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。

In the study, we have found that when the long axis of an elliptical transducer is 2.5 times of the distance between nodal line and the plate center under free boundary condition, the depth of the first dip in mid frequency range of SPL spectrum can be greatly reduced.

从这些关系中可以得到激振器长轴是在自由边界条件下，节线到振动板中心距离的2.5倍时，中音谷会得到比较平缓的结果。

A new method called generalized displacement method, using new structural model taking into account the deformation of the nodal point and avoiding the disadvantage of stiffened nodal point model, is proposed here to calculate the displacement and the stress in adjecent point of thin-walled structure.

然后对双壁碳纳米管有限系统内管从外管中拉出时受到的轴向力进行了分析。

We found that during the growth process the double steps first grow separately and the connected by short bridge before tangential growth. After eighth or ninth layer the spiral steps would merge into intact elliptic layers. At the merging point right-handed spiral sources might appear but the left ones always overgrow it which made the whole growth topography looked like left-handed apparently. It indicated that the EAFP molecules has strong ability to adjust itself to adapt the environment. 5. Through various analysis of interactions in the EAFP crystals it indicated that there were 218 residue interactions between 12 symmetry-related EAFP molecules around one EAFP molecule, 18 strong ones and 72 weak ones .

EAFP在低过饱和度下的螺旋生长过程中会出现台阶的合并，从而表现出单-双的螺旋台阶，在小范围扫描中捕获到了这种现象，使得对螺旋生长台阶的合并过程有了更加深入的认识；并且台阶的生长受到沿晶体学b轴方向上的21螺旋对称的控制；当台阶生长至第八到第九层时，螺旋台阶会自动地形成完整的生长层，这充分说明了EAFP分子或分子簇具有良好的自身调节能力，这样在晶体生长过程中，晶体的缺陷减少，晶体质量提高，这也可说明EAFP晶体的x射线衍射能力很强的原因。
