Industrial dustdensity is the yardstick of the ESP's efficiency.
工业粉尘排放浓度是衡量电除尘器除尘性能的标准。
2
Practice has proved these measures to be the effective way for decreasing of dustdensity.
经实践证明,这些措施是目前降低粉尘浓度的有效途径。
3
The polluted flashover voltages of insulators reduce with the increase of salt density or dustdensity, and both the influences of salt density and dust.
