We also find that the metal-to-semiconductor transition can be driven by squashing the armchair nanotube along any direction. In case one starts with squashing the tube along a direction that preserves the mirror symmetry, all that needs to be done is to squash the tube to a larger extent, to a point where spontaneous symmetry breaking occurs.

我们并且发现沿任何方向压缩 armchair 碳纳米管都能够使其发生金属-半导体转变，即使我们在开始压缩碳纳米管时保持了其镜像对称性，我们所需要做的只是更大程度的压缩碳纳米管，直到出现镜像对称性的自发破缺。

The present invention relates to a polytetrafluoroethylene tube, and more particularly to a PTFE tube for a flexible hose.

To solve this problem, according to the analysis of the quality factors of the X-ray, the measurement for X-ray tube voltage/current is presented based on Q-factor and its derived QL and QH-factor when X-ray tube energy bandwidth is defined.

针对传统的管电压/管电流测量方法虽然可以检测出X射线管电压/管电流误差值，但不能反映其质量特征的状况，在分析影响X射线质量高低的因素的基础上，引入了射线管能量带宽的含义，并由此提出了基于Q值及其派生QL值、QH值的射线管电压/管电流分析方法。

After many experiments with aluminium foil of various thicknesses he was able to publish, in 1894, his great discovery that the plate of quartz that had, until then, been used to close the discharge tube, could be replaced by a thin plate of aluminium foil just thick enough to maintain the vacuum inside the tube, but yet thin enough to allow the cathode rays to pass out.

1888年莱纳德在海德堡大学昆克手下工作，他完成了他关于阴极射线的第一项研究成果，他研究了当时赫兹关于阴极射线有与紫外线相似特性的观点，并设计了一个实验，以探究阴极射线是否像紫外线一样，能够通过放电管壁上的石英窗，他获得的结果是阴极射线没有这样的特性。

Although translator has turned from being a crystal ball by which the original culture can unrestrainedly penetrate to another crystal ball by which the target culture can freely traverse, the translator's personal embodiment, in the process of cognitive act, are still absent in translation studies. Translators are still subjects without body or simply disembodied subjects.

译者虽然由原语文化可以自由穿透的玻璃球变成了译语文化可以自由穿越的玻璃球，但译者认知过程中的个体体验在翻译研究中依然缺席，译者依然仅仅是一个没有躯体体验的主体。
