矽肺是指长期吸入含游离SiO_2的生产性粉尘而引起的一种慢性职业病。有关矽肺的发病机制问题,文献报导很多。已提出的学说与假说,有机械学说、化学毒性学说、聚合学说、放射能学说,压电学说、石英表面晶格学说和免疫学说等,以上各种学说对说明矽肺发病过程中的某些问题,是起着很重要的作用,但要用来全面地解释矽肺发病的整个过程,尚有不 Silicosis is a chronic occupational disease caused by long-term inhalation of productive dust containing free SiO_2. The pathogenesis of silicosis, the literature reported a lot. The doctrines and hypotheses that have been put forward include mechanical theory, chemical toxicity theory, polymerization theory, radiation theory, piezoelectric theory, crystal theory of quartz surface and immunology theory. All the above theories explain some problems in the pathogenesis of silicosis , It plays a very important role. However, there is still a long way to go to explain the whole process of silicosis
