水平地层

At present, there are many diagnostic model of the evaporation duct, such as P-J model, MGB model, NPS model and Babin model etc. They are based on Monin-Obukhov similar theory, just it is different that confirms the flux and character scale in the surface layer. These models are only applied for the normality and homosphere in open sea without considering the alongshore effect.

目前国内外蒸发波导诊断模式有P-J模式、MGB模式、NPS模式、Babin模式等，但其基本原理都是依赖Monin-Obukhov相似理论，只是用于确定近地层通量的和特征尺度的方法不同，且仅适用于定常和水平均匀的开阔海域，并没有考虑到蒸发波导的近岸效应。

A rock mass of large horizontal extent bounded, especially above, by physically different material.

A rock mass of large horizontal extent bounded, especially above, by ''.'physically'.''''.

地层一个水平的大岩石区域，特别是在它的上面邻接的是''。

Subjected to actual measure method and technical level, it is difficult to predict the distribution of sedimentary facies of underground strata by rule and line.

限于目前的测量手段和技术水平，要做好地下地层沉积相的预测是很难的。

It has been caused much attention by many geologists at home and abroad. Based on the rich dinosaur resources in Henan Province, the author has obtained some important results through the scientific study and protection research of dinosaurs and,these results can help to discover more and more complete dinosaurs and other vertebrate fossils, to promote and raises the research level on the systematic paleontology and dinosaurs in Henan Province, and thus provides important scientific data on stratigraphy, paleogeography and paleoenvironment of Mesozoic basins, which can accelerate to build protection system at all levels and geological parks, all these can bring about a great advance in environment protection, tourism economy, agriculture, industrial production and social civilization.

以河南丰富的恐龙化石资源为依托，通过对恐龙化石的调查、发掘，科学特征和保护研究，不仅可获得一批重要的科研成果，促使发现更多更完整的恐龙化石和其它脊椎动物化石，促进和提升河南省恐龙研究水平，为中新生代盆地地层学和古地理、古环境研究提供重要的科学素材，而且可促进地质遗迹保护和地质公园建设，带动生态环境保护、旅游经济等方面的发展，达到促进地区经济效益增长和社会进步之目的。

Along with horizon development well to implement, some problem became more and more gravity, such as sandbody'scale and sandbody'boundary was uncertainty and layer pressure was uneqilibrium for different well area development degree is not community. These taked a few difficulty of comprehensive evaluaterating, deploying horizon development well, adjusting well trackway for the gas field, and it might take any geologic risk.

随着该气田水平开发井的逐步实施，其含气砂体规模及砂体边界的不确定性以及由于各井块开发程度的不均一性而导致的地层压力不均衡等地质难题都日益显现出来，这些都给该气田的全面评价、水平开发井部署和井轨迹的调整带来困难，并可能引起更大的勘探开发风险。

Due to the first try of the kind in China,both sidetracking window milling and orientation were challenging,which were affected by horizontal window,formations,friction,and operational parameters.

由于在水平段套管内侧钻尚属首次，开窗及定向均比较困难，受水平窗口、地层、摩阻、施工参数影响，弯螺杆前面的钻头方向不断处于变化之中，导致钻出的井眼呈多台阶形状，进而使实施过程中的起下钻摩擦阻力明显增加。

The ZOOMLION KSD25 Dry-Wet Horizontally directional Drill is the first drill which drills through hard rock without a bentonite and mud pump. Its pneumatic percussive technology has not only solved the problem of mud pollution, but also has increased its efficiency 40% higher than a normal drill. Additionally, its cost is also much lower, and therefore, it has been considered as a most efficient solution for complicated stratum (including pebble and gravel, backfill and rock).

中联KSD25干湿两用水平定向钻孔机是我国第一台不使用膨润土和泥浆马达就能在硬岩中钻进并导向的钻机，其国际领先的气动冲击钻机技术不但不存在泥浆污染的问题，而且效率比普通钻机提高40％以上，成本也要低廉得多，被公认为目前对付复杂地层（包括卵砾石、回填土和岩石地层）最为有效的方法。2 s# C J， k5 _% C

As the field work in Xi Shanping Tunnel showing, constructing tunnel in flat dip coal-bearing strata, if there is thick-bedded hard rock nearby, the stability of the wall rock is ensured by the control in soft rock supporting reinforce.

本文对近水平煤系地层中修筑隧道的围岩稳定性进行了深入分析，在含煤岩的围岩变形及应力重分布规律的研究上有所创新，为近水平围岩的支护设计优化提供了可靠依据。

The frequency-dependent sensitivity coefficients with respect to the parameters of the radial layers are computed quantitatively. Comparing the horizontal permeability with the vertical permeability, the horizontal mobility plays the predominant role over the entire frequency range. The Stoneley wave is more sensitive to the velocity of the horizontally propagating SH wave than the flexural wave.

利用灵敏度曲线定量研究了不同频率下地层各个参数对相速度和衰减系数的贡献大小，主要结果显示模式波的衰减受水平渗透率影响明显，而垂直渗透率的变化对模式波几乎无影响；斯通利波对水平向传播的横波速度比弯曲波的灵敏度高。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
