Automobile exhaust gases are considered the major source . 據(jù)認(rèn)為汽車排出的廢氣是主要來源。
Measuring method of carbon monoxide in automobile exhaust gas idling 汽車排氣中一氧化碳的測定方法
For this reason , the sensing materials for automobile exhaust gas are widely studied and exploited . in this paper , rare - earth perovskite - like complex oxide la _ 2nio _ 4 has been studies as a newly gas - sensing material used for automotive oxygen sensor 本文從la _ 2nio _ 4系稀土復(fù)合氧化物薄膜的制備方法、氣敏性、摻雜改性三方面對這種新型的氧敏材料進(jìn)行了系統(tǒng)的研究。
