【谢绝简单用翻译软件翻译】 碳纳米管缺陷能级（带）量子化导致势垒量子化。构成悬挂键的外层电子只有吸收非连续的特定能量跃迁成相对自由状态才可能彼此成键，即处于3DB状态的C原子吸收足够能量克服势垒才能实现重构。另外，在自由3DB状态到5-1DB-P或5-1DB-T状态之间存在两套不同的非连续势垒(如图4所示)。只有当供给的能量满足某套势垒所需能量值时，才能形成相应的该套重构结构。图5是在(9, 0)碳纳米管中单空位结构优化后悬挂键原子间距的变化情况。从Figure 5可清楚看出，5-1DB-P结构的形成导致悬挂键原子间的距离均被拉近，其中，C1-C2被较大幅度拉近成键。而5-1DB-T导致一个被拉近成键，一个远离，一个不变，且5-1DB-T中被拉近后的C1-C3间距仍大于5-1DB-P 中C1-C2。这说明5-1DB-P结构相对5-1DB-T结构更加紧凑，力学性能更趋稳定，5-1DB-P比5-1DB-P能级应该更低，这和前面图3显示结果完全吻合。 [ Last edited by 168yjh on 2008-12-23 at 15:43 ] |

碳纳米管缺陷能级（带）量子化导致势垒量子化。构成悬挂键的外层电子只有吸收非连续的特定能量跃迁成相对自由状态才可能彼此成键，即处于3DB状态的C原子吸收足够能量克服势垒才能实现重构。另外，在自由3DB状态到5-1DB-P或5-1DB-T状态之间存在两套不同的非连续势垒(如图4所示)。只有当供给的能量满足某套势垒所需能量值时，才能形成相应的该套重构结构。图5是在(9, 0)碳纳米管中单空位结构优化后悬挂键原子间距的变化情况。从Figure 5可清楚看出，5-1DB-P结构的形成导致悬挂键原子间的距离均被拉近，其中，C1-C2被较大幅度拉近成键。而5-1DB-T导致一个被拉近成键，一个远离，一个不变，且5-1DB-T中被拉近后的C1-C3间距仍大于5-1DB-P 中C1-C2。这说明5-1DB-P结构相对5-1DB-T结构更加紧凑，力学性能更趋稳定，5-1DB-P比5-1DB-P能级应该更低，这和前面图3显示结果完全吻合。 The quantization of carbon nano-tube defect energy level (band) causes the quantization of potential barrier. Only when the outer electrons forming dangling bonds absorb noncontiguous specific energy and transit into relative free status, can they bond with each other, that is, only when C atom in 3DB status takes in enough energy and conquers potential barrier can it realize reconstruction. In addition, between free 3DB status and 5-1DB-P or 5-1DB-T status, there are two sets of different noncontiguous potential barrier (shown in Fig.4). Only when the supplied energy meets the required energy value of certain set of potential barrier, can the corresponding reconstruction of this set be formed. Fig. 5 shows the change of interatomic distance of dangling bond after single vacancy structure is optimized in (9, 0) carbon nano-tube. From Fig. 5 it can be clearly seen that, the form of 5-1DB-P structure causes the interatomic distance of dangling bond to be drawn nearer. Among them, C1-C2 is drawn nearer to form bonding to a fairly large degree, while 5-1DB-T causes one to be drawn nearer to form bonding, the other to be drawn far away, and another stays unchanged.Moreover, after 5-1DB-T is drawn nearer, the space between C1and C3 is still bigger than the space between C1and C2 in 5-1DB-P. This indicates that the structure of 5-1DB-P is more compact than that of 5-1DB-T, and its mechanical property is more stable, and the energy level of 5-1DB-P should be lower than that of 5-1DB-P, which accords with the results shown in Fig.3.

原文最后一句似乎有点问题，请楼主自己修改一下吧 似乎应为5-1DB-P比5-1DB-T能级应该更低 最后一句英文相应改为This indicates that the structure of 5-1DB-P is more compact than that of 5-1DB-T, and its mechanical property is more stable, and the energy level of 5-1DB-P should be lower than that of 5-1DB-T, which accords with the results shown in Fig.3.
