常見例句Kekule reported his discovery to a meeting of scientists. 凱庫勒在一次科學家會議上報告了他的發(fā)現(xiàn)。The German chemist Kekule dreamed of snakes biting their tails, therefore discovered the ring shape of the chemical compound benzene. 德國化學家凱庫勒夢到蛇咬著自己的尾巴,因此發(fā)現(xiàn)了化學元素苯的環(huán)狀結(jié)構(gòu)。Kekule / Delocalized Display Mode - Toggle between dashed line and alternating single-double bond representation of delocalized and aromatic bonds. kekule /局域顯示模式-之間進行切換,虛線和交替單雙鍵的代表性局域和芳香類債券。August Kekule von Stradonitz in 1865 was the first to propose the correct structure, a six-membered ring of carbon atoms, each with one hydrogen atom Bonded to it. 1865年凱庫勒首先提出苯的正確結(jié)構(gòu),是由六個碳原子組成的環(huán),每個碳原子結(jié)合著一個氫原子。A Kekule struc-ture K of a hexagonal system H is also a perfect matching (1-factor) of H. A cycle (or circuit) C in H is said to be conjugated or resonant if there is a Kekule structure K of H such that C is a K-alternating cycle. 六角系統(tǒng)H的一個完美匹配(1-因子)也叫做H的一個凱庫勒結(jié)構(gòu)。 六角系統(tǒng)H中的圈C稱為共振的,如果存在一個H的凱庫勒結(jié)構(gòu)K使得C是K-交錯圈。non Kekule compound 非凱庫勒化合物 返回 Kekule
