造成渗透的

In which the microorganism fouling was the main reason why the RO system operated and run diffidently, such as a great deal of sticky biofilm were attached to the surface of RO membrane, and which led to a higher influent press, a lot of energy consumption and lower water production and so on.

分析认为，RO膜污染主要来自无机物、胶体、有机物和微生物污染，其中微生物污染是造成反渗透水处理运行困难的重要原因，它会造成反渗透膜表面出现大量粘泥状生物膜，使进水水压过高，增大能耗，或造成膜的产水量下降。

Seepage deformation and other problems related with seepage are the main cause of danger in levee during the flood period.

渗透变形以及与渗透有关的问题是造成堤防在洪水期间险情的主要原因。

It put up no immobile shape ,have relative flowability , can intrude into the deep formation,selectively plug big pore pathor and high permeability formation,make the fluid turn to low permeability formation ,improve the low conformance factor caused by the nonhomogeneity ,improve the recovery ratio in big range .

它表现出没有一定形状，具有一定流动性，能进入地层深部，选择性地堵塞大孔道或高渗透层，使液流转向进入较低渗透层，改善因非均质性造成的波及系数低的问题，从而大幅度的提高油藏的采收率。

The drop of relative permeability of oil phase results in the.

由于产量递减主要是油相相对渗透率下降造成的，因此文中提出一种利用相对渗透率预测产量递减规律的新方法。

This covert appreciation of images in dangerous insofar as it accepts not a dialectical relation between political and formal meaning, not their nterpenetration, but a hazier, more reified relation, one in which topicality drops away as epochs fade, and the aesthetic aspect is, if anything, enhanced by the loss of specific reference (although there remains, perhaps, a cushioning backdrop of vague social sentiments limiting the 'mysteriousness' of the image) I would argue against the possibility of a nonidological aesthetic; any response to an image is inevitably rooted in social knowledge- specifically, in social understanding of cultural product.

l s1 o6 A8 l( R$ D7 E)|7 }$}迄今为止，这样的想法已经把对作品的鉴赏力引向了危险的境地，因为它接受的不是政治意义与正式意义之间的辨证关系，不是两者之间互相渗透的关系，而是一种更危险更实在的关系，其中最明显的就是随着几个重要时代的消褪而衰败，就美学角度来说，如果任何事物，因丢失具体的参考文献而被强调出来（尽管这些文献是存在的，可能一股当时社会含糊不请的氛围造成了缓冲力从而限制了作品的神秘性）我一定会反对一种叫非智慧美学的可能性，一幅作品的任何反应都必然植根于社会的知识形态，尤其是社会对文化产物的理解

Mylonitic coal may develop in the center of strongly deformational belt in pressing tectonic stress field. Since mylonitic coal is limited in a narrow area, biggish area in that tectonic coals of brittle deformation distribute is favorable for CBM exploration. Moat of areas are advantageous for formation of coalbed fractures and increase of permeability in extension stress field, but it is easy to beget dissipation of CBM and decrease of gas content. Therefore, study of structure of gas reservoir should be taken seriously.

研究表明，挤压应力场作用下，在强变形带的中心及其附近，可以形成糜棱煤类构造煤，但糜棱煤分布较为局限；在较大范围内形成脆性变形系列的构造煤，是煤层气勘采的有利区带；拉张构造应力场中，大部分区域内有利于煤层裂隙的形成和渗透率的提高，但易造成煤层气的散失，含气量降低，应重视有利的储气构造的研究。

To give you an idea of how the cuckoo wasp operates, imagine a ninja secretly penetrating a samurai's castle and causing complete carnage without ever being seen.

为了让你们如何杜鹃蜂经营理念，想象一个忍者秘密渗透日本武士的城堡，并造成完整的大屠杀而没有被人看见。

During the fracturing for low pressure and low permeability gas reservoirs, there are some main problems in conventional hydroxypropylguar - organic boron cross-linking system: Firstly, the water-lock damage to low pressure and low permeability gas formations by filter liquor; Secondly, the reason for alkali-sensitive damage in alkali-sensitive reservoirs is that conventional hydroxypropylguar - organic boron cross-linking fracturing fluids were cross-linked under alkaline environment, while the permeability of reservoirs is reduced greatly; Thirdly, the formation pressure is low, and the energy of flow back is not enough, at present, the main measure in oil fields is "injecting with liquid nitrogen", but this technique increased the cost of fracturing, making great troubles in operating, and leaving the liquid nitrogen also is a big problem.

在低压低渗透气藏的压裂改造过程中，常规羟丙基胍胶-有机硼交联压裂液体系存在的主要问题，一是压裂液滤液对低压低渗透气层造成的水锁损害；二是常规羟丙基胍胶-有机硼压裂液是在碱性条件下交联的，对碱敏性储层造成碱敏损害，降低储层渗流能力；三是地层压力低，压裂液返排能量不足，当前各油田采取的措施主要是&液氮伴注&技术，但是&液氮伴注&技术增加了压裂的费用，而且液氮存放也存在较大问题。

CO2 and H2S exist in the hydrocarbon zone and foramtion water,as the accompany gases of petroleum and nature gaso or components of formation water,which will cause corrostion to the cement sheath under certain conditions of humidity and pressure.It will decrease the cement sheath's alkalinity,which results in the decrease of cement sheath's strength,permeability increase,and places a premium on fluid channeling and borehole wall sloughs accident in plastic formation,shortening the oil- gas well's production lifetime and giving rise to tremendous ecomonic losses.

CO2和H2S作为石油和天然气的伴生气或地层水的组分存在于油气层或地层水中，在一定的湿度及压力条件下会对固井水泥环产生腐蚀作用，从而降低水泥环的碱性，使水泥环强度下降，渗透率增大，并诱发流体窜流、塑性地层井壁跨塌等事故，从而缩短油气井的生产寿命，造成巨大的经济损失。

Commonly dated material is organic matter, with the amount less than 2% in the sequence and affected by modern plant rootlets and agriculture, making younger 14C ages of all the organic materials but our laboratory can efficiently isolate young organic matter by adopting new pretreatment method.

最常用的测年物质是有机质，其含量低于2%，并受到农业施肥和现代植物根系渗透的影响，造成14C年龄偏年轻，本实验室采用新的前处理法能有效地分离年轻污染物。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.
