臂环

A microring and a phase modulator are coupled to each arm of a normal Mach-Zehnder modulator respectively in order to compensate its sublinear characteristics transfer.

将一个微环谐振器和一个相位调制器分别加载到马赫曾德尔调制器的两臂，可以补偿普通马赫曾德尔调制器的亚线性，得到线性度良好的响应特性。

First, one of the termini of 1,3-diethynylbicyclo[1.1.1]pentane was coupled with a brominated aza heterocycle, and second, 3 equiv of the resulting extended arm were coupled with 1,3,5-triiodobenzene or 4 with 1,2,4,5-tetraiodobenzene.

首先，一个总站的1，3 - diethynylbicyclo [ 1.1.1 ]戊烷是加上溴化杂环字，并第二， 3相当于由此产生的延长臂被加上1，3，5 triiodobenzene或4 1，2，4，5 - tetraiodobenzene 。

The outer structure does exhibit tidal features, as does the symmetry of the inner spiral pattern and the kinked arms just beyond its inner ring.

外围结构展示出了潮汐特征，对称的内螺旋和卷曲的臂刚刚超越了它的内环。

The new chainset is a certain hit among gram watchers and details like the retaining circlips on the rear derailleur pulley wheel bolts are definitely positive, though they\'ll be even more so when they trickle down to more affordable rear derailleurs, a component many of us feel has to be treated as expendable.

新的大飞组件对于那些对重量吹毛求疵的人来说是个打击，一些细节，比如后拨链器摆臂滑轮轴的卡环，是十分有效的改进，尽管这样的特性将在将来的低端产品中体现，但对大多数人来说，这些零件仍是昂贵的消耗品。

NGC 3808 is a nearly face-on spiral galaxy with a bright ring of star formation and several prominent dust arms.

NGC 3808是一个星系盘面几乎朝向我们的漩涡星系，由一个明亮的恒星环和数条显著的尘埃旋臂构成。

The complexing properties of compounds 10a, 10b, 11a and 11b toward alkali metal ions were studied by 〓H NMR titration, ESI-MS, UV-Vis spectra, Fluoresence spectra and liquid-liquid extraction. The results show:(1) the 1:1 complexes were formed.(2) The calix-crown 10a, 11a have a higher selectivity for Na〓 ions, whereas 10b, 11b for K〓 ions.(3) The complexing ability toward alkali metal ions was enhanced when the calix-crown have side arm carbonyl.(3) The coordination of alkali metal ions toward phenoxy, carbonyl and crown ethereal oxygens take place by rotation around the carbon-carbon bond of carbonyl and methylene.

六，用〓H NMR滴定，ESI-MS，UV-Vis，Fluorescence，液-液萃取实验研究了10a，10b，11a和11b对金属离子的配位性质，研究结果表明：1）杯芳烃冠醚衍生物同碱金属离子形成了1：1配合物，化合物10a、11a对Na〓具有较高的配位能力，化合物10b、11b对K〓具有较高的配位能力；2）在杯冠醚环的旁边引入带有羰基氧原子的基团作为侧臂参与配位可以加强对碱金属离子的配位能力；3）金属离子分别同苯酚氧，羰基氧，聚氧醚链氧发生了配位，配位过程中侧链基团涉及到了羰基碳与亚甲基碳的碳碳键的旋转过程。

Employing high-dilute method and 5-fold excess amine prepared two new "two-armed" acyclic diamine intermediates I_a and I_b, which are also intermediates of synthesizing microcyclic compounds, and eight aromatic Schiff bases, II_, were synthesized from reaction of I_a or I_b condensing with different aromatic aldehydes. Their composition and structure were characterized by Elemental analysis, IR, UV-Vis, LIF,~1HNMR and MS. The hydrogen bond interactions and MS fragmental patterns were also discussed.3. Several novel transition metal complexes using II_a as ligand were synthesized and identified by Elemental analysis, IR, UV-Vis,~1HNMR and molar conductivity.

1，采用高度稀释及胺过量五倍的方法合成了两个具有吡啶双酰胺臂的非环二胺Ⅰ_a和Ⅰ_b，并以它们为中间体进一步合成了八个芳香席夫碱Ⅱ_a-Ⅱ_h，通过元素分析及各种波谱测试鉴定了它们的组成与结构，对化合物的UV-Vis、LIF、IR、~1HNMR及MS进行了较为详细的讨论，还探讨了席夫碱的氢键相互作用及质谱裂解方式； 2，以席夫碱Ⅱ_a为配体合成了几个新型的过渡金属配合物，并通过元素分析、UV-Vis、IR、~1HNMR、摩尔电导及DTA—TG对其进行了表征，讨论了化合物的配位情况及配体在配位中的脱质子行为。

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.

他们没有侵略性，但我大喊，并在他们的方向扔石头让他们过的线索，远离我，以防万一。

In slot 2 in your bag put wrapping paper, quantity does not matter in this case.

在你的书包里槽2把包装纸、数量无关紧要。
