denuder

常見例句

• The purpose of this study is to understand the interferences of HONO measurements during denuder sampling.
  本研究目的在于確認環(huán)形氣固分離器應(yīng)用于大氣中HONO量測之干擾情況。
• Measurements of paniculate ammonium and gaseous ammonia in ambient air were studied by denuder difference and filter packs.
  本文用擴散管差分法和多種疊層濾膜法測量大氣中顆粒物銨鹽和氣態(tài)氨。
• Measurements of particulate nitrate and gaseous nitric acid in ambient air were studied by denuder difference and filter packs.
  研究了用擴散管差分法和多種疊層濾膜法測量大氣中顆粒物硝酸鹽和氣體硝酸。
• An annular denuder system(ADS), which consisted of denuder tubes striping the reactive gases from air and leaving the particles on the filters was designed.
  應(yīng)用環(huán)形擴散管同時采集和分離空氣中氣態(tài)組分和氣溶膠顆粒兩種狀態(tài)的污染物，解決了采集過程中氣體和顆粒物相互干擾問題。
• A new denuder technique for samplinggaseous pollutants is given and the theoryand application of cylindrical denuder and an-nular denuder are described in detail.
  本文介紹了一種新型的采集氣態(tài)污染物的擴散管技術(shù)，并且較詳細地敘述了圓柱形擴散管和環(huán)形擴散管的理論與應(yīng)用。
• So 2NO2 + H2O HONO + HNO3 is not the main formation mechanism for HONO artifact, too.In conclution, the main formation mechanism is the NO2 reducing reaction directly in the annular denuder.
  故推測干擾機制為NO2于采樣管內(nèi)直接異相還原生成HONO，而HONO干擾濃度隨著進氣NO2濃度增加而呈飽和生成曲線關(guān)系。
