After transit through the small intestine barium enters the large intestine and its characteristics in that gut segment can be studied. The pattern of distribution of barium in the colon is always altered in patients with malabsorption syndromes. The physical basis for this alteration is analysed in a manner analagous to that used in soil mechanics. The dispersal of barium granules within the liquid-solid content of the colon is related to certain factors among which is the polarisation and electrical potential of barium particles. A technique using four radiographs which permits evaluation of barium dispersal in the colon - colonic granulometry - is described. Lastly, the authors point out the necessity of classical barium studies in identifying the rare anatomical anomalies that can be the starting point of a typical clinical coeliac syndrome.
钡剂经小肠进入大肠后，可对其在该肠段的特性进行研究。吸收不良综合征患者结肠内钡剂的分布模式总会发生改变。这种改变的物理基础采用类似于土壤力学中的方式进行分析。钡颗粒在结肠液固成分中的分散与某些因素有关，其中包括钡颗粒的极化和电势。本文描述了一种使用四张X光片的技术，该技术可用于评估结肠内钡剂的分散情况——结肠粒度测定法。最后，作者指出在识别可能是典型临床乳糜泻综合征起始点的罕见解剖异常时，进行传统钡剂检查的必要性。
