查询词典 milling of ores

As for sulfur isotopic composition, the general feature of two types deposits is a single peak distribution. All δ〓s values of the ores are near zero. The difference of different deposits lies in that the δ〓s values (1. 8-5. 2‰) of LDT are of small positive value and are similar to that of the metamorphic rocks and dioritic porphyrites in the region while the δ〓s values of SDT are always near zero. Features above suggest that two types of deposits have closely genetic relationship to metamorphic and magmatic rocks.

Chemical analyses of ores sampled from different elevation at the representative Zoujiashan uranium deposit indicate that Fe〓O〓, FeO, MgO and P〓O〓 increase evidently with depth which is related to alteration of haematite, chlorite and apatite, Na〓O and Na〓O+ K〓O also increase with depth, reaching a maximum of Na〓O at 911 meters below the surface, which suggests alkaline alteration increases downwards. At depth of 90 meters below sea level, where the boundary of the two cycles of the volcanic rocks is located, CaO reaches the maximum, representing maximum of alteration of fluorite.

对典型矿床不同富集标高矿体的化学全分析结果表明：随深度增加，Fe〓O〓、FeO、MgO及P〓O〓的含量有明显增高的趋势，这与赤铁矿化、绿泥石化及磷灰石化有关；-90m标高的CaO含量最高，达17.67％，反映这一部位的萤石化最发育；Na〓O及Na〓O+K〓O的含量由浅入深也存在明显的增高趋势，且Na〓O的含量在911m深处为最高，这充分显示碱交代作用从上到下有增强的趋势，而钠长石化在911m处最强烈。

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.
