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。

Sessile spikelet longer than rachis internode; lower glume elliptic-ovate to oblong, papery to leathery, 5–9-veined, marginally 2-keeled, keels pectinately spiny, often winged at apex; upper glume 3-veined, keeled along midvein, otherwise almost flat, often narrowly winged on lower keel; lower floret staminate, palea present; upper floret bisexual, upper lemma entire, awnless.

无梗小穗长于轴节间；下部颖片椭圆状卵形到长圆形，纸质到革质，5-9脉，具刺的2龙骨状，龙骨状的pectinately，通常具翅的在先端的稍微； 3脉的上面颖片，龙骨状沿中脉，几乎平的否则，龙骨状的通常狭翅在下部；雄蕊花的下部的小花，内稃宿存；全缘的上面小花两性，上面外稃，。

Inflorescence a raceme with 2 or 3(–6) spikelets, rarely a panicle with many spikelets, peduncle, axis, branches, and pedicels slender, glabrous, scabrous or pubescent along longitudinal angles, branches usually subtended by a scaly bract at base. Spikelets ± compressed at maturity, several to many florets; rachilla disarticulating below fertile florets, extended beyond palea of uppermost floret, internodes flattened or concave on side facing floret.

花序为一总状花序具2或3(-6)小穗，一圆锥花序具很多小穗，花序梗，轴，分枝和花梗纤细，沿着纵向的有棱的无毛，粗糙的或短柔毛的很少，成熟时的小穗多少压扁，数枚到多数小花；在肥沃的小花下面脱节的小穗轴，在最重要的小花的内稃以外延长，在边面对小花上节间被变平或者凹。

Nevertheless the police keep an eye on him, and the result is a highly dramatic situation which once gave rise to a fraternal and memorable cry; that cry which was celebrated about 1830, is a strategic warning from gamin to gamin; it scans like a verse from Homer, with a notation as inexpressible as the eleusiac chant of the Panathenaea, and in it one encounters again the ancient Evohe.

不过警察是在注视着的，从而出现了一种具有高度戏剧性的情况，有一次还引起了一种兄弟般的和难忘的呼声，那种呼声在一八三○年前夕是出了名的，那是野孩和野孩间的一种战略性的警告，它的韵律象荷马的诗句，带着一种音调，几乎和巴纳德内节①的埃莱夫西斯②的朗诵调一样无法形容，并且使人想见远古的&哎弗哎&③。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。

Go down on one's knees;kneel down

屈膝跪下。。。下跪祈祷
