The following results were obtained: 1. Several multi-pore materials were compared and a nylon membrane was choosed to conduct experiments. 2. Two devices and methods for controlling negative hydraulic heads were developed. Coupled with the devices, a system for precise control of soil moisture udring pot experiment was developed. 3. Two times of pot experiment studying wheat seedling growth under precise soil moisture control were conducted. Some very important results were obtained. 4. Capillary rise, horizontal and vertical infiltration under different nagative hydraulic heads were observed. The concepts of "critical wetting distance" and "wetting coefficient" were proposed. The linear relationship between wetting front movement distance and cumulative infiltration amount was confirmed. Spatial distribution model of soil moisture and its simple derivation method were established.

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.
