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The improved determination method to determine the nacl of the heavy alkali of less salt is described in the paper, its accuracy and feasibility are verified by test, and the improved method can get good results
摘要文章針對純堿企業低鹽重堿分析中氯化鈉含量難以準確測定這一難題,提出了加大稱樣量、加熱除氨、硝酸中和除二氧化碳的改進方法,並通過實驗對改進方法的可行性和準確性進行了驗證,取得了滿意的效果。" the carbon dioxide from fossil fuels is distributed pretty evenly around the globe and not concentrated in the arctic, so it does n ' t look like we can blame greenhouse gases for the overwhelming bulk of the northern hemisphere warming over the past 27 years, " christy said
然而,熱帶地區溫度在過去27年中僅僅升高了華氏0 . 3度。 「燃燒釋放的二氧化碳非常均勻地散布在全球,並非只集中在北極。所以過去27年間出現的北半球加速變暖的情況,好像並不能僅僅責怪溫室氣體。In this paper, the solar and land - atmosphere radiation rates are calculated by modtran3 model and satellite observation as well as surface data, solar direct irradiance infrared irradiance solar heating rate and infrared cooling rate were calculated from 43 samples of sunshine day and 5 samples of cloudy day 3 samples of rainy day of different latitudes in 12 stations. the paper analyzed solar heating rate and infrared cooling rate in sunshine day, the factors such as zenith angle, water vapor and latitude were found out correlating with solar heating rate and infrared cooling rate. solar heating rate and infrared cooling rate change on the same day and at the same station
在對晴空大氣的計算中,本文對太陽的直接輻射與地氣系統的紅外輻射狀況進行了分析,並討論在不同的大氣狀況下太陽加熱率和紅外冷卻率的情況,找出與太陽加熱率和紅外冷卻率變化相關較大的因子?太陽天頂角和水汽條件、緯度;本文還進一步分析了不同緯度樣本的太陽加熱率與紅外冷卻率日變化及有雲、有雨情況下太陽加熱率和紅外冷卻率的變化情況:另外,文中通過改變二氧化碳在大氣中含量的方法,討論了它對太陽加熱率與紅外冷卻率的影響。The nucleation rates of different seeding agents are used as the initial conditions in the model, and at the same time cloud features and modification methods are paid more attention in the model. when simulating process of liquid co2, influence of thermodynamics to clouds is fully taken into accounted
在運算的過程中考慮了被模擬雲的實際特徵和當時的作業情況;在進行液態二氧化碳(一種製冷劑)的模擬時,充分考慮了製冷劑對雲體的熱動力過程的影響。In order to otain high quality zno thin films, we, for the first time, employ the plasma enhanced chemical vapor deposition ( pecvd ) to prepare high quality zno thin film at low temperature using a zinc organic source ( zn ( c2h5 ) 2 ) and carbon dioxide ( co2 ) gas mixtures. the effects of the growing condiction and the native oxide layer of si substrate on the quality of zno thin films was studied in detail. to prepare p - zno and overcome the dufficulty of reverse due to the interaction between the n atomic, we obtain high qulaity p - zno by a easy way of thermal zn3n2
