Second, transient flow for vertical well and fractural well in porous media with arealanisotropy has been researched in this paper. The analytic solution for vertical well andsemi-analytic solution for vertical fractural well is developed by using image inversion,superposition principle, Laplace transformation, Fourier transformation, as well as theirinverse transforms, and storage and skin are taken into account. For vertical fractural well,influence of pressure and productivity is studied when the orientation of artificial fractureisn't in accordance with the direction of major permeability, it is fundamental to evaluatepotential and analyze well test data.

In order to analyze rheological property and establish constitutive model of Q_2 loess, a series of uniaxial creep experiments on different water content are done .The creep test curves and stress-strain isochronism curves are drawed with the result of experiments and conclusions are reached from the curves. The creep performance of Q_2 loess is different under the different stress level. In the different time the stress-strain isochronism curve has obvious inflection point namely yield stress and the yield stress reduces along with the increase of water content, which can be described by exponential function.
为了分析黄土的流变特性和建立相应的本构模型,本文首先根据对不同含水量的Q_2黄土进行的一系列单轴应力条件的室内蠕变试验结果,分析总结了Q_2黄土蠕变特征和应力—应变等时曲线特征,得出Q_2黄土在不同的应力水平下蠕变变形表现形式不同;在不同的时刻应力—应变等时曲线存在有较明显的拐点,拐点所对应的应力即为屈服应力,屈服应力随着含水量的增大而呈指数形式降低;Q_2黄土可近似看成一种线性粘弹塑性体。

Hydrostatic transmission is widely used in construction machine. The research of one of its hard cores, low speed high torque radial piston motor, is very important. To directly estimate the life of this kind of motor, and to design a orbit curve with the longest life at same condition, this paper gives theoretic research of the equal contact stress inner curve of radial piston motor. The research is divided into four parts:1 Taken all forces the piston endured into consideration when radial piston motor working, the force between roller and orbit is deduced.

The results showed that the diurnal changes of photosynthesis of S. chinensis in tile overstory took on "double-peak" curve with remarkable midday depression. The midday depression was mainly due to non-stomata1 limitations. On the contrary, the diurnal changes of photosynthesis of S. chinensis in the understory took on "one-peak" curve with low Pn. The maximal Pn was only half of that of S. chinensis in the overstory. The correlation analysis showed that the limiting factor for this low Pn might be light intensity (p=0.001). Compared with its accompanying plants, S. chinensis was in a disadvantaged status in the community with low photosynthetic capacity, water use efficiency, and the ratio of photosynthetic rate to respiration rate.
结果表明:夏蜡梅冠层的光合速率日进程呈"双峰"曲线,有明显的"午休"现象,经分析其"午休"的原因主要是由非气孔因素引起的;林下夏蜡梅则表现为"单峰"曲线,净光合速率较低,最大净光合速率不及冠层的1/2,相关分析结果表明其最重要的影响因子是光合有效辐射(p=0.001);与其它伴生植物相比,夏蜡梅的日均光合速率、最大光合速率、水分利用效率和光合速率/呼吸速率都明显偏低,在群落竞争中处于不利地位。
