纳米

The nanometre powders symmetrical separate on the surface of fibre and form the composite material with larger surface and with very large adsorption capability.

这种纳米复合纤维中，纳米微粉较均匀的附在聚合物纤维表面，形成表面积很大的复合材料，具有很强的吸附能力。

At a distance of about 300 nanometres (a nanometre is a billionth of a metre), the seesaw began to tilt towards the ball.

其间距离大约为 300纳米时（1纳米是十亿分之一米），秋千开始移向小球。

Although silica nanowires with diameters ranging from ten to several hundred nanometres have been made in the past by other methods, their optical performance has been limited.

虽然过去用其他方法也做出了直径从十个到几百个纳米的矽纳米丝，但它们的光学性能受到限制。

They tweaked the composition, shape and size of the antennae until they arrived at spiral structures a few nanometres across.

他们对天线组成、形状和大小进行细致地调整直到螺旋装置的宽度只有几个纳米（1纳米为10亿分之一米）。

Fragments of flawed diamond similar in size to the smallest viruses, just tens of nanometres across, are known as fluorescent nanodiamonds.

有瑕疵的钻石微粒，即家喻户晓的荧光纳米钻石，与最小的病毒在尺寸上颇为相似，直径仅为几十纳米。

A quantum dot is a semiconducting crystal just a few nanometres across that can be engineered to absorb light of a particular colour by changing its size.

quantum dots的尺寸仅为几个纳米（1纳米=10亿分之一米）的半导体晶体，在设计时可以通过改变尺寸来吸收不同波段的光。

These miniscule sensors comprise two superconductors which are separated by an insulating layer measuring 1 to 2 nanometres, usually of aluminium oxide, with an area of 500 by 500 nanometres.

这些小尺度的传感器是由两个超导体组成，两个超导体之间由一1～2纳米的绝缘层分隔，材料为氧化铝，面积为500×500纳米。

When made into particles only a few nanometres big—a nanometer is a billionth of a metre—they shed a lot more ions and so become more potent.

当被做成几纳米的碎片时——&一纳米相当于一米的十亿分之一&——它们将能释放出更多的离子，效应因此变得更强。

The results indicate that the difference between the Y-shaped CNT and the pristine one is remarkable due to the influence of the defects in the junctions of the former.

研究结果表明，由于缺陷环的影响，Y型碳纳米管与直型管的性质明显不同，而且，Y型碳纳米管的结构和性质与分支管长度存在一定的关系。

The results show these as-prepared samples consist of a nano-CdS core and a layer of thiols chemically absorbed on the surface, and they can be stored for a long time in air atmosphere.

结果表明：该方法所制备的硫化镉纳米晶是由无机纳米核及通过化学键吸附在其表面的硫醇分子所组成。

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％。
