Through the contrast analysis on the chemical constitution of the magnetic iron ore and the plagioclaseamphibolite in Nanling ultra poor magnetite, and the analysis of graphs of and (FeO+Fe2O3+TiO2)Al2O3MgO, combining the geological features of mining area and the ore body characteristics, the conclusion can be drawn as follows: the plagioclaseamphibolites including magnetite and the plagioclaseamphibolite in Nanling mining area are formed from the oceanic tholeiite with rich iron after the deteriorating, and their genesis types should be the ultrapoor iron deposit of weathered residual origin.

通过对南岭超贫磁铁矿的磁铁矿石、斜长角闪岩化学成分的对比分析，结合矿区地质特征和矿体特征，对矿体进行n-n和w( FeO+Fe2O3+TiO2)-w(Al2O3)-w 图解分析，结果显示南岭矿区的含磁铁斜长角闪岩和斜长角闪岩是大洋富铁拉斑玄武岩经变质作用而形成的，矿床的成因类型为风化残积型超贫铁矿床。

Lo Wu Bridge is not only a narrow bridge at the time, only moving train, but no bridge unroofed shed, left to sun and rain. In 1959, the government will be the Lo Wu Bridge turned into steel and concrete bridge deck has also widened more than doubled. 1962, also stamped with an iron Peng Ding, added in the iron bridge on both sides of the iron railing, and covered the sidewalk. The 20th century, the early 70s, the author in Guangzhou Railway Administration to do secretarial work, on several occasions to the Footbridge is the first walk.

当时的罗湖桥不但桥面狭窄，只能行驶火车，而且桥身无顶无棚，任凭雨淋日晒。1959年，人民政府将罗湖桥改建成钢筋水泥桥，桥面也加宽了一倍多。1962年又加盖了铁皮篷顶，在铁桥两侧增设了铁栏杆，并铺上了人行道。20世纪70年代初，笔者在广州铁路局做秘书工作，曾多次到罗湖桥头漫步。

产品/Product：本公司主要生产灰口铸铁、球墨铸铁、蠕墨铸铁。

Al impurity, the floatabilities of hematite and aegirine were resemble, which is contributed to the existence of structrual iron ion on surfaces of both minerals. It is the structrual iron ion that accelerates the floatability of aegirine greatly and leads to difficult separation with hematite. 2. The basic mechanism of actions of fluorosilicate salts as selective depressants of aegirine during the direct flotation of hematite was investaged detaily by using FTIR and XPS spectrocppy, fluorosilicate salts are poor depressants for hematite, but are very strong depressants for iron-containing silicate such as aegrine in weakly acid medium, which can enlarge the flotation differences between two minerals.

Aiming at the currently shortage of XML streams quality detecting, this paper proposes a new forecasting method of XML streams quality by least squares support vector machines, which is used the method of XML keys' vector matrix as windows, and vector product wavelet transform to multilevel decompose and refactor the XML streams series, that can fulfill real-time checking demand of XML quality, and ensure constraint, consist- ency and integrality. For even more adapting net load, it proposes a control strategy by weight and adaptive adjustment to ensure XML streams quality.
