【摘要】 对某矿１９５０年后入矿的煤矿尘肺和无尘肺０＋者进行肺气肿患病调查。应用肺功能的气速指数法（简称ＡＶＩ）尘肺组检出合并肺气肿占７６．６％，０＋组占６８．７％，ｘ２＝４．４８０３，Ｐ＜０．０５；尸检煤矿尘肺合并肺气肿占８８．６２％。在四种Ｘ线标准中，以Ｘ线综合标准法检出率最高为３９．０８％。气速指数优于Ｘ线各标准法。更多还原

【Abstract】 Workers, having started their job in a coal mine ever since 1950, suffered from coal mine pneumoconiosis and suspected coal mine pneumoconiosis (0+) and both complicated by emphysema, were surveyed. By applying air velocity index, velocity index, emphysema complication rate of 76. 6% was found in the pneumoconiosis group, while in the 0+ group it was 68. 7%. x2=4. 4803, P<0. 05.However, by autopsy, 88. 62% was found in the coal mine pneumoconiosis group.Among four kinds of X-ray standards, the highest of 39.08% was found by X-ray comprehensive standard. It could be noted that air velocity index is better than the X-ray standard.更多还原
