At the super-low permeable reservior sandstone of Fu and Yang in Daqing Oilfield, many pore throats exist a lot in the types of compacted and restored flakes and curved lamellas while the pore volume of micropore and the thin, compacted and shrunken throat that contribute little to flow take large scale in the total pore space. Thereof high filtrational resistance is caused by much trouble including high content of reservoir shale, serious sensibility to pressure at waterflooding, remarkable effects of undersaturation and water blocks in micropore. A method with laboratory experiment, theoretical confirmation and field application included was adopted to analyze the non-linear flow characteristics, to reveal the deep mechanism of pinhole enveloping macropore and to provide a new technology of improving the development effect. The outcomes aquired are as follows: Multiple cores with different low and super-low permeability were selected to perform seepage experiments by gas, water and oil. Three fields of flow were observed in the reservoir at different low and super-low core permeability. They are pseudo- elastic flow, transition flow and plastic creep flow. So the concept that there was no correlation of rocky absolute permeability with fluid properties that pasted itself was broken up. Two-phase seepage of water displacing oil in uniform super-low permeability shows that the two-phase seepage zone is narrow.

针对大庆油田扶、杨特低渗透油层砂岩孔隙喉道的大小和形态以压实再生型片状、弯片状喉道分布较广，压实、缩小型细喉道型，微孔不可流动的孔隙体积所占总孔隙体积的比例较大的特点；及储层泥质含量高，注水开发中压力敏感性强、微孔隙欠饱和及水锁效应显著，导致流体渗流阻力增大的问题，本文采用室内实验、理论推证和矿场应用相结合的方法，研究、分析了流体非线性渗流特征，更深刻地揭示出小孔包围大孔的机理及产生原因，并提供了改善开发效果的新的技术方法，取得如下成果：选择不同渗透率的低渗透、特低渗透岩心，进行了气、水和油单相渗流实验，揭示出当岩心渗透率不同时，油层内的流体呈现出拟弹性流变、过渡流变、塑性蠕变三种流变区，从而打破了岩心的绝对渗透率与通过岩心流体性质无关的观点；同类特低渗透岩心的水驱油两相渗流实验表明，两相渗流区较窄。

This is enough to make Fantasia better as an album and a statement of purpose than Free Yourself, but no matter how good tracks like "Uneligible" sound - and with its fuzz-toned instrumental breaks and skeletal beats, this track does sound pretty great — it's hard not to wish that there were hooks as memorable as the production.

就这点已足以使Fantasia质量优于且目的强于前专辑Free Yourself。像&Uneligible&这样的歌如此地好听——它柔和的曲调，精粹的乐队演奏和独敲的鼓点——的确让该曲非比寻常——你很难不期望该制作不给你难忘的印象。

To solve the nonlinear attitude control problem of a class of spacecrafts, the strongly coupled dynamics model is decomposed into some subsystems and the coupling between the subsystems, unmodelled dynamics and exterior disturbances are regarded as the uncertainty of the system.

引 言空间飞行器的姿态控制系统是一个具有参数摄动和外来干扰的非线性系统。滑模控制(Slidingmode control，SMC)对系统参数的不确定性和干扰具有较强的鲁棒性[1，2 ] ，近来越来越多地被用于对空间飞行器的控制，但滑模控制的输出存在高频抖振。

The enhancement of the field emission ability is attributed to the fact that the field-induced screening effect can be effectively avoided due to the widely spaced intervals that exist between the unoriented nanowires.

It is very important to manage the enormous size of image databases and retrieve images we need. The drawbacks of traditional text-based image retrieval are that it is time consuming and labor consuming when labeling the keywords on the image, which often untruly represent the content of image.

传统的基于文本的图像检索的缺点通常是为图像加上关键字比较费时费力，常常不能准确地反映图像的内容，且带有很强的主观性，不同的人会有不同的理解，这已不能满足用户的迫切需求。
