I bought that armchair for $ 48 at a sale .Isn't it a real buy ?

我花了48元买了把椅子，还算便宜吧？

Furthermore, by using Natori theory on the field-effect transistor we study the current-voltage characteristics of deformed carbon nanotube field-effect transistors. For strain deformation, the conductivity of zigzag nanotube presents different characteristics with the remainder of n and 3. For armchair nanotubes, the conductivity does not change with the strain parameter. However, for torsion deformation, the conductivity rapidly increases, specially for the armchair tube. It has many obviously different conductivity behaviors between zigzag tubes and armchair tubes.

进一步应用场效应晶体管Natori理论模拟计算形变碳纳米管场效应晶体管的电流-电压特性的影响，zigzag碳管根据n 与3的余数关系表现出不同的电流变化趋势，而对于armchair碳管轴向拉伸不改变电流；在扭转形变时，碳管电流急剧升高，特别是armchair管。zigzag和armchair管的电流随扭转角度和外电压行为明显不同。

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。

Moreover, since the strain energy of zigzag tubes is larger than that of the armchair tubes with the same semidiameter, the ends of the armchair tubes are easier to be closed than those of the zigzag ones. And the closed structures of the zigzag tubes have a lot of defects, even at 3000 K, there will be few carbon atoms flying away from them.

此外，由于锯齿型碳管应力能比同口径扶手型碳管的应力能大，使得扶手型碳管比锯齿型碳管更容易形成端口封闭的结构，且锯齿型碳管端口的封闭结构出现相对较多的缺陷，甚至在3000K下会有少最碳原子从端口飞离碳管。

Considering the curvature effect on hooping of nearest-neighboring carbon atoms of armchair carbon nanotubes, the energy band, density of state and velocity of electron of armchair SWNT were analytically derived by using the tight-binding model and Born-Karman boundary condition.

在考虑曲率效应对扶手椅型碳纳米管最近邻碳原子交叠积分影响的情况下，利用紧束缚模型和玻恩－卡门边界条件解析地推导扶手椅型SWNT的能带、态密度和电子公有化运动速度，对扶手椅型SWNT电子性质的分析发现：考虑曲率效应后扶手椅型SWNT仍然是金属管，但其能带的总能减小，其态密度的导电平台变窄且其电子公有化运动速度变小。

Especially, the difference of the nearest-neighbor hopping integral is due to the effect of the curvature of the carbon nanotubes. So, in fact there is a very narrow energy gap near the Fermi energy of unsquashed metallic zigzag carbon nanotubes, and, a slighter deformation is required to open a considerable energy gap in metallic zigzag carbon nanotubes than that in armchair nanotubes.

特别是，最近邻格点之间的跃迁积分的变化与碳纳米管的曲率紧密相关，因此实际上，理想金属型 zigzag 碳纳米管本身具有微小能隙，而施加比 armchair 碳纳米管小的多的压缩量，就可以使金属型 zigzag 碳纳米管在费米能处打开相当的能隙。

So in practically, squashing the armchair carbon nanotube can be used as a general approach to drive the metal-to-semiconductor transition.

因此在实际应用中，对 armchair 碳纳米管进行压缩能够作为一种普遍的获得金属-半导体转变的途径。

Opposite the armchair, however, in which the count's mother had died--a square armchair of formal design and inhospitable padding, which stood by the hearthside--the Countess Sabine was seated in a deep and cozy lounge, the red silk upholsteries of which were soft as eider down.

在壁炉的另一边，也就是那张扶手椅的对面，萨比娜伯爵夫人坐在一张深座椅子上，椅垫是红绸做的，柔软得像鸭绒。

五代至宋，高型坐具空前普及，椅子的形式也多起来，出现靠背椅、扶手椅、圈椅等。
