By using grand canonical ensemble Monte Carlo method, machanism for the adsorption of methane in single wall carbon nanotubes at 74.05 K has been investigated. It is found that the adsorption of methane in smaller SWNTs, whose diameters are 1.22nm and 1.632nm, exhibits "pore filling" behavior. In contrast, for the SWNTs of diameter larger than 2.04nm, capillary condesation takes place.

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 result indicates the t-BHP or diamide both cause the mass loss about the membrane protein thiol in hepatocytes, the fast oxidization about glutathione in hepatocytes, the leakage of lactate dehydrodenase, but the level of t-BHP is larger than of diamide. In the aspect of lipid peroxidation, only the t-BHP produces apparent change. As to actin and tubulin, they both find fall-off and present time-dependency effects. The result in Confocal fluorescent microscope also show these two cytoskeletal proteins are related to cell blebbing, but they don''t play the same role during the porcess. Tubulin may be more important than actin. If the study predispose dithiothreitol before adding t-BHP or diamide, then the damage by the diamide is repressed, but just partly protection for the damage by t-BHP.

结果显示t-BHP或diamide均可造成细胞膜蛋白硫醇大量流失与胞内GSH快速氧化，亦显著导致乳酸去氢□渗漏，但t-BHP诱发的渗漏程度大於diamide；在脂质过氧化方面，则仅t-BHP处理组产生明显的脂质氧化情形；至於肌动蛋白与管蛋白单体均可见减少且呈现时间依赖效应；在雷射共轭焦萤光显微镜观察中，亦显现这两种架构蛋白与细胞膜起泡有关，但两者在小泡生成的过程中扮演的角色并不完成相同，可能管蛋白较肌动蛋白重要；如果细胞在t-BHP或diamide加入前预先以dithiothreitol处理，则diamide 所造成的伤害显著的受到抑制，但DTT对t-BHP所诱发的伤害则仅有部分保护效果。

The main causes of the vibration in pipeline system are in two respects : The first is the vibrant force of the medium acted on pipeline system,i.e.exciting signal,such as the vibrant force caused by the gas flow at the compressor ′ s inlet and outlet and at the ramified and nodel points as well as the action of pig passing through pipeline bridge,etc.;The second is the response to the exciting signal,which is relating to the characteristics of the pipeline system,i.e.the rigidity,support,quality and equipments of the system besides the waveform of the exciting signal.

管道系统振动的原因主要有两方面，一是介质对管道系统产生的振动力，即激发信号，如气流在压缩机进、出口，分支节点部位产生的振动力，清管器通过管桥时对它的作用等；另一方面是对激发信号的响应，其响应除了和激发信号的波形有关外，还和管道系统本身的特征，即系统的刚度及支撑，质量及其配置等情况有关。
