摘    要：本文提出了包体经爆裂后、高温封闭提取的有关条件,并实验证明了该法有效地、定量地提取包体液相中的组份;拟定了包体液相的提取与测定方案;用阳极溶出伏安法测定了包体液相组份中的Cu、Pb、Cd、Zn的含量。本法具有灵敏度高、称样量少、简便、污染少等优点。

Abstract: A condition relating to the extraction of inclusion at high temperature andin enclosed system after explosion is discussed in this paper. It has beenproved by experiments that the method is effective and quantitative in extract-ing the liquid phase composition of inclusion. We have drawn up a proce-dure relating to the extraction and determination. The amount of copper, lead,cadmiun and zinc in the liquid phase composition of fluid inclusions was de-termined with the help of anodic stripping voltammetry method. The advantagesof this method are as follows: 1. The sensitivity is high. 2. The amount of weighing samples is small. 3. The contamination is only to a small extent. 4. The procedure is simple and convenient.
