Aiming at these problems, we have designed the processing workflow to effectively suppress the surface Wave interference, regular interference, high energy interference, and other random noise interference. The treatment clue was from thick to thin. Firstly, the spectral analysis method was used to establish macroscopic velocity field. Then, the ray tomography method was used to enhance the accuracy of velocity analysis and to establish a more accurate velocity model. Finally, the finite difference pre-stack depth migration on method in -k domain was adopted to solve the imaging problem of subsalt and salt dome flank.

通过合理组织处理流程，有效压制了面波干扰、规则于扰、强能量干扰和随机噪声干扰；采用由粗到细的思路，先利用谱分析方法建立宏现速度场，再利用射线层析成像方法提高速度分析精度，建立了较为准确的速度模型；利用频率－空间域有限差分叠前深度偏移解决了盐下及盐丘侧翼的成像问题。

And the key is to take advantage of the physical and chemical properties of shale or mud to enable the shale or mud to form a semipermeable membrane or form a high quality partition membrane on the wall of the well, so as to prevent the mud from flowing into the formation to effectively stabilize the wall of the well and protect the reservoir.

水基钻井液成膜技术是当今研究的热点，其核心技术是利用页岩或钻井液的物理、化学特性，使页岩或钻井液具有半透膜的性能或在井壁上形成一层较高质量的隔离膜，阻止钻井液向地层的进一步滤失，从而有效地稳定井壁和保护油气层。

By that time he had suffered four cases of stomach bleeding and his skin disease was so bad that no medicine had any effect. The only way to treat it was to "spray-paint" the medicine on layer by layer.

在那以前，他的胃已严重出血四次，可怕的皮肤病更是恶化成了药石罔效的顽疾，唯一的对治法，是在溃烂的部位「拷漆」，一层一层地把药涂盖上去。

The correlation of hydrocarbon accumulation and major control factors between these two basins indicates that there exist premium source rocks and reservoirs in subsalt carbonate rocks of Cambrian in these basins, and regionally distributing gypsum-salt rock of Middle Cambrian is good cap rock.

通过油气成藏要素及其主控因素的对比研究发现，塔里木盆地和东西伯利亚盆地在寒武系盐下都发育了优质的烃源岩和储集层，而区域性分布的中寒武统膏盐岩是良好的盖层。

The nuclei were clear and the cell was well-stacked. Double layer structure could be seen in part of areas, displayed as monostratal keratinocytes linked with string-like cells. Most of keratinocytes differentiated into double layers, and cells linked with others with cable-like structure. The nuclei still could be seen.

部分区域细胞出现双层结构，表现为单层的角质形成细胞上面铺有连接成条索状的细胞。3周的角质形成细胞大部分为双层结构，异层及同层细胞之间彼此衔接，呈索形结构，细胞核仍然清晰可见，细胞不如2周时饱满。4周的角质形成细胞部分区域为三层结构，且细胞较前变得萎缩，表现为细胞浆减少，细胞核变小。

On basis of diagenetic temperature research, combining with burial history and geothermal evolution, the author has found out the time when major diagenesis influence reservoir quality happened.

In cross-sectioned root form 2 middle bark layer next Internal bark layer especial structure of regularly array; epidermis cell of stems and leaves have developed thickened epiderm, leaves epidermis covers hair, it formed developed vascular bundles.(4)Chromosomes of Agropyron cristatum is tetraploid .

根横切面上形成了在紧靠内皮层的两层中皮层细胞有规则整齐排列成两环的特殊结构；茎和叶表皮细胞均具有发达的角质层，叶表皮多密被毛，其形成了发达的维管束及维管束鞘。

The magnetite with a mean diameter of 8nm was prepared by chemical coprecipitation methods. By the addition of nonionized oleic acid to the suspension of magnetite in solution during precipitation, the magnetite nanoparticles were coated with a double surfactant layer. A gel-like precipitated precursor is then formed because of the hydrophobic interaction among those coated units. By transferring of this precursor to an organic solvent, the surfactant double layer on Fe〓O〓 nanoparticles reduces to one; however, it still remains as a double layer by transferring to an alkaline aqueous solution. Both these cases give in stable colloids of superparamagnetic Fe〓O〓 nanoparticles.

从解决无机磁性Fe〓O〓颗粒与有机烯类单体的相容性入手，采用化学共沉淀法，制备了平均直径为8nm的超顺磁性Fe〓O〓颗粒，在制备过程中以非离子形式引入油酸，在Fe〓O〓颗粒表面形成一个具有双层结构的疏水外壳，并通过疏水相互作用凝聚成磁性Fe〓O〓凝胶，能够以单分子层结构形式溶解在非极性溶剂中，也能够以双分子层结构形式溶解在碱性水溶液中，形成稳定的超顺磁性Fe〓O〓溶胶。
