air enrichment 中文意思是什麼
-
The reads show that gas flow can be well - proportioned distributed in hearth, and effective quantity of gas channels increased under oxygen - enrichment operation with stable air flowrate, thus oxygen - enrichment operation with stable air flowrate is an effective way for improving the productivity of blast furnace
結果表明：穩定風量的富氧操作方式有利於煤氣流在爐缸的均勻分佈以及有效煤氣通道量增加，是提高高爐產能的有效措施。 -
The results showed that the melting ratio of silica flux decreases and the complete melting time prolongs with the size of silica flux and matte grade increasing, and the effect of the blowing air and oxygen enrichment is not remarkable in the high grade copper matte converting process
對于高品位冰銅轉爐吹煉，鼓入氣體流量和氧濃度對石英熔劑熔化率影響不顯著；熔劑粒度和冰銅品位對熔化率影響顯著，並隨著熔劑粒度和冰銅品位的增加，熔劑熔化率降低，完全熔化時間延長。 -
Several factors affecting the melting of silica flux, such as the size of silica flux, matte grade, blowing air and oxygen enrichment were discussed
主要考察了熔劑粒度、冰銅品位、鼓入氣體流量和氧濃度對石英溶劑熔化的影響。 -
The object of this research is to develop an environmental control system which can directly monitor and control the micro - environment in which plantlets were planted during the whole period of the culture ; seek the way to putrify the air in culture box ; study the effects of co2 enrichment on culture plantleto we designed an environmental control system for sugar - free plant tissue based on plc
本研究的目的是開發一套能長期自動直接監控組培微環境co _ 2濃度的調控系統；初步探索對組培箱內氣體凈化、除濕的方法；探索co _ 2富集對組培苗生長發育的影響，為日後的科學實驗和生產實踐提供借鑒。 -
In this paper introduced the study of fuzzy controller which was used for co2 supplying control from co2 source - high - pressure steel tin to culture box, studied the control of relative humidity and co2 concentration in the culture box and effects of co2 enrichment ( enrichment concentration was 900 - 1100mol mol - 1 ) on the growth of chrysanthemum plantlet and tried to clean the air in the culture box by cycling the results indicated that this environment control system operates normally and reliably. it can keep the co2 concentration and relative humidity in setting scope ; it is good to the growth of the culture plantlets to clean the air in culture box by cycling ; co2 enrichment can promote the growth and photosynthetic and can increase the percentage of shooting the number of new leaves of the chrysanthemum plantlet cultured under co2 - enriched condition is 1. 85 times of the plantlet cultured under co2 - nonenriched condition ; the number of the roots of the chrysanthemum plantlet cultured under co2 - enriched condition 5. 67 times greater compared with the plantlet cultured under co2 nonenriched condition
結果表明：所研製的無糖組培微環境co _ 2增施監控系統工作正常、穩定、可靠，能有效地將組培箱內的co _ 2濃度及其相對濕度控制在設定范圍內；用箱外循環法對箱內氣體凈化處理后，改善了組培箱內的氣體環境，有利於組培苗的生長發育； co _ 2富集環境中，組培苗生長健壯、發育良好，生根率顯著提高，根系發達。本實驗條件下，處理組菊花組培苗的新增葉片數是對照組的1 . 85倍；處理組的根總長是對照組的10 . 6倍；處理組根數是對照組的6 . 67倍。 -
