The second, prefect newsboy model with two times ordering and solve this model. The third, research on newsboy model with reduce price and get it optimum solution.

2阐述并完善了二次订购情况下的报童模型，通过分析可以看出采用二次定购的策略可以提高销售商的平均收入。

This paper studies a supply chain model in which a single supplier sells a single product to a single retailer facing the newsvendor problem. Both the supplier and the retailer can exert costly efforts to increase demand.

为了研究分布决策对供需链性能的影响，对单销售商、单制造商、单一产品、一次采购、需求为随机变量且供应商制造商均可以通过促销努力扩大需求的报童模型进行了讨论，提出了一种形式化的合同策略，多种简单合同形式均可以纳入其中。

Firstly,3D point clouds produced by 3D laser scanner are converted into polygon mesh.Then,normal vectors and areas of every polygon mesh are computed and some candidate regions are obtained using region dilation strategy.Finally,the 3D laser scanning data is segmented into regions of similar orientation after the elimination of the insignificant regions.

首先将三维扫描表面数据转化为三维网格模型；然后利用同一区域中相邻网格具有相似法线方向这一性质，使用区域膨胀策略生成若干获选表面区域；最后通过去除候选区域中的噪声区域得到最终表面区域分割结果。
