The Mathematical Model of a Pair of Ordinary Location Photos in X ray Three dimensional Testing 射线三维检测一般位置像对的数学模型
On the basis of the ordinary"β-γ synthetical method "and by application of a new principle, this paper describes a direct determination method for uranium content accord-ing to β-and γ-ray intensities. 本文在普通β-γ综合法的基础上,从新的原理出发,提出了根据样品的β及γ射线强度直接确定铀含量的方法。
The data of the induced TL peak temperature and peak width of the surface samples were higher than those of the deeper position samples, indicating that the TL phosphor mineral of ordinary chondrites showed obviously ordering-disordering conversion during cosmic ray exposure of the parent body. 诱导热释光数据表明,母体表面部分的样品的峰温和峰宽高于较深部位样品,说明这些样品中发光体矿物由有序态向无序态转化趋势明显。
