查询词典 enriched uranium

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.
