There are two features used in first method : area distribution of 3d model surface and latitude orientation average radius distribution . quadratic form distance function has been applied to calculate the similarity of two feature vectors and two passes are needed to search database in first method 第一种检索技术使用了两个特征：面积分布和纬度方向平均半径分布，在相似度计算使用了二次方程式距离计算公式，数据库检索采用了分步检索方法。
The sar s largest - ever all - season theme park will occupy a total indoor space of 70 , 000 sq ft and an outdoor area of 35 , 000 sq ft , and will be designed by jumpin gym u . s . a . under an innovative theme featuring " edu - tainment " and " interactive entertainment " elements targeting teenagers and families 全港最大型全天候主题公园的室内及室外面积分别占地7万平方尺及3万5千平方尺，以青少年及家庭为目标顾客对象，由美国冒险乐园以崭新的教育娱乐及互动游戏为主题设计及兴建。
Then figure out the wind load in term of the load criterion and the wind tunnel test results separately . by comparing with the two results , we can draw a conclusion that the values which generated by the load criterion are bigger than these ones generated by the other . in order to calculate and design in the worst situation , the paper select the bigger basic wind stress and then turn the area - load into liner - load to receive the displacement of the nodes and the internal force of the cells generated by the static wind load 由此，得出用于作业棚结构设计的数据，进而按建筑荷载规范和风洞试验数据分别计算出风荷载标准值以及基本风压，通过对两种静力风荷载计算的结果进行比较，可以看出，按规范计算风荷载的结果在结构的整体计算中偏于保守。按照最不利情况计算的设计准则，本论文选用较大的基本风压值按受力面积分配的方法把面荷载转化为线荷载代入midas运算程序中，求得该结构在该静力风荷载作用下的节点最值位移。
