查询词典 uranium

Ordos basin accumulates various energy resources. Taking the oil, gas, coal and uranium in the basin as subjects, the scientists of China's State "973" multi-energy minerals enrichment project study the scientific issues of interest concerning the coexistence and accumulation of energy minerals in one basin, such as the material base and geodynamical settings the accumulation mechanism and enrichment environment, and the temporal and space distribution and control factors. This interdisciplinary study provides a new perspective on comprehensively understanding energy geosciences.

我国国家&973&多种能源矿产项目的科学家以富集多种能源矿产于一身的鄂尔多斯盆地为研究地区，以油、气、煤、铀为研究对象，探讨能源矿产同盆共存富集成藏的物质基础与地球动力学背景、成藏机理与富集环境、时空分布与主控因素等科学问题，这是通过多学科交叉综合研究能源地球科学的新视角。

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。

The gray and grayish green sandstones formed by hysterogenic reduction can be used as the lithogeochemical markers for exploration of uranium deposit.

由烃类流体产生的后生还原作用所形成的灰绿色砂岩可作为铀矿床的岩石地球化学勘查标志。

In recent years, although multichannels (more than 256) gamma ray spectrometer has been made overseas, field gamma ray spectrometric survey is only used to determine contents of uranium, thorium and potassium, by reason of applying gamma ray spectrometry later than developing instruments, can't obtaining full spectrum because of the problem of stabilizing gamma ray spectrometric peaks, and it is impercipient for field gamma ray spectrometry.

作者分析了国内外野外地面伽玛射线全谱测量存在的问题主要是：（1）目前国内外野外地面伽玛能谱测量中主要使用四道能谱仪，仅利用能量大于1000keV的伽玛射线，通过数个谱段的读数结果，计算铀、钍、钾的含量，而没有利用伽玛射线全谱，使80％以上的伽玛射线能谱信息摒弃未用。

The perplexing fact is that by making some simple calculations with the available data, one is struck by the recognition, that already in the immediate future (2015) the percentage divisions between the renewable and the non-renewable sources will have to be inverted, simply to avoid that half of the world's population dies of hunger. The studies regarding the peaking of the world oil supplies and world uranium supplies has irrefutably confirmed the above stated prediction.

目前的复杂状况是，根据现有数据做出的一些简单结论中有一点是公认的，即在不久的将来（2015年），可循环能源和不可循环能源的利用比例将完全颠倒，这也只是为了避免世界上半数人口死于饥饿，而关于世界石油供给和铀供给的距增的机关研究也绝对地证实了上述预言。
