一、前言在中子活化分析中通常采用密封石英瓶汞标准。然而,它并不是一种理想的辐照汞标准,还存在一些问题有待解决。据文献[1]报道首次将流基联在棉花的大分子链上,制成了用来吸附宫集有机汞、无机汞的巯基纤维。据此,我们制备了一种新的用于反应堆中子 First, the introduction of neutron activation analysis is usually sealed quartz bottle mercury standard. However, it is not an ideal mercury exposure standard and some problems remain to be solved. According to the literature [1] reported for the first time will flow base linked to the cotton’s macromolecular chains, made of the adsorption of organic mercury, inorganic mercury mercapto fibers. Accordingly, we have prepared a new reactor for neutron
