查询词典 ionic bond

The three isomers structures of 3 were discussed in detail based on the calculation results. Among the six bonds in 3, the P_O bond between the phosphorus and carboxyl oxygen O3 was the weakest one, and could be easily broken to form a new penta-coordinate intermediate 4 which could yield the phosphoryl N → O migration product 5 by breaking the weaker P_N bond.

在六配位磷中间体3的6根键中，丝氨酸的羧基氧O3与磷之间的键最弱，最易断裂生成新的五配位磷中间体4， 4的P_N键断裂得到磷酰基的N→O转位反应产物5。

用Ritz变分法求出了氢分子离子H2 +基态能量附近的能量随变分参数和分子键长变化的数值关系，并用抛物线插值法获得了H2 +键长和基态能量的值及其计算公式，比文献 [1，2 ]更接近于实验值。

Among Lee's most memorable performances are Rochefort in three Three Musketeers movies, Sherlock Holmes, classic James Bond villain Scaramanga in The Man with the Golden Gun (Lee's cousin, author Ian Fleming, created Bond), and, of course, nearly every classic monster in the book for Britain's hit Hammer horror films of the 1950s and '60s: his breakthrough role in The Curse of Frankenstein (he was the monster to Cushing's mad doctor); the title role in The Mummy; double duty as Jekyll and Hyde; and, most famously, his solitary yet deadly Count Dracula, whom he portrayed more than any other actor, beginning with 1958's Horror of Dracula, which pitted him against Cushing as Van Helsing, and lasting until 1974 with The Satanic Rites of Dracula.

在李最令人难忘的表演中，有电影《三剑客》中的罗切福特，夏洛克·福尔摩斯，经典的《金枪客》中詹姆斯·邦德的对头斯卡拉曼加（李的堂兄，作家伊恩·弗莱明创造了邦德），当然还有英国二十世纪50~60年代中几乎每一部经典恐怖片中都要出现的怪物：他在《弗兰肯斯坦的诅咒》中的突破性演出（他是库欣扮演的疯狂教授创造的怪物）；《木乃伊》中的木乃伊；双重性格的哲基尔和海德；还有那个最著名的，孤独而又致命的德库拉伯爵，他对这个角色的演绎次数远远超过其他任何演员，从1958年的《恐怖的德库拉》开始——在该片中他对抗库欣扮演的范·海尔欣，一直到1974年的《德库拉的恶魔典礼》。
