本文对新疆巴州地区63例Ⅰ期煤尘肺类圆形小阴影的形态、大小、密集度、分布范围进行胸片动态观察,同时结合1986年与1963年新旧尘肺诊断标准进行了比较分析。结果表明,密集度升高者,其分布范围比较广泛,而分布范围广泛者其密集度不一定都增高,形态大者密集度升高的可能性亦大,升级时间较形态小者短。 In this paper, the dynamic observation of the shape, size, density and distribution range of 63 rounds of small round-shaped pneumoconiosis with small pneumoconiosis in Bazhou area of ​​Xinjiang Autonomous Region was carried out. The diagnostic criteria of new and old pneumoconiosis in 1986 and 1963 were compared. The results show that those with higher concentration have a wider distribution range, while those with a wider distribution range may not all increase in concentration, and are more likely to have a higher density of forms. The upgrade time is shorter than those with smaller forms.
