Capillarity The rise or fall of liquids in narrow tubes as a result of the surface tension of the liquid, which causes the water to adhere to solid surfaces, such as soil particles or the walls of xylem vessels.

毛细现象：由液体表面张力引起的液体在细管中上升或下降的现象，毛细现象引起水和固体表面的粘合作用，例如土壤颗粒或木质部导管壁。

When the proper temperature is reached, the alloy will flow readily into the space between the tube outer wall and the fitting socket, drawn in by the natural force of capillary attraction.

当温度加热到一定程度，合金将流到管道外壁和管件插口内壁之间的空隙中，这种吸入作用是通过毛细吸引的自然力实现的。

I have referenced this with a graduate wall thickness of the carafe – with at robust thickness at the bottom and less thickness at the top.

Based on this model, the structures, dipole moments and the nuclear magnetic resonance parameters were calculated for a series of functionalized nanotubes, including nitrene and carbene modification, as well as 1,2- and 1,4-fluorination.

本文采用C80H20模型来表示(10，0)碳纳米管，基于此模型计算了一系列氮烯、卡宾和氟化的单壁纳米管的结构、偶极矩，以及核磁共振参数。

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.

研究表明高精度的密度泛函理论计算能够用来预测纳米管的13C化学位移，理论研究的结果揭示了氮烯、卡宾以及1，2和1，4氟化的单壁纳米管的若干13C信号特征化学位移值，为实验NMR谱图的归属提供了一定的依据，并且可通过与实验相结合来监测表面官能化碳纳米管加成反应是否发生以及确认其加成方式。
