3. 總結 
  
       縱上所述，壓差法、稱重法、以及濕度傳感器法維護方便簡單
，隻需進行常規的維護操作就可以了。但是對於等壓法
、紅外傳感器法、以及電解傳感器法必須注意傳感器的保護、試驗尾氣的處理、測(ce)試(shi)係(xi)統(tong)內(nei)雜(za)質(zhi)氣(qi)體(ti)的(de)清(qing)除(chu)等(deng)幾(ji)個(ge)方(fang)麵(mian)

，因(yin)此(ci)對(dui)這(zhe)些(xie)測(ce)試(shi)設(she)備(bei)進(jin)行(xing)特(te)別(bie)維(wei)護(hu)就(jiu)更(geng)加(jia)有(you)必(bi)要(yao)了(le)。
