ABSTRACT The study on experiment and theory on Adsorption and Desorption of Light Paraffinic Hydrocarbons in Real Reservoir Cores at High Temperature and High Pressure is a theme which is of difficult, but of practical and theoretical values, and which also is the foundation of the study on the laws of phase behavior and percolation of gas condensate system in porous media.

Furthermore, it was found that, when the ferromagnetic phase fraction is above the percolative threshold, the metal-insulator transition temperature increases, the resistivity decreases, but no obvious changes appears in the magnetoresistance value with increasing the ferromagnetic phase fraction.

最后，我们研究了两相比例对金属—绝缘体转变温度和磁电阻效应的影响，发现在渗流阈值以上，增加铁磁相含量可以提高金属—绝缘体转变温度，降低系统的电阻率，但对磁电阻数值没有明显的影响。

FEMOL is systematically applied to various moving boundary problems, including: membranes contact with rigid foundation, shape optimization of cross-sections of elastic torsional bar, seepage through a dam with a free surface, Mindlin-Reissner plates contact with rigid foundation, free Mindlin-Reissner plates on tensionless

Most removal of chemical and microbiological constituents occurs in the top 2 m of the vadose zone, biological breakdown of organics, nitrification, and denitrification occur in the unsaturated zone and in the aquifer.

大部分的用化学和微生物去除发生在最上层两米的渗流区域。生物学的有机分解，硝化和反硝化作用则发生在未饱和区域和含水层。

Soil Vapor Extraction is a common method of removing VOCs from the vadose, or unsaturated zone, which is the area between the ground surface and the water table.

土壤的蒸汽抽提技术常用于从渗流层或水不饱和层（指处于地平面与地下水位线之间的土壤区域）的土壤中脱除可挥发性有机物。

The research method and principle for vadose field of confined deep water are also discussed, and the waterhead contour and hydrodynamic zoning maps are outlined for the study interval, by which flow regimes and rules of deep water are revealed in the depression.

在阐述区域地质构造和含水系统划分的基础上，论证了川西坳陷上三叠统含水系统隶属于沉积水压系统类型，提出了研究深层水渗流场的原则和方法，并根据计算勾画了研究层水头等值线图和水动力分带图，揭示了深层水的流动特点和规律

Under intense erosion condition,soilmoisture wavily changes with increasing of slope length.
