Based on the evaluation of rock mechanics properties of undrilling formation, a fuzzy optimization model for selecting the best similar layers with the same rock mechanics properties was established by applying theory of fuzzy optimization. Firstly the best similar layer located the undrilled area was chosen by the model. Secondly the performance of the bit used in the selected layer was evaluated by economic benefit index.

该方法在待钻地层岩石力学性质评价的基础上，首先应用模糊优选理论建立了地层岩石力学性质相似层位的模糊优选模型，用其进行相似层位的优选，然后应用经济效益指数法对相似层位的钻头性能进行评价，最后给出合理的钻头选型结果。

A series of rock loading experiments, including uniaxially compressing experiment, compressively-sheared fracturing experiment, bi-sheared faults friction sliding experiment and combined-fault activity experiment, are conducted by the utilization of thermal infrared imaging technology.

利用热红外成像技术，通过岩石单轴压缩、压剪、双剪摩擦滑移以及组合断层的双轴加载过程的红外观测实验，研究了岩石的两类应力活动以及典型构造活动的红外辐射规律。

In unmineralized rocks, the applied current is carried only by the ionic solutions on pore spaces and the resistivity is independent of the frequency of the current.

在未矿化岩石中，只有岩石孔隙内的液体携带电流而电阻率却不会取决于电流的频率。

It is considered that the Tertiary unconformity in Jiyang Depression can be divided into three types: typeⅠ1, typeⅠ2 and typeⅡ. Unconformity generally consists of weathered clay, semi-weathered rock and unweathered rock.

研究认为济阳坳陷第三系不整合可划分为三类：Ⅰ1型结构、Ⅰ2型结构和Ⅱ型结构，完整的不整合结构包括风化粘土层、半风化岩石、未风化岩石。

Rocks in these regions, known as Imdr Regio, Dione Regio and Themis Regio, were anomalously bright compared with their surroundings, suggesting that they were relatively young and unweathered by the corrosive Venusian environment.

这三个区域分别被称为&Imdr Regio&，&Dione Regio&和&Themis Regio&，这些区域的岩石相对于它们周围的岩石来说，亮度高的出奇，表明它们相当年轻，还没有被金星的腐蚀性环境所风化。

Their lithologic types are dominated by vitric tuff vitric crystal tuff and medium-fine tuffy sandstone and their genetic types mainly belong to complicated type of the airborne-water-carried and the airborne type.

研究了华北中部太原组含煤地层中火山事件层的岩石学识别标志和分布规律。研究结果表明：含煤地层中广泛发育火山事件层。火山事件层的岩石类型以玻屑凝灰岩、玻屑晶屑凝灰岩和凝灰质中细粒砂岩为主。

Combinds with several calculating ways of forming ages of rocks (Pb-Pb isochron way, inconsistent line model calculating way and three-stage model calculating way), a way to calculate element content of samples and forming ages of rocks was summarized.

本文主要是研究该法的计算，分析样品中元素量的计算，并结合几种岩石年龄方法（Pb-Pb等时线法、不一致线模式计算法、三阶段模式计算等）的计算，归纳总结出计算样品中元素量和岩石形成年龄的方法。

The contents of sand,shale or carbonate in complex formations can be obtained from logs of Elemental Capture Spectroscopy Sonde. The porosity and permeability calculated from the contents are comparatively better accordant to core data.

元素俘获谱测井利用定量测得的钙等多种元素的含量，计算岩石的碳酸盐岩含量，进而进行岩性识别和地层对比；利用ECS成果求出孔隙度、渗透率与岩心分析数据有较好的一致性；依据该岩石分类方法，做出单井的岩性剖面图，地层岩性的定性分析对比转化为岩性及其量化的对比划分。

These rocks cool in a short time, for they are expose d to the air and give off heat and harden rather quickly. The mineral grains that form during this fast cooling do not have much time and chance to grow.

由于熔岩喷出地表接触空气，热散发快，岩石冷却结晶的时问短，岩石中矿物晶体没有足够的时间和机会生长。

When rock collecting, you will soon find out that rocks can be categorized as one of three types.

当岩石收集，你很快就会发现，岩石可归类为三种类型之一。

She gently rebuff ed him, but agreed that they could be friends

她婉言拒绝了，但同意作为朋友相处。

If in the penal farm, you were sure to be criticized.

要是在劳改农场，你等着挨绳子吧！
