Abstract : during the heating of scrap with carbon or hydrocarbon contented substances in some process , it will bring problems like explosion of carbon monoxide , fume and smell from oil volatilization , etc . , if incomplete combustion occurs . through laboratory experiments , the time related variation of gas contents and post combustion ratio of fume during the heating of oil - bearing scrap are studied . the results show that the restrictive chain of reaction procedure is the thermolysis of oil ; that temperature and ( co ) / ( co2 ) ratio influence transformation ratio and post - combustion ratio under lower temperature ; that 900 is the temperature above which the complete reaction can be ensured at all ( co ) / ( co2 ) ratios 文摘:在某些廢鋼熔煉過程中,當爐料中含碳及碳氫物質且燃燒不充分時,會帶來煙氣中一氧化碳的燃爆、油污揮發時造成的煙霧、臭味等問題.通過實驗室裝置研究含油廢鋼在加熱過程中煙氣成分隨時間的改變以及二次燃燒率的變化,試驗結果表明,反應過程的限制性環節是油分的熱分解;在較低的溫度下( co ) / ( co2 )比例影響轉化率和二次燃燒率;而在任意比例下保證充分反應的溫度為900以上

It considers opening up the internal relation of the text as the contents , does the uniqueness and criticism as the precondition , does the emanative thought as the core and does the aggregate thought as the sustainable factor , with such three characteristics : the uniqueness , the volatilization , the restrictive , but for a long time influenced by the traditional teaching thought and cultural mentality , chinese teaching still has such severe malpractice , attaching importance to the commonness , the consult , the interclass , and the impartment , but looking down on the individuality , the process , the extracurricular , and the training 這種思維方式是以揭示文本中所包含的內在聯系為內容,以獨創性和批判性為前提,以發散思維為核心,以聚合思維為支持性因素而展開的。但是長期以來由于受傳統教學思想、文化心理的影響,語文教學仍然存在重共性、輕個性,重結果、輕過程,重課內、輕課外,重傳授、輕訓練的嚴重弊端,忽視了學生的創新意識的形成、創新能力的培養,束縛了學生人格的發展。

The content of mineral nitrogen content ( nh4 + - n + no3 - n ) decreased during the incubation period after applying nh4 + - n fertilizer and urea . it maybe relates to the nh4 + - n fixation , volatilization , and its nitrification .
