上台阶

He slept on doorsteps in fine weather and in empty hogsheads in wet

天气晴朗的时候，他就睡在门口台阶上；下雨时，就睡到大空桶里。

On the broad marble steps of the duomo there were scattered groups of beggars and gossiping talkers.

主教府宽阔的大理石台阶上，散布着一群群的乞丐和聊闲天的人。

They all seem to look alike-lean,pointed, dedicated faces,wearing jeans and sandals,eating their buns and bedding down for the night on the flagstones outside the theatre to buy the 20 seats and 80 standing room tickets held for the sleepers and sold to them when the box office opens at 10∶30 a.m.

译文」 他们长相一样--瘦削、专注的面孔，穿着牛仔服和凉鞋，啃着面包，在剧院外的石板台阶上席地而卧，等着购买20张坐票和80张站票，这些戏票是剧院会为席地而卧的人预备，并在早晨10∶30向他们出售。

The results show that, for the elasto-plastic contact of tip-substrate approach and separation process, the material plastic yielding in the atomic level is still governed by the von Mises criterion. For the adhesion of flat-ended wedges, continuum mechanics can be still applied down to a few lattice constants within the contact region, and give reasonable results, apart from the discrepancies near the contact edges. Moreover, adhesion hysteresis occurs during unloading due to the atomic steps, where the unloading curve does not coincide with the loading one. This in turn supports the presumption proposed by Pollock for the adhesion of stepped spheres.

本文首先对针尖—基体模型的弹塑性接触机理进行了深入研究，指出在原子水平上材料的塑性屈服仍由Von Mises准则控制；对平底锥冲头粘着接触的模拟表明，除了在接触区边缘附近有一定差别外，接触力学方法在接触区内几个晶格常数范围内仍能给出令人满意的结果；由于原子台阶效应，加载与卸载曲线不重合，出现粘着滞后，证实了Pollock关于具有纳米阶梯结构的球体粘着滞后现象的推测。

These features, along with high-precision processing technologies have helped to miniaturise these products. The micropump is 6.0mm in diameter and 24.0mm in length, the microvalve measures 3.5mm in diameter and 10.3mm in length. The products are small but ensure high functionality by incorporating fluid, structure and magnetic field analysis simulations. Development will contribute to enhanced miniaturisation, an indispensable prerequisite for portable device fuel cells. Through the optimal design of diaphragm operations, valve configuration to prevent fluid backflow, materials and layout, Alps has achieved the effective control of larger amounts of fluid in a smaller chassis for its micropump. The unit also employs low-voltage electromagnetic drive systems, which contribute to easy control and fuel cell system engineering.

There was a gas ring in the fender , and a shelf where food was kept, and on the landing outside there was a brown earthenware sink, common to several rooms

屋子里有个煤气灶，一个食物柜，外面的台阶上有个棕色的陶瓷水池，是几家合用的。

In winter nothing more dreary, in summer nothing more divine, than those glens shut in by hills, and those bluff, bold swells of heath.

在走廊下面，一个九岁或十岁的女孩子坐着编织东西，一个老妇人靠在台阶上，悠悠地抽着烟斗。

I don.t recommend it for the grandmas and grandpas because there are lots of stairs to climb.

我不建议年纪大的人去，那有很多台阶呀上。

Standing on the front steps of the shelter, staring down at my grungy sneakers and the oversized sweatshirt that seemed somewhat impractical in the Florida heat, I realized, perhaps for the first time, that I would never be returning home.

站在庇护所前门的台阶上，低头望着我那脏兮兮的球鞋还有过于宽松的T-Shirt；在佛罗里达这样炎热的天气里，穿这样的衣服明显不合适，我首次意识到，我将可能不再回家了。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
