We prepared the ordered porous alumina membrane by a two-step anodization method in oxalic or sulfuric acids, which is a self-ordered hexagonal array of cells with an adjustable pore diameter of 20-150nm and a different pore structures (i.e. Y-branched, dendriform, toothed and torous ones). Furthermore, the template-electrodeposition, vapor-catalytic growth, and controlled chemical etching were developed for well-aligned carbon nanotubes and oxide nanopillars with adjustable diameter, Al2O3-AlN one-dimensional heterojunction, Y-junction and dendriform metal nanowires, as well as Y-junction, and torous carbon nanotubes. The resultant one-dimensional junctions were characterized by XRD, SEM, TEM,HRTEM, and STM, and the field emission of the well-aligned carbon nanotubes and the luminescence of ZnO nanopillar array have also been mearsured.

完善和发展了阳极腐蚀法制备多孔氧化铝膜的方法，制备出了孔径在20-150nm之间可调和具有不同孔结构（如Y形、树枝状、锯齿状）的系列多孔氧化铝模板，在此基础上，利用电化学沉积、气相催化生长和化学控制腐蚀等方法，成功地生长出具有可调直径的碳纳米管和氧化物纳米柱有序阵列、Al2O3-AlN异质结纳米线、Y形和树枝状的金属纳米线以及Y形、藕节形和锯齿形的碳纳米管等多种一维结纳米材料及其阵列体系，探索了基于模板孔壁内沿生长一维结纳米材料的机制，较系统的研究了碳纳米管阵列的场发射性能和氧化锌纳米柱的发光性能，为低维纳米材料器件化提供了实验基础。

The stellar dendrites you see here are the largest forms of snow crystal and perhaps the most beautiful, with the sectored plates coming in a close second, but there are also less photogenic simple prisms, columns, bullet shapes and needles and crystals that combine different types.

这里看到的星状树枝雪晶，是雪晶中个头最大，可能也是最漂亮的，有瞬间凝成的扇形分割星盘状躯体，有时也呈现简单的棱柱形、圆柱形、弹头形、针形和各式不同形状组合，只是镜头不易捕捉到。

Ovules 8-14 per ovary. Fruit cylindric or oblong,(1-)1.5-3(-4) cm × 2-4 mm, straight, widest at base, narrower at apex; style obsolete or to 1.5 mm; stigma capitate, subentire or with obscure lobes as long as wide.

They are lined with pleasure domes, octagonal kiosks, maharajahs' palaces and Ottoman minarets, their lattice and lacework done in iron instead of shining marble.

它们总是与漂亮的圆顶（这个词组有游乐场所的意思，这里好像是游乐设施的意思）、八角亭、印度王公的宫殿、奥斯曼式的尖塔相伴，它们交叉的梁柱（格状桩基，应该是延伸到海底支撑整座栈桥的斜状梁架）以及装饰的花边用的是铁而不是光亮的大理石。

In the United States, chronic alcoholism and hepatitis C are the most common ones.

在美国，慢性酒精中毒，肝炎是最常见的。
