Is within the flow region, rivers rare, soil essential for the desert soil, and thick bone soil and saline soil; vegetation is extremely sparse shrubs, semi-shrubs, mainly, there are large tracts of land barren; land type is mainly mountainous and desert, erosion stone Gobi, alluvial gravel Gobi and mobile sand.

属内流区，河流稀少，土壤基本为荒漠土、粗骨土和盐土；植被以极其稀疏的灌木、半灌木为主，还有大片土地寸草不生；土地类型则主要为山地荒漠、剥蚀石质戈壁、洪积砾石戈壁以及流动沙地。

His hair was black and long, and he had a small black beard.

In Namibia, formerly South West Africa, presidential and parliamentary elections to be held on November 27th-28th are the fifth since the end of a 22-year guerrilla war led by the South West Africa People's Organisation against apartheid South Africa. Two decades on, the world's second-most sparsely populated country, with just 2.2m people spread over a territory more than three times the size of Britain, much of it desert and scrub, is a stable and peaceful multiparty democracy.

在纳米比亚在11月27-28日举行的总统和议会的选举是在持续了22年的西南非人民组织领导的游击战结束后举行地第五次选举，（SWAPO反对南非的种族隔离制度）。20年后，这个世界上第二个人口最稀疏的国家，2千万人口遍布于比英国大三倍的疆域的国家现在是一个稳定和平的多党民主制国家。

Based on the Least Squares Support Vector Machines method, Incremental LS-SVM and Online LS-SVM method is proposed for identification of structural systems in this paper. It efficiently updates a trained LS-SVM by means of incremental and decremental pruning algorithms whenever a sample is added to, or removed from, the training set. The method overcomes the drawback of sparsenesslost within the standard LS-SVM and makes online training for the LS-SVM possible.

本文在最小二乘支持向量机方法的基础上提出了用于识别结构系统的增量最小二乘支持向量机和序贯最小二乘支持向量机方法，当新样本加入进来或老的样本被修剪下去的时候可以有效地更新，这种方法克服了标准最小二乘支持向量机方法的稀疏性缺失，使得结构参数的在线识别成为可能。

We introduce an accurate online-learning support vector machine algorithm, including incremental and decremental algorithm, which efficiently updates a trained regression function whenever a sample is added to or removed from the training set.

本文充分利用支撑向量机解的稀疏性并结合KKT条件，当向训练样本集中添加新样本时，调用&递增&算法修改原有回归函数来得到新回归函数；当从训练样本集中剔除旧样本时，调用&递减&算法修改原有回归函数得到新回归函数，即在线学习方法。
