我国测尘技术发展缓慢,近年虽有起色,但与先进国家相比,差距仍较大。自六十年代开始一直延用至今的常规采样法(短时定点采样法)仍是目前主要的采样方法。
The dust detection technology in our country has been developing very slowly. In spite of the improvement in recent years, the gap is still relatively large compared with the advanced countries. The conventional sampling method (short-time fixed-point sampling method) that has been used since the 1960s is still the main sampling method at present.
