In this paper, the Iron-oxide-coated sand absorption character prepared in different temperatures was studied, mainly tested its absorb hexad chromium, and the inherent reason that formed this differences was explained.

本文研究了不同温度下制备的铁覆膜砂吸附性能的差异，对铁覆膜砂吸附Cr的性能进行了综合的测试，说明了形成这些差异的内在原因制备温度对IOCS的吸附性能有显著影响，一般低温制备的IOCS要比高温制备的铁覆膜砂吸附性容量较大，去除效率较高；覆盖在石英砂表面的铁氧化物在不同的焙烧温度下形成了不同的物质，110℃的低温一般形成FeOOH，而600℃高温下形成的则为α-Fe2O3。

Result shows that C/A is a sensitive factor for ASR expansion and more than one fixed C/A may be more suitable for identifying the alkali silica reactivity of aggregate in order to avoid the influence of the'pessimum effect'.

结果表明：胶砂比对检测集料ASR活性是一敏感因素，为避免"最不利现象"对检测结果的影响，采用多个胶砂比比采用一个固定的胶砂比更适宜。

After the termination of the model,kill the mouse,detect NPY and then see the content of NPY in the Hypothalamus of the mouse significantly lower.3.8g/kg(it is valid dose proved by pharmacodynamic experiment,about 9 times of human dose) of Shanzha Maiya granula and 13.6g/kg(15 times of human dose) of Decoction of Xiangsha six Mild Drugs can play a certain role in treating the animal model of child apositia resulting from leptin,fail to increase the animal\'s food-intake,but can increase its weight to some extent,Decoction of Xiangsha six Mild Drugs can increase the content of NPY in the Hypothalamus of the mouse.4.set up quality standard of qualitatively and quantitatively detecting Shanzha Maiya granula:detecting the content of aurantiamarin as a main component of Chenpi in Shanzha Maiya granula through the method of high performance liquid phase,qualitatively identifying Shanzha,Maiya,Chenpi through the method of plate chromatography.

造模结束处死大鼠，放射免疫法检测NPY，结果造模大鼠下丘脑NPY含量显著降低(正常组下丘脑NPY平均含量为22.2ng/ml，模型组下丘脑NPY平均含量为14.8ng/ml，P＜0.05)。3。山楂麦芽颗粒8g/kg(药效学实验有效剂量，临床用量的9倍)和香砂六君子汤13.6g/kg(临床用量的15倍)对侧脑室注射瘦素致厌食症大鼠有一定治疗作用，虽没有提高动物进食量，但在一定程度提高动物体重，其中香砂六君子汤能提高大鼠下丘脑NPY含量(模型组下丘脑NPY平均含量为14.8ng/mL，香砂六君子汤组NPY平均含量为20.3ng/mL，P＜0.05)。4。

The efficient sand body in the Sulige gas field, developed in relatively small size and ellipse or long ellipse shape, is always distributed isolatedly.

而苏里格气田有效砂体则以孤立状分布为主，砂体规模较小，形态呈椭圆或长椭圆状，当压力传播至砂体宽度边界之后，将不再满足纯径向流的渗流规律，目前推导的产能方程存在较大误差。

The Neopaleozoic reservoir in Tabamiao block is a typical lithological gas reservoir. The sand is thin and varies severely in lateral direction, and the velocity difference between sand and shale is little.

鄂尔多斯盆地伊陕斜坡北部塔巴庙工区上古生界储层是典型的岩性气藏，砂体薄，岩性横向变化快而大，地层砂，泥岩声波速度差异小，声波时差曲线对砂，泥岩的岩性反映不明显，储层预测难度大。

The medium-grained sandstones and medium-fine-grained sandstones form good reservoirs and the poststones medium reservoirs, while siltstones form poor reservoirs and pelitic siltstones poorest reservoirs. Sand bodies mostly develop in sand-flats, tidal channels and distributary channels of braided stream delta microfacies. The reservoir rocks of sand-flat and tidal channel are best with the physical property. Diagenesis such as compaction, cementation and dissolution has strongly reformed the reservoir rocks and the late dissolution has greatly improved their porosity and permeability.

中粒砂岩、中细粒砂岩属好储层，细粒砂岩属中等储层，粉细砂岩，粉砂岩属较差储层，而泥质粉砂岩则属差储层；砂坪、潮道和辫状河三角洲分流河道微相中的砂体最发育，它们决定了储集岩的发育、分布及原始物性条件；砂坪和潮道储集岩的物性最好，辫状河三角洲分流河道储集岩的物性次之，砂泥混合坪、辫状河三角洲分流河道间储集岩的物性较差；成岩作用对本区CⅠ油组的储层有强烈的改造作用，尤其是较晚期的溶蚀作用对岩石的储集性能有明显的改善，对本区CⅠ油组中孔高渗透储层的形成有很大的贡献。

It works by choosing appropriate gravel, scree, talus decries, coarse sand, medium sand, then ram them to be closely knitted. The sand gravel cushion can increase the bearing capacity of weak groundwork.

这种垫层法是用碎石、卵石、角砾、圆砾、砾砂、粗砂、中砂或石屑等坚硬、较粗粒径的回填材料，经合理级配并夯压密实后形成持力垫层，其主要目的是为了提高浅层软弱地基或不均匀地基的承载力。

Also, they study the planar distribution characteristics of the sedimentary microfacies so as to provide significant evidences for forecasting sandbody space distribution and 3-D reservoiring modeling.
