Secondly, this dissertation analyses the action characters of soccer robot, designs kinds of actions in allusion to switchover of attack and defend, puts forward theory of action selection and rules of action selection in order to realize part cooperation which combines court subarea and switchover of attack and defend when soccer robot is under special state thirdly, after considering the characters of obstacles in the robot soccer, we have founded the collision module, to the current questions of obstacle - escaping arithmetic, we put forward the new obstacle - escaping strategy based on the speed vector information which is able to dope out the potential obstacles in the moving path and count out the suitable velocity to escape obstacles by the aid of the geometry transform of obstacle velocity vector the grid implementation arithmetic of path - searching tree is set forth for the convenience the result of simulating competition showed that this way is suitable to the mobile obstacle escaping

Considering that the characteristics of our country ' s highway tunnels are always of long spans, tabular and of various geometry, by means of thorough analysis of the different problems existed in the design of support structures of the tunnels at present, this paper pays special attention to the two key problems, optimization method of form selection of structural section of the tunnel as well as the stability and bearing capacity of the support structures, in the design of the long and large tunnel on high - class highway, introduces the simplified complex - form optimum method in the structure optimization theory, discusses the optimum design model of lining section of highway tunnel with satisfying demands in building clearance, ventilation and load conditions, puts forward an optimization method of form selection of three different kinds of lining sectional forms ( i. e. single - center circle, three - center tabular circle and three - center sharp circle ), establishes a complete set of systematic optimum design the ory and method of long and large tunnel on high - class highway, develops the corresponding computer software used on the planned xuefeng mountain highway tunnel on shaoyang to huaihua expressway in hunan province for optimization of form selections of the structural sections, and obtains a series of relatively reasonable structural design parameters
本文針對我國公路隧道多為大跨度、扁平、幾何形狀呈多樣化的特點，通過深入分析目前隧道支護結構設計中存在的各種問題，抓住高等級公路長大隧道設計中隧道結構斷面的優化選型及隧道支護結構的穩定性與承載能力兩個核心問題，引入結構優化理論中的簡易復合形優化方法，深入探討了滿足建築限界、通風條件、受力狀態約束等條件下公路隧道襯砌斷面優化設計模型，提出了三種襯砌斷面形狀（單心圓、坦三心圓和尖三心圓）的優化選型方法，建立起一套完善的高等級公路長大隧道的系統優化設計理論與方法，並開發出相應的計算機程序，用於擬建的上海至瑞麗國道主幹線湖南省邵陽至懷化高速公路雪峰山長大高速公路隧道的結構斷面優化選型，得出了一系列較為合理的支護結構設計參數。 -
