First mostly contraposing hull deck structure it goes along FEA analysis, discuss the different influence degree of calculational results between the different simplifications of the mathematical model, thereinto mostly analyse five different simplifications of the deck model; Second contraposing hold section and hull deck structure it goes along FEA analysis together, discuss the different influence degree of calculational results between the different elements style, gridding number and gridding density, thereinto mostly analyse the difference between adopting 8 node shell element and 4 node shell element, nondense gridding and thick gridding, and numerous gridding number and few gridding number, In the end mostly contraposing hold section structure it goes along FEA analysis, discuss the different influence degree of calculational results between the different boundary conditions, thereinto mostly analyse the difference between adopting CCS boundary conditions and LR boundary conditions.

首先主要针对船体甲板结构进行分析研究，讨论结构简化不同对有限元计算结果的影响程度，其中主要研究分析了五种不同甲板结构简化模型；紧接着针对舱段与甲板结构一起进行分析研究，讨论单元类型，网格数量与密度的不同对有限元计算结果的影响程度，其中主要研究分析了分别采用8节点板壳单元与4节点板壳单元的不同，以及分别采用疏的网格与密的网格，多的网格数量与少的网格数量的计算结果的差异。最后主要针对舱段模型进行分析研究，讨论不同的边界条件对有限元计算结果的影响程度，其中主要研究分析了分别采用CCS舱段边界条件与LR舱段边界条件进行有限元计算而带来的结果上的差异。本文第二部分为港工建筑物中的大直径薄壁圆筒结构的有限元比较分析。在研究大圆筒的有限元比较分析中，主要讨论用不同的网格密度与数量来划分网格引起的差异。其中用了网格密，数量多与网格疏，数量少两种模型进行大圆筒结构的有限元分析对比

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
