The main research is below : ( 1 ) the influence to intensity and rigid with corner angle ( 60, 75 and 90 degree ) of crack and the board axes ( 2 ) do a fem stress / strain and crack growth simulation analysis when the corner angle of crack and the board axes is 60 degree ( 3 ) do a intensity resume analysis for the structure which is repaired with a titanium patch in a mechanical way when the corner angle of crack and the board axes is 60 degree through simulation analysis for three failure criterion, we have : ( 1 ) in 60, damage extend quickly with damage analysis in hashin criterion; it is slower for analysis in maximum stress or hashin-rotem criterion . ( 2 ) in special term ( physical condition incision, shape or maximum load ) the compression strength of the stiffened plate will decline 45 % ~ 50 % under compression loads 通过采用三个不同损伤判据的数值仿真模拟,得到如下结论:(1)在60时,用hashin判据进行的损伤分析,损伤扩展较快;最大应力及hashin-rotem判据进行的损伤分析,损伤扩展基本相当,且较慢;(2)在所给加筋板的物理条件、切口大小及形状、最大载荷等一定的条件下,该加筋板在压缩载荷作用下,其压缩强度下降了4550;(3)在本文提及到的机械连接修理方法以及载荷条件下,修理后的结构强度恢复能够满足战时要求。
It puts emphasis on planning urban green space and surveying green belts " function from the angle of regional space; paying attention to reserving natural remains, regularly contributing green patch in city by means of constructing the whole urban green space system connected with green corridor 强调从区域空间视角规划城市绿地,审视环城绿带的作用。重视保留自然遗留地,将绿地斑块均匀布局于城市,用绿色廊道加以联系构筑完整的城市绿地系统的规划手法,并建议景观生态学原理应用于城市绿地系统规划。
In a word, the landscape heterogeneity exist in different scales and so the green space has a landscape pattern which is much favor to the stability of ecosystem . 4 ) : its green patch's figuration index and fractal index are correlating with its tree diversity index and the shape design of different styles patches in this park is adapted to the planning of its trees diversity . 5 ) : its gr een patch's figuration index and fractal index are not correlating with its plant community dissimilarity index and so the design of the landscape heterogeneity in the interal patch is not suitable for its pattern 花港观鱼公园绿地景观格局参数中斑块形状系数与分维数都与各斑块树种多样性指数表现出相关性,满足了生态系统空间相关性的要求。花港观鱼不同类型绿地斑块形状与树种多样性配合设计是成功的。花港观鱼绿地不同类型斑块内部群落相异性指数与其对应的斑块格局参数没有呈现相关性,这个绿地生态系统的植物群落差异性属性不具有空间相关性,花港观鱼绿地斑块内部异质性设计与其景观格局不匹配。
Taking landuse-dat files as data sources, this paper discusses the features, data structure, and generating methods of topological relationships of between in landuse database generalization, and puts emphasis on the methods for preserving consistency of topological relationships of patches in the process of landuse database generalization 摘要以landuse-dat文件为例,论述了土地利用地图综合中图斑多边形拓扑关系的特点、数据结构定义及生成方法,阐述了土地数据库综合过程中图斑拓扑关系一致性的维护方法。
Then, pattern synthesis for sparse array antenna using genetic algorithms is researched . at last, we researched on conformal patch on the surface of cylinder and the effect of conformal antenna platform on the radiations of patches in different positions . how to get a good feeding for conformal array antenna by genetic algorithms is presented in the end 文中介绍了遗传算法在综合低副瓣阵列中的应用;采用遗传算法给阵列天线的方向图赋形,其结果优于同种条件下用woodward法得到的结果;同时,考察了遗传算法的稳定性;分析讨论了遗传算法在综合稀疏相控阵方向图综合中的应用。
