If get encountered cliff body Zai,enough nature is had inside narrow geometrical dividing line osmotic, cai heats up craft but can use the affusion that is similar to oil to extract place is used or vapour drive oil into ripe method.

如果钻遇的岩体在有限的几何界限内具有足够的自然渗透性，采热工艺就可能采用类似于石油开采所采用的注水或蒸汽驱油的成熟方法。

Based on the analysis on brachiopod fossils of the late middle Permian,the brachiopod extinction in Pre-Lopingian event of late middle Permian in this area can be divided into two sub screens: the first screen in the end of earlier Wushisanti Subage a...

通过川渝地区中二叠世晚期的腕足动物化石资料的研究，表明本地区中二叠世晚期的乐平世事件中腕足动物的灭绝可划分为前后2个不同的次级幕：早期的五十三梯亚期之末的第一幕和晚期的倒钻岩亚期之末的第二幕，且第二幕的灭绝规模要比第一幕更大。

Based on the analysis on brachiopod fossils of the late middle Permian, the brachiopod extinction in The Lopingian event of late middle Permian in this area can he divided into two sub screens: the first screen in the end of earlier Wushisanti Subage and the second screen in the end of later Daozuanyan Subage. The second screen's extinct scope is larger than the first screen's.

Drilling and mucking is the way that gold is taken from the ground. A mucker is a machine that gets the rock out of the ground and moves broken rock onto a conveyor belt. A hand mucker is a man who shovels ore and unwanted rock out of a mine.

钻岩及除渣是将黄金自地面挖出来的方式，除渣机是一台机器，负责挖出地下的石头，并将这些碎石运送至输送带上，而手动除渣则是指工人由开挖矿砂及不要的石头。

A total of 614 sediment samples at an interval of about 1.5 m from all 5 sites of the Integrated Ocean Drilling Program Expedition 311 on Cascadia Margin, northwestern Pacific were analyzed using a Beckman Coulter LS230 Particle Analyzer. The grainsize data were then plotted against depth and compared with other potential proxies of gas hydrateoccurrence such as soupy/mousselike fabrics in sedimentary textures, gas hydrate concentration derived from LWD data using Archie's relation, IR core images and the recovered samples of gas hydratebearing sediments.

对取自IODP 311航次（东北太平洋Cascadia大陆边缘）所有5个站位、采样间距约为1.5 m的614件沉积物样品，利用Beckman Coulter LS230激光粒度仪进行了沉积物粒度分析，获得了沉积物粒度随深度变化特征，进而与水合物层位的替代指标进行了位置对比，这些指标包括特殊沉积构造（soupy和mousselike构造）、测井数据推算出来的水合物饱和度、岩芯红外图像和实际钻取的含水合物沉积物等。

Pneumatic hammer drilling technology with low wob,low rate of revolution and high capacity to break rock is one of the best effective methods to solve the problems of hard rock drilling.It includes air drilling and rotary drilling technology,so its penetration rate is usually two or three times higher than rotary drilling.

空气锤钻井是一种低钻压、低转速、高冲击破岩回转钻进技术，它兼容了气体钻井和冲击回转钻井的优势，其机械钻速一般比回转钻井高，是当今解决硬岩钻井难题的一种有效方法。

It was considered that the control of the PRD fluid performance and the dosage of flow pattern adjusting agent PF-VIS were the key of the technique. The viscosity of PRD spudding fluid increased rapidly with the decrease of shearing rate, it indicated that it had good sand carrying ability. The spudding fluid was good capacity of high temperature stability under the low shearing rate, its viscosity was much higher than that of traditional drilling fluid, it was beneficial for cutting carrying in big deviated wells and preventing the formation of cutting bed.

认为要控制好PRD弱凝胶钻开液的性能，流型调节剂PF-VIS的加量是关键；PRD弱凝胶钻开液的粘度随着剪切速率的降低而急剧上升，显示了其优良的井壁携砂带砂性能；PRD弱凝胶钻开液体系具有较好的高温稳定性；PRD弱凝胶钻开液体系在低剪切速率的高粘度，大大高于传统聚合物钻井液，有利于在大斜度井携带岩屑以及防止岩屑床的形成。

During air drilling,under the precondition of high drilling speed, pneumatic hammer drilling technology can validly control the well deflection.

In regard of the problems of large holes to be bored, deep boring into rock and complicated rock layers in construction of bored pile foundations of in\|water piers of main spans of Wuhu Changjiang River Bridge, selection and structural features of cutter heads and hobs of the boring equipment used are described.

针对芜湖长江大桥正桥水中墩钻孔桩基础施工中存在的孔径大、钻岩深、岩层复杂等问题，阐述钻孔设备中刀盘和刀具的选用要求及结构特征。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
