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.

Fund industry believes that the size of the non-return may be having with the cautious, after all, the current financial crisis on China's impact is still, and 4 trillion of investment is also difficult to make the market reverse, Sustained rebound in the cash option at a time when very real.

基金业内人士认为，非规模收益可能具有的谨慎，毕竟，目前对中国的影响，金融危机仍在，和4万亿美元的投资，也很难扭转市场持续反弹的现金选择的时候非常真实的。

Lastly, the thesis takes northern Jiang Su as an example to carry out empirical study on the basis of the thought of allocating and cultivating higher education resources through the orientation of ecology proposed above, and draw a conclusion that the general allocation efficiency of talent resources and material resources in northern Jiang Su is in a low level and furthermore, the thesis proposes the advice of adjusting the quantity of colleges and universities of different subjects, controlling enrollment scale, controlling the overhigh student-teacher ratio and change the serious"scholars take leadership"phenomenon in northern Jiang Su.

最后，根据提出的高等教育资源生态化配置与培植思路，以苏北地区为例进行实证研究，得出苏北高等教育人才资源和物力资源配置总体效率不高的结论，进而提出从调整苏北不同科类高校设置、调整招生规模、控制过高的生师比以及扭转比较严重的"学者从政"现象几方面调整苏北高等教育资源配置和培植的建议。

It proposed to establish perfect ecosystem function conservation monitoring system, to conduct some ecosystem rehabilitant and build up engineering project, and achievement; to solidify the results of return polder back to lake, and setup immigration residents. And to improve the flood regulation function capacity; Wetland and the biodiversity can be protected effectively; Basically to curtail degradation of ecosystem function, and ecological environment, people's living condition and quality will be improved greatly.
