游離氫 的英文怎麼說
中文拼音 [yóulíqīng]
游離氫
英文
free hydrogen-
The free alkali metals react immediately with water to liberate hydrogen.
游離的堿金屬直接和水中作用,放出氫氣。The arsenate is usually formed in oxidation zones in contact with the atmosphere and free oxygen, and arsenic will precipitate with ferric hydroxide.
在與大氣和游離氧接觸的氧化帶中,常形成砷酸鹽,而且砷與氫氧化鐵一起沉澱。The free hydroxyl ion is involved in a further reaction with the silica network.
游離的氫氧離子會進一步和硅氧網路反應。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: 1Ionizing an atom of hydrogen takes an energy of 13. 6 electron volts, an amount delivered by a photon of ultraviolet light
游離氫原子需要13 . 6電子伏特,相當於一個紫外光光子所能提供的能量。It is not a great deal of energy ? equivalent to about 109 joules per kilogram of hydrogen, much less than the 1015 joules released by the nuclear fusion of the same amount of hydrogen
這能量其實沒有多大游離每公斤的氫需要約109焦耳的能量,遠低於等量的氫進行核融合所釋放出的1015焦耳,所以就算宇宙中只有百萬分之一的氫在恆星內進行核融合反應,也能產生足夠的能量把剩下所有的氫給游離掉。分享友人
