摘　　要：工业粉尘的实时监测是预防粉尘爆炸的重要手段之一。本文采用双光路激光系统，对亚麻尘的相对浓度进行了连续测量，具有测量范围宽、灵敏度好、抑制激光强度起伏噪声等特点。The continuously monitoring of industrial dust is one of important method to prevent dust explosion. The two laser beam system has been used to measure the relative density of linen dust, with the feature of wide measurement range,good sensitivity and restraining the intensity fluctuation noise.
