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。

In the early days, spelling was taught by reading a word aloud from the speller letter by letter and syllable by syllable:"o, r-or; d, I-di, n, a-na; r, y-ry; ordinary."

早期在拼写法的时候，都是按照拼写课本每个字母，逐个音节地高声朗读，如"o， r-or； d， I-di， n， a-na； r， y-ry；连起来念ordinary"。

And then different kinds of intramolecular N-H…O=C hydrogen bonding energies for peptides were evaluated by the substitution method.

在说明取代法的合理性后应用此方法计算α-和β-多肽结构中不同类型的N-H…O=C分子内氢键键能。

In this paper, a method was proposed to evaluate the intramolecular N-H…O=C hydrogen bonding energies for peptides. The reasonability of the substitution method was explained.

本论文的主要研究任务是设计一种能够计算多肽和蛋白质体系中N-H…O=C分子内氢键键能的新方法。

Self-assembled nanomicelles of N -cholesterol succinyl O -carboxymethyl chitosan were prepared by probe sonication method. The amphiphilic property and the critical micelle concentration of CCMC were determined by fluorescence probe technique; the morphology and the size of CCMC self-assembled nanomicelles were analyzed by transmission electron microscopy and the dynamic laser light scattering.

以 N -胆甾醇琥珀酰基- O -羧甲基壳聚糖(CCMC，胆甾醇基取代度6.9%)为原料，在水溶液中通过探头超声处理制备其自组装凝胶纳米胶束，采用稳态荧光探针法考察临界胶束浓度，并通过透射电镜和动态激光散射仪检测胶束的形态大小。

O'rodusk N'urncer, a legendary Altmer blacksmith from Summerset Isle, was renowned far and wide for his amazing craftsmanship, and knights, heroes, kings, lords and many other people of importance from around Tamriel would risk life and limb simply to request a weapon from him.

奥诺达斯科·努恩瑟（O'rodusk N'urncer）是一个传奇的夏暮岛高精灵铁匠，以其令人惊异的手艺而远近闻名，全泰姆瑞尔的骑士们、英雄们、国王们、领主们和许多其它举足轻重的人们都愿意奔波万里，甚至冒生命危险来找他，只为了求一把他制造的兵器。

The Mg-O bonds, the Raman frequencies and the number of the v〓-SO〓 band of the ion pair chain〓(n=1-4) increase with the growing of the chain, and it is well consistent with the experiments. It explains that the phenomena of gel appearance in the supersaturate solution of MgSO〓 and the blue shift of Raman spectra, as well as the phenomena of FWHH getting wider.

在〓（n=1-4）离子对链中电荷交替分布，Mg-O键长随链增长而增长，拉曼光谱频率随链增长而增高，最大强度振动波段的数目随链增长而增大，这些计算结果解释了MgSO〓过饱和溶液中出现的凝胶现象和其拉曼光谱的波段蓝移和半峰宽变宽的变化。

Methods Naloxone was synthesized starting from oxidation of thebaine, followed by hydrogenation, acylation, cyanidation, O-demethylation, hydrolyzation and N-allylation. The alternative method of O-demethylation, methane sulfonic acid/DL-methionine and hydrobromic acid were investigated.

在以蒂巴因为原料，经氧化、氢化、酰化、氰化、去氧甲基、水解、N-烯丙基化得到纳洛酮的合成路线中，分别采用甲磺酸／DL-甲硫氨酸和氢溴酸代替三溴化硼进行去氧甲基化和后续水解反应。

At the same time, increasing the negative charge of O at C7 and N at thiazole in C15 sidechain is favorable.

同时，C7上的O原子和C15侧链噻唑基团上的N原子的负电荷的增加，对epothilones的生物活性的增大也是有利的。

N?-o Roman Mythology A tutelary deity or guardian spirit of a person or place.

n？-o 守护神：一个人或地方的保护神或守护神

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).
