All the compounds are characterized by IR and elemental analysis.we design and prepare a bipyridinium supramolecular compound and six coordination compounds, which are also characterized by IR, elemental analysis and X-ray structure analysis. According to X-ray structure analysis, hydrogen bonds and n-n stocking interactions participate in the architecture of three-dimensional framework [H2L1 (NO3)2 (H2O)2]n; one-dimensional zigzag coordination polymer [Hgl21.5CH3OH]n; binuclear metallamacrocycle (HgI2L2)2 3H2O; helical double-stranded one-dimensional coordination polymer [Co2(L2)2-2CH3OH]n; double-stranded one-dimensional coordination polymer [Co2(L3)2-CH3OH-CH3CN]n; and three-dimensional compound [Cu(C5H4NCOO)2(H2O)2]-H2O with hydrogen bonds, three-dimensional coordination polymer {[Cd(C5H6NCOO)2H2O]-DMF}n, which are indirectly obtained from the precursor ligand L3 through metal ion induced the hydrolysis of diamide and self-assembled with the hydrolyzate.

我们首次合成了一个双吡啶鎓超分子化合物和六个过渡金属配合物，并通过IR谱，元素分析和X-ray晶体衍射分析对它们进行了表征。X-ray晶体结构分析表明：超分子化合物[H_2L1·(NO_3)_2·(H_2O)_2]_n是由多种氢键和芳香环间的π-π堆积作用构建的三维无限结构；[HgI_2(L1)·1.5CH_3OH]_n是一维锯齿状配位聚合物；(HgI_2L2)_2·3H_2O是双核金属大环化合物；[Co_2(L2)_2·2CH_3OH]_n是具有一维双螺旋结构的配位聚合物；[Co_2(L3)_2·CH_3OH·CH_3CN]_n为一维双链结构的配位聚合物；以及由非直线形配体L3在金属离子Cu和Cd的诱导作用下发生水解，并且金属离子与水解产物——异烟酸根离子自组装，形成了三维氢键超分子化合物[Cu(C_5H_4NCOO)_2(H_2O)_2]·H_2O和三维配位聚合物{[Cd(C_5H_6NCOO)_2H_2O]·DMF}_n。

The measurements of self-diffusion coefficient,spin-spin relaxation and interproton distance at 318 K suggest that N,N′-bis-α,ω- alkane propane diammonium dibromide (16-3-16) quasi-global micelles are formed in the dilute solution at a concentration of 0.26 mmol/L and the head groups are in a saw-toothed form staying at the surface of the micelle to overcome the strong electrostatic repulsion force.

从自扩散系数、横向弛豫和质子距离等NMR测定参数推测，在浓度为0.26 mmol/L（318 K）的N，N′-双-α，ω-丙烷溴化铵(16-3-16)溶液中形成了近似球形的胶束，胶束表面的带正电荷的铵基极性头呈锯齿状排列以减弱分子间静电排斥力的影响。

Out the window over Brian's shoulder, as a stage back drop for this whole improbable scene, rose the serrated wall of the Rockies, etched in snow and ice, jagged as a giant bread knife along the western horizon.

越过布赖恩的肩头朝窗外望去，只见峰峦起伏、兀然壁立的落基山脉冰雕雪刻，犹如一把有锯齿状锋刃的巨形面包刀横贯在西部地平线上，仿佛为整个令人难以置信的场面提供了一幕舞台背景。

Methods. An elliptical or a cloverleaf-shaped indentor covering 40% of the endplate was axially compressed against the superior endplate of 48 thoracolumbar vertebrae.

The interface between pure Mo and interphase is smooth cycle, and that between pure W and interphase is discontinue one. The boundaries between interphase and TiAl matrix in both composites are serrated in as-cast condition, and the serration disappeares and smooth interphase ring is formed after HIPing.

显微组织研究表明，TiAl/Mo及TiAl/W复合材料在铸态下界面层厚度不大，且大多在TiAl基体中形成和长大，靠近Mo纤维的界面为光滑的环状，靠近W纤维的界面为微观不连续界面，而双方的另一侧以锯齿状向TiAl基体延伸。

Having indentations that extend about halfway to the center, as in certain leaves.

半裂的有锯齿状边缘的，延伸到距中心一半的距离，例如某些叶片

The front part includes the bumper that simulates the fury of the cat and the body presents a proportionate structure and ergonomics to perform jumps or stunts, while the side guards with serrated foot supports prevent the foot from sliding and keep the rider intact on bumpy tracks.

前端部分包括保险杠模拟愤怒的猫和机构提出了相应的结构和人体工程学进行跳跃或特技，而方后卫锯齿状英尺支持防止徒步滑动和保持完好的骑手颠簸轨道。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
