在无产阶级文化大革命的斗、批、改阶段中,我所根据病区广大贫下中农和医务工作者的要求,组成专业队伍,深入克山病、大骨节病区向贫下中农学习,展开调查研究。从1968年初到现在,在四年的时间内,我们曾对黑龙江省和陕西省病区的环境地质情况进行了典型调查,并一般了解辽宁、山西、甘肃、云南的一些情况。 In the stage of fighting, criticizing and reforming of the Great Proletarian Cultural Revolution, I formed a professional team based on the requirements of the vast majority of poor and middle-class peasants and medical workers in the ward. They conducted in-depth studies on Keshan disease and Kaschin-Beck disease to the poor middle peasants. . From the beginning of 1968 to the present, in a period of four years, we conducted a typical survey on the environmental geology of the wards in Heilongjiang Province and Shaanxi Province and generally learned some situations in Liaoning, Shanxi, Gansu and Yunnan.
