必要性，明确了设汁的基本目标(功能目标、形象目标、环境目标) ；结合亚热带区域的地理气候与植被特征，提出了亚热带区域城市广场生态设计的基本原则(人性化、可持续发展、突出特色、整体协调、公众参与) ；分别从尺度、色彩、与周边建筑的围合、空间组织、边界效应及内部交通等方面对广场的空间环境进行了分析，其中针对当今我国广场建设中“盲目求大”的现象，重点分析了如何把握广场的尺度问题；总结了广场的绿化、地面铺装、建筑小品、水体等空间环境构成要素的生态设计要点，其中着重讨论了当今广场建设中颇为严重的绿化问题。
To settle the phonomenon of seasons , we design the boudary full of sunlight at the side of groud - floor space ; to make the peoples in the uptown have the feeling of safety and ascription , we optimize the quality of the enrance space ; we design the solid sight carport to improve the quality of physical environment , such as lighting airiness and sight 边界效应的存在使住宅架空层在边缘地带具有更多的活力，我们通过构造措施在这里形成边界阳光区，从而改善架空层在使用中的季节性现象；为了提高社区的人文品质，我们优化住宅的入户空间，使居民具有更强的归属感和安全感；通过立体景观车库的设计，改善车库内的采光、通风以及景观条件，从而改善地下车库的物理环境质量。
A rich social activity provides the basis for the existence and the guarantee for the of urban recreation - square . based on theory of environment psychology , start with user ' s behavior and psychological need , get acress investigation of several representative urben recreation - squrae in chengdu , this thesis analysis on deferent users , users " behavior , factors which inspiring square ' s energy , ubiquitous problems etc . and summarizes the usage condition of urben recreation - square . with all of these , corresponding advice and measures for urben recreation - square are put forward in two aspacts , the whole construct and concretely design 本文主要以环境行为学和和环境心理学为理论基础，以城市游憩广场的使用者的行为特点和心理需求为出发点，以成都市为研究的地域范围，通过详细调查具有代表性和典型性的几个广场，对其使用人群、使用者行为活动特征等几个方面进行研究，总结城市游憩广场普遍存在的问题，并提出区位效应、宜人的气候、边界效应、小群生态、兴趣中心效应等是影响广场使用的主要因素。
