Results In vitro recovery of the probe was mainly influenced by the perfusion rate. When the perfusion rate was set at 1.0μL/min, in vitro and in vivo recoveries of the probe were 50.16±2.34% and 14.096±0.58%, respectively. The enhancement indexes for 3%, 5% mentha oil were 3.8 and 17.6, respectively. The enhancement indexes were 9.2 and 24.8, for 3% and 5% of Azone, respectively. Conclusion The steady sate flux of meloxicam in rats is significantly improved by enhancer mentha oil and azone.

结果： 在实验条件下微渗析探针的体外回收率主要受灌注液流速的影响，为（50.16±2.34）%；反向渗析法测得探针的在体回收率为（14.096±0.58）%；MO的体积分数为3%和5%时，增渗倍数分别为3.8，17.6；azone的体积分数为3%和5%，增渗倍数分别为9.2，24.8；结论：不同体积分数的MO和azone均可显著增加美洛昔康经皮渗透稳态流量，azone的体积分数为5%时，大鼠角质层的屏障作用可能受到了较大程度的破坏。

Using the survey data of several indexes as well as field experimental data of soil hydrology of microbiotic crusts in artificial vegetation-fixed sand dunes in Shapotou area, the impacts of microbiotic crusts on soil hydrological processes which included the penetration, interception and evaporation processes of precipitation were examined, and their mechanisms were also studied. The security problem of vegetation-fixing system due to the changed soil water environment in fixed sand dune area was analyzed further.

本文在上面的立意下，我们对沙坡头人工植被固沙区对微生物结皮的若干指标进行了详细的调查和试验，并安排了一系列微生物结皮土壤水文过程试验，从不同的角度揭示了微生物结皮在降雨渗透、拦截和蒸发过程中的作用，及其对降水在沙丘土壤剖面中的水分分配过程和格局的影响，并进一步分析了微生物结皮对固沙区土壤水环境的影响和植被固沙体系的安全问题。

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。

Various log and core data are used to estimate the petrophysical parameters such as porosity and permeability, and to define the distribution and petrophysical properties of the framework sandbodies in each formations of the PermoCarboniferous in the Bohai Bay basin.

应用录井、测井及岩心资料，测定了孔隙度、渗透率等物性参数，查明了渤海湾盆地石炭-二叠系各地层组的骨架砂岩展布特征及其物性特征；应用相比法编图对渤海湾盆地石炭纪、二叠纪岩相古地理进行了恢复，研究了沉积相对储层及其物性特征的控制作用。

Unlike GCI, it takes more elusive forms in the specific context saliently represented by the prior utterance, and its inference is a multiplex combination of relevance, abductive and default reasoning, utterance context and rhetorical relations.

但与一般会话含义不同的是，特殊会话含义的具体表现形式灵活多样，对具体语境特别是先前语句的依赖性很强。而在推理机制上，关联、溯因推理、缺省推理、语句语境和话际关系等因素则共同作用，相互渗透。

The effect of Markov chain models in reservoir modeling is much concerned recently, but models are usually applied to simulating categorical attributes, such as lithofacies, sedimentary facies and subfacies, and very few to continuous attributes, such as porosity, permeability and oil saturation.

Markov链模型在储层随机建模中的作用越来越受到关注，但其多用于类型属性(岩相、沉积相、沉积亚相等)的模拟，对于连续型属性(孔隙度、渗透率、含油气饱和度等)的模拟还比较困难。

As the difference of solution characters for different mineral components in calcium thenardite, the solution and pervasion mutual actions can be found in the calcium thenardite rock salt body under the action of certain osmotic pressure.

溶解是盐类矿物的基本特性，渗透是流体在溶质浓度梯度、压力梯度及二者共同作用下经过多孔介质的运动。

The resistance factor of gas and liquid commingled injection grows with the injection rates rising while that of gas and liquid alternative injection wavily rises with the injection rates rising,however both the methods ca.

封堵调剖实验表明，泡沫复合驱具有优良的封堵调剖能力，其封堵能力随渗透率增加而增大；气液共注时，阻力因子随注入量增加而持续增大，交替式注入时，阻力因子随注入量的增加波动上升，但随着注入量不断增加，两种方式均能产生较好的封堵效果；低气液比交替注入时，封堵作用表现缓慢；大段塞交替注入时，封堵效果相对较弱。

Aimed at the complexity of fluvial strata, such measures as well cyclical comparison, step control and geological analysis of reference beds have been applied. Moreover the paper has developed a set of methods the techniques to extract the parameters controlling the formation of intra-sandbody thin interbeds. The present study has examined how thin interbeds affect the frame property and heterogeneity of individual sandbodies; revealed the permeability space distribution mode of meandering distributary channel's single side lithosomic body and straight distributary channel's aggrading lithosomic body. Through applying the distributary channel sandbody structural unit classifying and identifying method achievement, some horizontal wells have been deployed to dig the residual oil in the top of hick pay zone in the xing8-9 area, which shows better effect after they have been put into production.

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
