| 摘 要： | 用Ｓｉ（Ｌｉ）探测器实现了Ｎａ、Ｍｇ、Ｓ、Ｃｌ的特征Ｘ射线在有机膜中的相对衰减以及与Ｏ、Ｋ元素的特征Ｘ射线能量相当的Ｘ射线或轫致辐射在有机膜中的相对衰减，分别得出了它们减的数学描述，并把实验得到不同能量的Ｘ射线在有机膜中的质量吸收系数与Ｂｅｒｋｅｌｅｙ的ＯＣＧ软件计算出的结果相比，相关都小于３０％。

| Abstract: | The characteristic X-rays of Na,Mg,S, Cl and O, which are considered as constituent elements of plant seeds, are measured with a St(Li) detector when penetrating several layers of Mylar or Capton films. The measured absorption coefficients for different energies are compared with the calculated ones based on the OCG program written by Berkeley group in 1989. The relative error is less than 30%. The range of the characteristic X-rays is estimated. |
