With the corrected parameter files, the results indicate that the isotopic abundance in the sample can be determined within 2 % error using a hpge detector system. artificial neural networks ( ann ) are a class of models based on neural computation and have been applied to the measurement of uranium enrichment. the principles of ann methods used in uranium measurement are presented in this paper and the conditions of analysis proceedings are described
在核保障核查測量中和實物監測中，測量對象往往是規格確定並種類有限的元件或部件，只需要關心測量對象的屬性是否發生了變化，或者對同一種類的放射性樣品的一致性做出判斷，這種要求下使用神經網路方法是比較適宜的，並且神經網路方法是與探測器和探測效率無關的。 -
This important tectonic zone parallel to the isotopic geochemical steep zone, which represented a suture line between the yangtze and cathaysian blocks. the geochemical evidence of the jianshui volcanic rocks from the sw part of shizong - mile zone shows that their lithologic types are tholeiites with the comparative flat ree patterns and enrichment in th, depletion slightly in nb, ta, and flat hfse. thus, they may be formed in a back - arc basin with the characteristics between morb and island - a
