In order to solve the problems effectively, under the auspices of 863 plan in china, the synthesis diagnosis has been carried by means of measuring and numerical imitating the combustion chamber of refining column, and some conclusions is such as : ( 1 ) through measuring the temperature and combustion in the burning chamber of the refining column, the result shows the temperature difference on the same level is more than that in height direction, and there is a few of co in bottom of burning chamber. ( 2 ) in order to ensure normal work of flue system in lead column in the course of zinc refining, theoretic calculation and measure about the flow resistance of exhaust gas are carried through. the results of study reveal that drawing out force of chimney is inadequate, which is mainly caused by illogicality of flue construction
在研究過程中,採取了現場實測和數值模擬手段對韶關冶煉廠鋅精餾
鉛塔燃燒
室及排煙系統進行了綜合診斷,具體結果包括如下: ( 1 )完成鋅精餾
鉛塔燃燒
室內溫度測試以及燃燒狀況的測試,結果發現:
鉛塔燃燒
室內水平方向的煙氣溫度並非均勻,而且其溫差比上下方向的溫差更大,以及
鉛塔燃燒
室尾部存在co未燃燼問題; ( 2 )為了保證
鉛塔煙氣系統的正常工作,對煙道系統的阻力進行了理論計算及測試分析,結果發現:鋅精餾
鉛塔煙氣系統中煙囪抽力不夠,這主要是煙道結構不合理所造成的。
Ok well i want to redo my room kindof a dark chocolate brown and a aqua, pool colored blue, but the only comforter ive found is at pb teen and i just want some other cheaper options

On thursday afternoon we were on site for a project kick - off meeting in a conference room with carpeting so deep i dropped my pencil and decided not to bother looking for it
星期二下午,我們到現場開項目動員會,會議

Two incubation experiments were conducted to evaluate the effect of cadmium and lead applied singly on soil microbial activities and functional diversity of microbial community in red clayey soil and red sandy soil
以紅黃泥和紅砂泥兩個土屬作為供試紅壤,採用
室內培養方法對外加鎘、
鉛污染紅壤的微生物活性及群落結構進行了研究。
Anybody may blame me who likes, when i add further, that, now and then, when i took a walk by myself in the grounds ; when i went down to the gates and looked through them along the road ; or when, while adele played with her nurse, and mrs. fairfax made jellies in the storeroom, i climbed the three staircases, raised the trap - door of the attic, and having reached the leads, looked out afar over sequestered field and hill, and along dim sky - line - that then i longed for a power of vision which might overpass that limit ; which might reach the busy world, towns, regions full of life i had heard of but never seen - that then i desired more of practical experience than i possessed ; more of intercourse with my kind, of acquaintance with variety of character, than was here within my reach
我想再說幾句,誰要是高興都可以責備我,因為當我獨個兒在庭園里散步時,當我走到大門口並透過它往大路望去時,或者當阿黛勒同保姆做著游戲,費爾法克斯太太在儲藏
室製作果子凍時,我爬上三道樓梯,推開頂樓的活動天窗,來到
鉛皮屋頂,極目遠望與世隔絕的田野和小山,以及暗淡的地平線。隨后,我渴望自己具有超越那極限的視力,以便使我的目光抵達繁華的世界,抵達那些我曾有所聞,卻從未目睹過的生氣勃勃的城鎮和地區。隨后我渴望掌握比現在更多的實際經驗,接觸比現在范圍內更多與我意氣相投的人,熟悉更多類型的個性。
In this paper, soil microbial ecological characteristics and their influence mechanism in red soils contaminated with heavy metals were studied using the incubation experiment, and field investigations. some sensitive microbial ecological indexes and kinetic parameters were brought forward under the single pollution of cadmium or lead, and cadmium - lead - copper - zinc compound pollution ways, respectively, which will be useful reference for bioremediation, environmental quality evaluation and building up alert index systems in red soils polluted by heavy metals
本項目選擇紅壤作為研究材料,採用
室內培養、野外調查以及相關數學分析相結合的研究方法,探討了重金屬污染紅壤的微生物生態特徵及其影響機制,提出了鎘、
鉛單一污染和鎘、
鉛、銅、鋅復合污染下紅壤微生物學敏感性生態參數及其動力學變化特徵,為重金屬污染土壤的修復、環境質量評價以及建立有效的土壤重金屬污染預警指標體系提供有益的參考。
When the propellant was lead styphnate and nickel hydrazine nitrate, their properties of ignition and thrust were investigated under different chamber diameter and different proportion of the mixed propellant. the influence of different thruster parameters on thruster properties was calculated
