Nanomaterials — whose tiny components are less than 0.1 micrometres in size but larger than molecules — are prized because their properties differ from those of their larger-scale counterparts.

纳米材料的成分不足0.1微米大，但是比分子要大一些，它们被推崇是因为其性能与比它们尺度大的同类材料不同。

XRD results showed that the nano-Co-B alloy functional film prepared was amorphous.The structure was not affected by the kind of plating method.SEM,STM and AFM showed that the amorphous film was formed by the secondary micrometres particles that were constituted by the initial nano particles.

XRD结果表明，两种方法制备的Co-B纳米合金在镀态下都是非晶态，其结构并不受沉积方法的影响，SEM、STM和AFM观察发现，非晶膜镀层是由纳米相微粒构成微米级的二次颗粒，二次颗粒堆砌形成薄膜。

Micrometres of synthetic porous spherical particle shape and the LiMn2O4 preliminary electrochemical performance test results showed that in 25 degrees, porous balls and particles LiMn2O4 batteries in high-voltage areas (4V), the first charge and 112mAh/g 123mAh/g capacity respectively, 112mAh/g 123mAh/g and discharge capacity respectively.

The total precipitation for the law synthetic micrometres belt burr of Tansuanli (Li2CO3) and carbonic acid manganese (MnCO3) ball for damages caused calcine material prepared by a porous spherical type of spinel LiMn2O4 as a lithium-ion batteries positive materials, and through the valuable objects to the modified surface active agent, scattered porous ball into nano particles.

高手帮我翻一下。谢谢本文以共沉淀法合成微米级的带毛刺的碳酸锂（Li2CO3）和碳酸锰（MnCO3）球为前驱物通过高温煅烧而制备出多孔球状的尖晶石型LiMn2O4作为锂离子电池的正极材料，同时通过对前驱物加表面活性剂的改性，分散多孔球而成为纳米粒子。

The researchers now need to miniaturise their prototype, making it 100 times smaller than its current size, which is a few millimetres.

但是研究人员需要将他们的原型设备缩小100倍，即几个微米。

At present, laser process technology develops fast, since a laser light can obtain many good characteristics such as good direction, high energy density to focus the beam at a micrometer level, small pulse width ranging from dozens of Nanoseconds to dozens of Picoseconds, heating material immediately, decreasing heat effect on materials and so on.

由于激光束具有良好的方向性和高能量密度，可将光束聚焦到微米量级；由于激光束的脉冲宽度可达数十纳秒到数十皮秒，能够快速加热，对材料的热影响效应减小；因此，激光的以上优点为微加工提供了有利的条件，同时也促使激光加工技术迅速发展。

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）。
