The fact that the coordination number in the second subshell is smaller than that of α-Fe〓O〓 might be an indication that there is a small amount of FeO mixed with α-Fe〓O〓 in aerosol particles.

同时也发现，在第二配位亚层中的O离子配位数较氧化铁小，源于样品中含有FeO，且与Fe〓O〓物相有一定程度的混杂。

Oxygen and carbon isotope of the carbonate sediments separately indicate lake waterδ~(18)O andδ~(13)C_,δ~(18)O indicates the volume of the input water which is a good index of Lake water level changes;δ~(13)C_ indicates the degree of the exchange between the lake and the atmosphere and indirectly indicates the ice cover time controlled by the temperature.3. Environmental changes in Lake Sugan drainage area during the past 2670 years reconstructed by mul-index synthesis analysis indicates that during

沉积物碳酸盐氧、碳同位素分别反应了湖水的δ~(18)O和δ~(13)C_，δ~(18)O指示湖水体积变化，是湖泊水位变化的良好指标；δ~(13)C_则指示了湖水和大气的交换程度以及入流水量的大小，间接指示了温度控制下的冰封时间长短。3、多指标综合分析重建的苏干湖流域晚全新世近2670年来的环境变化显示，苏干湖2670年来流域持续变干；出现截然不同的两个大的阶段，即

O-(1-Arylseleno-3-azido)isopropyl-O-2-(N3-tegafur)alkyl thiophosphate (3a～3f) were obtained via nu-cleophilic ring-opening of sodium azide to 2a～2f in dry DMF at room temperature, and their antitumor activities were tested.

以无水N，N-二甲基甲酰胺作溶剂，室温下，叠氮化钠中对2a～2f进行亲核开环，得到O-(1-芳硒基-3-叠氮基)异丙基-O-2-(N3-替加氟)乙基硫代磷酯。

Compared with the classic fuzzy classification algorithm, which is based on the computation of the transitive closure of a given relative matrix and of the O(n3log n) time, the new algorithm decreases O time factor at least.

与经典的基于模糊传递闭包计算的模糊聚类算法的O(n3log n)计算时间相比，新算法至少降低了O时间因子。

The crystal belongs to triclinic, space group P-1 with α=0.775 1(2) nm, b=0.837 7(2) nm, c=1.003 7(2) nm,α=75.57(3),β=83.05(3),γ=86.08(3), D=1.296 g/cm^3, Z=2, F(000)=256,μ=0.095 mm^(-1), and the final deviation factor R=0.0545 and wR=0.146 0. X-ray analysis reveals that molecules are linked by intermolecular O-H…O hydrogen bonds formed between the adjacent molecules.

具体测定结果如下：该晶体属于三料晶系，P-1空间群，α=0.7751 (2) nm， b=0.8377 (2) nm， c=1.0037 (2) nm，α=75.57 (3)，β=83.05 (3)，γ=86.08 (3)， D=1.296 g/立方公分，Z=2， F(000)=256，μ=0.095 mm^(-1)，最终偏差因子分别为R=0.0545，wR=0.1460.X-射线衍射分析表明，分子之间通过相邻分子间形成的O-H…O氢键相连。

Structural and density of state analysis shows the interaction of O atom and surface is the total contribution of valance orbital of O atom and hybridized surface orbital of NiTi alloy.

态密度分析和结构分析表明，O原子与表面的相互作用主要是由O原子价轨道和NiTi合金杂化表面轨道贡献。

O. Henry was the pen name of American writer William Sydney Porter (September 11, 1862–June 5, 1910), whose clever use of twist endings in his stories popularized the term O.

O。 亨利是美国作家威廉悉尼搬运工(9月11 日， 1862 6月5 日1910 的)笔名，对转弯结尾的聪明的用途在他的故事通俗化期限O。

The effects of degree of acylation of chitosan and addition of lecithin on the behavior of O, O-dilauroyl chitosan self-assembled vesicles were studied in this work.
