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。

结论长期摄入贫铀对大鼠组织脏器的损伤具有一定的时间性和组织特异性，主要损伤集中在雄性生殖系统、免疫系统和造血系统，而对其他组织的损伤不明显。

Speaking at the meeting of governors in Veanna,Austria says that Iran has not opened its nuclear facilities to more thorough inspections.He also notes that Iran is not complaining with UN's Security Council's demand to stop reaching Iranism.

在一个在奥地利维也纳召开的机构管理成员高级会议上，他埋怨道伊朗并没有使其核能设施接受更全面调查，他同时强调伊朗违背了联合国安理会的停止铀浓缩的要求。

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。

Natanz, about 100 miles north of Isfahan, is the site of an uranium enrichment plant.

The accelerative effects of mixed organic acids of malonic and other organic ligand acids on mass transfer of U in ion exchange are studied by elution development.

本文用流洗色谱法研究了丙二酸和其他有机酸组成的混合有机酸对铀酰离子在离子交换树脂中的加速传质作用。

The feldspars of topaz-lepidolite granite in Yashan late stage are P-rich albite and Kfeldspar, and the phosphorus goes into feldspar structure in the form of PAlSi〓 substitution. The phosphorus contents of feldspars vary according to their crystal habitus. In general, the feldspars of later generation have the higher average phosphorus content than that of earlier generation, and the albite contains higher phosphorus than the K-feldspar in the same generation. The zircon is highly rich in Hf, U, P and Al. The phosphorus enters the zircon structure mainly by the form of〓P〓〓Si〓, Al〓P〓Si〓 or P〓Al〓Si〓, Zr〓 substitution. The P-rich zircon is the production of the highly evolved magma, and it might be one of the important characteristic minerals of the high-P subtype granite. The manganocolumbite, manganotantalite, wodginite and titanowodginite are the main niobium and tantalum minerals.

雅山晚阶段黄玉锂云母花岗岩的长石矿物是富磷长石，磷以PAlSi〓替换方式进入长石结构中，并且在长石中的分布很不均一，一般是晚结晶的长石比早结晶的长石的磷含量高，同期结晶的钠长石比钾长石的磷含量高；锆石矿物为高度富铪、铀、磷和铝的锆石，磷主要以(Y， HREE， Fe)〓P〓〓〓Si〓〓、Al〓P〓Si〓〓、P〓Al〓Si〓〓Zr〓〓等替换方式进入锆石晶格中，富磷锆石是岩浆高度演化的结果，是高磷花岗岩的特征矿物之一；雅山含有丰富的磷锂铝石，是高磷花岗岩的主要磷酸盐矿物；铌—钽矿物主要有铌锰矿—钽锰矿、锡锰钽矿—钛锰钽矿、细晶石等。
