The graphical model for point pattern matching in JT algorithm is proved sensitive to the outliers in template point-set recently. To efficiently solve the problem, this paper sampled on the point in the separator, and derived the relationship between the times of the sampling and the ratio of the outliers.

为解决概率图模型匹配算法对模板点集中的外点敏感的问题，对隔离子进行了采样，并推导出采样次数和模板点集中的外点比例关系，以保证隔离子中的点能最大概率地为内点，使得推理算法中每个点的信息能得到传递。

Fourth, the clan in West and East Han dynasties kept self-governing and self-protecting function, such as memorial ceremony for ancestors, relieving inside clan, labor cooperation, mutual financial aid and etc, as well as the function of controlling local government.

族人由于离不开土地这一生产资料，对庄园的依赖性变得相当之强，而在大宗族庄园中，土地这一资料是集中而非分散的，土地的经营却又是分散而非集中的。

Under the current Land Resources Bureau in Beijing and the Beijing Municipal Construction Committee, and Albert, the network of intermediaries, such as Hua High Rice Company, in 2005 the sale of part of certain properties of tetracyclic and pentacyclic more in between the City project less greenbelt project, and the new disk is relatively concentrated geographical perspective, mainly in the Chaoyang, Tongzhou and Fengtai.

根据目前的国土资源局在北京，北京市建设委员会和阿尔贝，网络的中介机构，如华高莱斯公司，在2005年出售某些性能的四环和五环更多城市之间的项目较少绿地项目，新盘相对集中的地域角度来看，主要集中在朝阳，通州和丰台。

Results of pulling test reveal that the nominal strength ratio of corroded hot-rolled steel bar over uncorroded one is approximately equal to the ratio of maximum residual sectional area over the uncorroded one.And the rupture extension ratio of corroded hot-rolled steel bar is exponentially decreased with the maximum sectional loss ratio.The effect of stress concentration caused by corrosion pits has a significant influence on the decrease of rupture extension ratio but it is ignorable on the nominal strength ratio.

实验结果表明：锈蚀钢筋与未锈钢筋的名义强度比可近似取锈后钢筋的最大残余面积率，受锈坑应力集中的影响甚微；锈蚀钢筋的断后延伸率随最大截面损失率呈指数下降，受锈坑应力集中的影响显著。
