林格曼排氣濃度圖是19世紀(jì)末法國(guó)的林格曼首先提出的。他利用比色原理，將排放源出口處煙氣顏色與某一標(biāo)準(zhǔn)濃度物進(jìn)行比較的測(cè)定方法，當(dāng)某一排氣顏色與標(biāo)準(zhǔn)濃度物的顏色相接近時(shí)，就認(rèn)為煙氣濃度與標(biāo)準(zhǔn)濃度物的濃度相*。林格曼圖有多種形式，較常用的標(biāo)準(zhǔn)形式是由14X21cm的6個(gè)不同黑度的小塊組成，除全白與全黑分別代表林格曼黑度0級(jí)和5級(jí)外，其余4個(gè)級(jí)別是根據(jù)黑色條格占整塊面積的百分?jǐn)?shù)來(lái)確定的、黑色條格的面積占20％為1級(jí)，占40％為2級(jí)，占60％為3級(jí)，占80%為4級(jí)，林格曼排氣濃度圖見圖二。</span></span></p><p><span
