硫化現象 的英文怎麼說
中文拼音 [liúhuàxiànxiàng]
硫化現象
英文
sulfation-
Thus, such phenomena as vermilion turning black, aging of red lead and the fading of arsenic can now be more essentially represented by the chemical reactions of cinnabar having its crystal lattice transformed, lead tetroxide turned into lead dioxide, and arsenic sulfide turned into arsenic oxide
於是，硃砂變黑，鉛丹老化，石黃退色等現象，便可以用硫化汞轉變了晶格，四氧化三鉛變成了二氧化鉛，硫化砷變成了氧化砷來更本質地加以表述了。Logic : the transport of sulfur emissions across territorial boundaries contributes to poor air quality and acid rain in receiving countries
結果:跨越領土邊界的硫排放傳送而使得接受國出現空氣品質惡化及酸雨現象The process parameters of preparing nanosized titanium dioxide powders were systematically studied by electrochemical synthesis experiments at room temperature. the rutile phase and anatase phase powders were obtained in the sizes of 9. 7nm and 9. 2nm respectively, and the complete crystal powders were formed after calcined at 400 for two hours. in the process of experiments it was observed that the low current density resulted in rutile phase powders, while the addition of little amount of ions of sulfate promoted the formation of anatase phase powders
在本實驗條件下，小的電流密度有利於金紅石相的生成，而少量硫酸根離子的引入對生成銳鈦礦相粉體有利，調整電流密度大小和引入硫酸根離子的量，可以得金紅石型和銳鈦礦型的混合混體；研究無定型粉體，銳鈦礦相粉體以及金紅石型粉體隨溫度的粒徑變化情況時發現，粉體在400以前晶粒長大相對緩慢， 400以後晶粒粗化現象嚴重。Chemical industry information not merely embodyed the ordinary chemistry information substance, chemistry manufacture technological process and representative installation introduction are still have, in case contacing legal institutions sulphuric acid ? nitric acid industry system law ( ammonia oxidate law ), synthetic ammonia industry, chlorine and caustic soda are manufacture to electrolysis salt water, along with electrogilding, refine aluminium, iron - smelting and steel - smelting, cement and glass manufacture summarized account, the mineral oil is refined, hence, the chemical industry information education is contrastd against the ordinary chemistry information education, proper such representative means, be living, the means interpreted is in speech oridinarily wholly adoptd in the chemical industry information education, now most of tutors also is adopt the means interpreted in speech, cause that the chemical industry information education is insipid like this, student lack interest to chemical industry information study, but as a result of value the pair foundation, light practice, student may say the become a mere formality to chemical industry information study o since multi - med
化工知識不僅包含了一般化學知識的內容，還帶有化學生產工藝流程及典型設備的介紹，如接觸法制硫酸，硝酸的工業製法（氨氧化法） ，合成氨工業，電解食鹽水製造氯氣和燒堿，以及電鍍、煉鋁、煉鐵和煉鋼，水泥和玻璃的生產簡介，石油的煉制等，因此，化工知識教學與一般化學知識教學相比，應有其典型的方法。在過去，化工知識的教學一般都採用口頭講解的方法，現在大多數教師也是採用口頭講解的方法，這樣使得化工知識的教學乏味，學生對化工知識的學習缺乏興趣，又因重視雙基，輕實踐，學生對化工知識的學習可以說流於形式。由於多媒體的輔助教學的高效性、形象直觀性、新穎性和多樣性、人工模擬等特點，很適合化工知識的教學，應用多媒體教學化工知識可以解決目前存在的諸多問題，如：模型短缺、組織參觀活動困難、教育經費不足、學生不易觀察等。When quantity of nano - zno increased, the rubber composite materials appeared good effect on enhancing the anti - aging ability and wear - resistance but less on mechanic properties. nano - zno modified by coupling agent was applied to reinforcement of hope. mechanic properties of nano - zno / hdpe composites were investigated and compared with nano - zno without surface treatment
結果表明：納米氧化鋅具有更高的反應活性， 」非o米村料川量較少時，體系的硫化時問有延遲現象，們隨納米氧化鋅粒徑的減小和用量的增加，橡膠的硫化時間不斷縮短。Apart from sulphur dioxide, nitrogen oxides and respirable suspended particulates, which are more widely known, volatile organic compounds ( vocs ) are also critical to the formation of smog
除了較多人認識的二氧化硫、氮氧化物、可吸入懸浮粒子以外，揮發性有機化合物亦是構成煙霧現象的關鍵污染物。分享友人
