用Ｘ射线衍射法对１８例人体胆囊结石的结晶进行测定分析，并与８０年代初的分析测试结果进行了比较．结果表明：颗粒状的人体胆囊结石，尽管其外观和剖面结构各不相同，但都以结晶态物质为主，其主要成份为胆固醇；泥沙状结石以非晶态物质为主，其主要成份为胆色素或胆色素盐；与１０ａ前的测试结果相比，胆固醇性结石的比例显著升高而胆色素类结石比例相对下降 X-ray diffraction method for the determination of 18 cases of human gallstone calcification analysis and analysis and test results of the early 80s were compared. The results showed that: the granular human gallstones, although their appearance and cross-sectional structure vary, but are mainly crystalline substances, the main component of cholesterol; sediment-like stones with amorphous material, the main component For the bile pigment or bile salts; compared with the pre-10a test results, the proportion of cholesterol stones increased significantly while the proportion of biliary pigment stones decreased
