摘　　要：通过扫描电镜能谱分析和病理连续切片的观察证明：低矽煤尘为引起开放性肺气肿的一个条件。低矽煤尘首先引起呼吸性细支气管管壁增厚硬化和管腔扩张，称第一次开放。由于吸入的气体通过硬化性的管道冲入远端肺泡的力学效应增强，导致肺泡扩张，为第二次开放。提出了一个条件，二次开放的“低矽煤工尘肺开放性肺气肿”的新观点。By scanning electron microscopy energy dispersive X-ray analysis and observation of sections, we considered that coal dust of low silica is the condition to give rise to the thickening and hardening of respiratory bronchioar walls and the expanding of their spaces .The expansion is called first opening.When inspired air passes thrugh the hardening into the distant alveoli. They compel the alveoli to expand.This expansion is called openig, In accordance with them we proposed a new viewpoint on the formation of open emphysema in low silica coal workers’pneumoconiosis ,ie one condition and opening twice
