The results indicated that the high level density functional theory calculations can be used to predict the 13C chemical shifts of the modified nanotubes. The calculated results also provided the characteristic chemical shifts values of nitrene (superscript -), carbene (superscript -) and 1,2- and 1, 4-fluorinated nanotubes, which would be helpful for experimental spectrogram assignments. Combined with NMR experiments, these predicted characteristic chemical shifts can be further used to monitor the addition mechanism and the extent of surface modifications on nanotubes.

Conclusion］The spinal cord is damaged severely in double-tube diastematomyelia and gradually aggravated.Operation can get symptomatic relief in many patients and terminate spinal cord lesion. So operation should be performed as soon as the diagnosis is made. The spinal cord is damaged slightly in single-tube diastematomyelia and surgery is not indicated.

结论］双管型脊髓纵裂脊髓损害重，且呈进行性加重，精细的手术治疗可以使大多数患者症状缓解，终止神经进行性损伤，确诊后应尽早手术；单管型脊髓纵裂脊髓损害轻，不需手术探查。

Before ovulation, the oviducal wall is the thickest, the simple tubular glands in lamina propria are filled with the jelly substance. After ovalation, the oviducal wall is the thinnest, the cells of the tubular glands becomes smaller. During ovulation, the lamina propria is thicker. Before ovulation and after ovalation, the change of serosa is not distinct.
