对工程区右岸地下引水洞室群的围岩稳定性进行系统研究，可以控制工程投资，提高施工质量和支护设计精度；分析评价洞室围岩的整体及局部稳定性，消除洞室稳定的潜在危害，对保证地下洞室的施工安全、围岩的长期稳定以及优化设计具有十分重大的工程实践意义。

The δ〓O for both of them are changed due to water/rock interaction at water/rock weight ratios of larger than 0.1, and the calculation indicates that, in this case, the influence of water/rock interaction on the δD value of the fluid is minor. In the upper part of the geothermal system, the upward ore forming fluid mixes with low temperature groundwater with very low salinity and δ〓O, which may cause the precipitation of metals.

根据氢、氧同位素研究结果，嵩溪银锑矿床的上升成矿流体是由岩浆热液与循环地下水热液混合而成，这种混合成因含矿热液上升到地热系统上部与低矿化度、低δ〓O的低温地下水发生了不均匀混合，这种混合作用导致金属矿物沉淀，但成矿物质是由上升成矿流体带来的。

This paper examines the cracks appeared in the retaining wall beside the FeiYuze tunnel uplink secondary lining vault. The seismic CT technology was used to investigate the engineering geology structure of the covering rock mass above the tunnel. The results indicate that the rock mass had three fracture zones along tunnel axial and the rock mass quality in the small mileage entrance section was poor.

针对飞鱼泽隧道的上行线二衬拱顶靠档墙处出现裂缝，经地震CT技术查清隧道上所覆盖岩体的工程地质结构结果表明，沿隧道轴向存在三个岩体破碎带，其中在小里程入口段，岩体完整性较差。

You can also use the rock and cord technique where you place a 1.5 rock under the two tarp layer and then squize the tapes into a narrow neck around the rock and tie this tight with a cord.

您也可以使用岩石和脊髓技术，您一个1.5 岩下的两个篷布层，然后squize到磁带一个狭窄的颈部周围的岩石和领带这个紧凑的脊髓。

In flat dip layer, the seam thickness control the stability of the wall rock, the thick-bedded hard rock is stable than the thin-bedded hard rock.

岩层厚度在缓倾斜时对围岩稳定起控制作用，厚层硬岩整体稳定性好于薄层状硬岩。

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。

Concept To describe changes in the relative configuration of rocks, imagine that there is a unit sphere, 1 in radius, in the rock before it is deformed. When the rock is deformed homogeneously, the sphere becomes an ellipsoid. Then this ellipsoid is called strain ellipsoid, whose shape and orientationrepresents the rock's strain condition.

概念 为了形象地描述岩石的应变形态，设想在变形前岩石内有一个半径为1的单位球体、平均变形后成为一个椭球，以这个椭球形态和方位表示岩石应变状态这个椭球称应变椭球。

In a society which revolves around rock-paper-scissors for decision making where scissors is generally accepted as the most successful, the one person that uses rock will dominate. In warcraft balance, strategies have a very similar relationship to each other as does the rock, the paper and the scissors.

在一个只靠剪刀，石头，布做出胜负决定的社会中，当剪刀被多数人公认为是成功的选择时，少数几个会出石头的人就会通知这个胜负世界。

The company has strong product development strength, internal combustion series of rock-drilling machine, electric drilling machine, pneumatic rock drill, electric rock drilling, rice and wheat combine harvesters and so is my company's independent development.

公司有较强的产品研发实力，系列内燃凿岩机、电动凿岩机、气动凿岩机、电动岩石钻、稻麦联合收割机等均是我公司自主开发的。

This method has the shortages of large calculation work and low comprehensive function. According to the basic rock-crushing theory, a computation model and an evaluation method for rock-crushing efficiency based on the crushing work ratio were provided by analyzing the energy consumption of rock crushing with roller bit.

根据岩石破碎的基本理论，对牙轮钻头破碎岩石所消耗的能量进行分析，建立了岩石破碎比功的计算模型，并提出一种基于破碎比功的岩石破碎效率评价方法。

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.
