针尖

The adsorbate induced faceting can be used to fabricate single atom tip, which has applied potential for high resolution microscopy, field emission electron source, and ion source.

单原子针尖可以在高解析显微术及场发射电子源或离子源上有很好的应用潜力。

I'm counting it silently. More than 8000 days have escaped from my hand. Just like a drip drop from the pinpoint into the sea, my days has fallen in the tide of time, with neither echo nor shadow.

在默默里算着，八千多日子已经从我手中溜去；象针尖上一滴水滴在大海里，我的日子滴在时间的流里，没有声音也没有影子。

After account silently I see more than eight thousands days had gone from my hands; as without a trace and quietly as the water where on the needlepoint drip into the sea, my times drip into the time sea.

在默默里算着，八千多日子已经从我手中溜去；像针尖上一滴水滴在大海里，我的日子滴在时间的流里，没有声音，也没有影子。

If dirt is small, you can use the tip, sharpening, etc to dip stick and a brush for BREW 修版 kunyuyou, the exact location in the dirt, and wash immediately.

如果不净痕较小，可用针尖、削尖的木棍和羊毫等蘸存极少修版膏，不确不天不面在不净痕上，不独立即用水冲刷。

The mechanical properties and the electrical properties of the cantilever, such as spring constant, resonant frequency, mechanical quality factor, piezoelectric output and the noise level, determine the resolution of a AFM when piezoelectric cantilever is used as the force sensor.

在作为原子力显微镜的力传感器使用时，压电探针的机械特性，如弹性常数、谐振频率、谐振质量因子，以及电子特性如压电输出、噪声水平等决定了原子力显微镜的分辨率，而对于带有针尖和三角形前端的PZT压电探针，这些特性迄今未得到系统研究。

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。

Its STM image shows sorter SWCNTs standing-on gold film surface.The crystal grain image of gold thin film and an atomic structure highly oriented pyrolytic graphite are observed using a scanning tunneling microscope with the SWCNT tip made from the water colloid mentioned above.

用此组装技术制造了扫描隧道显微镜的针尖，成功地观测到了金晶粒的形貌像和高定向石墨的原子像。

If anyone knows how to squeeze a revolutionary economy onto the head of a pin, it might be him.

如果说有人知道如何在大头针的针尖上运行革命性经济的话，那这个人可能就是他了。

Can we make it smaller? Make it fit on the head of a pin?

能不能让它小到可以放在针尖上？

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。
