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。This paper stuffed with twelve important grain and vegetable crops, studied the injury symptom, dose reaction, injury threshold value and influential factor of main pollutant so2 on various plants, tested the dynamic transformation of pod, cat, mda, soluble protein, free pro and chlorophyll of resistant plant and sensitive of these physiological biochemical transformation with plant resistant ability. meanwhile, simply studied the protective role of the five compounds on plant. the result indicated the followings
本實驗以12種重要的糧食和蔬菜作物為研究對象,研究了主要大氣污染物二氧化硫( so _ 2 )對不同植物的傷害癥狀、劑量反應、傷害閾值以及影響因素,測定了抗性和敏感植物在受到so _ 2污染后植物體內過氧化物酶( pod ) 、過氧化氫酶( cat ) 、丙二醛( mda ) 、可溶性蛋白質、游離脯氨酸和葉綠素的動態變化,並分析了這些生理生化變化和植物抗性的相互關系,同時還對5種化合物溶液對植物的保護作用進行了初步研究,結果表明: 1These rocks, and others throughout the equatorial region, are rich in sulfates, a telltale sign of water - lain sediments
這些巖石與散布在整個赤道地區的其他巖石,都含有大量的硫酸鹽,這是水底沉積的跡象。The new study tied the same genetic polymorphism to lower levels of an androgen known as dhea - s, and to lower progesterone levels
新的研究約束相同的遺傳多態現象來降低雄激素的水平(已知的硫酸脫氫表雄酮( dhea - s ) )和降低孕酮的水平。In addition, chondroitin sulfate / chitosan composite films are self - assembled through electrostatic attraction on the positively charges mica substrate. the interaction and mechanism of forming the composite films were introduced. when the concentration of chitosan is 5 mg / ml and the concentration of chondroitin sulfate is 1 mg / ml, the composite films exhibited a good miscibility at a molecular scale. this kind of composite films is promising in the field of medical materials
另外,也研究了草酸鈣在硫酸軟骨素自組裝膜上受控凝集結晶的現象,發現當硫酸軟骨素的濃度為1 . 0mg ml時在雲母表面形成的網狀基底可以誘導過飽和的草酸鈣溶液凝集結晶形成liesegang環,為深入研究尿結石中環結構的形成提供了一定的實驗依據。分享友人
