碳環核 的英文怎麼說
中文拼音 [tànhuánhé]
碳環核
英文
homocyclic nucleus-
The most important carboxylase in plants is ribulose bishosphate carboxylase ( rubisco ), which catalyzes the carboxyation of ribulose bisphosphate, the ‘ carbon - fixing ’ first step in the calvin cycle
在植物中最重要的羧化酶是核酮糖二磷酸羧化酶,它可以羧化核酮糖二磷酸,在卡爾文循環中是二氧化碳固定的第一步。In these chloroplasts carbon dioxide combines with phosphoenolpyruvate to form oxaloacetic acid, which is transported to the bundle sheath cells, where the carbon dioxide is released, then fixed by the enzyme ribulose bisphosphate carboxylase to form glycerate 3 - phosphate, the first step in the calvin cycle
在葉肉細胞的葉綠體中二氧化碳與磷酸烯醇丙酮酸結合形成草酰乙酸,后被運到鄰近的維管束鞘細胞,在那裡二氧化碳被釋放,后被核酮糖二磷酸羧化酶固定形成3磷酸甘油酸,這是卡爾文的循環第一步。On the other hand, if the mass of the star is greater than about 1. 1 solar masses, the dominate reaction will be the carbon - nitrogen - oxygen cycle
假若星體質量更大,核聚變便會主要以碳氮氧循環cno循環The net effect of the cno cycle is the same as the p - p chain. but carbon is used as a catalyst
的方式進行,這循環所造成的結果和質子質子鏈沒有分別,都是把四顆氫原子核結合為一顆氦原子核碳的作用猶如催化劑。The cno cycle is faster and more energy is produced per second. in order to effectively transport the heat energy out from the star, its core has to be convective
碳氮氧循環的反應比較快,可以產生更多能量而只有對流核心能將這些多的能量有效地傳遞出去。Since a carbon nucleus is six times more positively charged than a hydrogen nucleus, the cno cycle can only operate at the higher temperature and density provided by the more massive stars
但因碳原子核帶的電荷是氫原子核的六倍碳氮氧循環需要只有質量大星體所能提供的較高溫度和壓力才能維持。Many constituents are mutagens and carcinogenic such as alkenes, nitrosamines, polynuclear aromatic and heterocyclic hydrocarbons, amines
煙草的很多成分都會引起有機體突變以及致癌,如烯烴化合物,亞硝胺,多核芳香烴以及多環碳氫化合物和銨The followings are carried out for ballistic composite with resin matrix to realize its double function of loading and bulletproof and meet various tactics technology demands in the paper 1. the resin and reinforcement for arms ballistic system are selected and ballistic properties for composites with different resin matrixs ( improved phenolic, polyethylene, rubber, bi - phenol - a, and biamaleimide ) and different fibers ( kevlar, glass, carbon and uhmwpe fiber ) are investigated, with the aim of maxwell model to explain the matrix match principle for ballistic composites
1 、本論文從材料選擇入手,進行了復合裝甲防彈體系用樹脂、增強材料進行了選擇和研究,考核了不同樹脂類型(改性酚醛、聚乙烯、橡膠、雙酚a環氧和雙馬來酰亞胺體系) 、不同纖維( kevlar纖維、玻璃纖維、碳纖維、高強聚乙烯纖維)復合材料的防彈性能,並引入maxwell模型較好地解釋防彈復合材料的基體匹配原理。分享友人
