放射性样品 meaning in English

radioactive sample
radioactivesample

Standard methods of analyzing low specific gamma radioactivity samples by semiconductor gamma spectrometers
用半导体谱仪分析低比活度放射性样品的标准方法
So here , we can only say that there is a range of possible rates of senescence of the radioactive sample , and if there is a really tiny rate of senescence , that range would still include zero
所以，在这里，我们只能说，放射性样品衰老可能的速率有一个范围，如果有一个衰老的真正极小速率，那么该范围仍然应当包括零。
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
在核保障核查测量中和实物监测中，测量对象往往是规格确定并种类有限的元件或部件，只需要关心测量对象的属性是否发生了变化，或者对同一种类的放射性样品的一致性做出判断，这种要求下使用神经网络方法是比较适宜的，并且神经网络方法是与探测器和探测效率无关的。
