On the basis of accurately calculating the parameters of formation water,the effects of these parameters on the effective porosities of rocks and the parameters of identifying gas reservoirs are emphatically analyzed.It is pointed out that in the strata containing salt-water,if the parameter values of pure water are used,the calculated effective porosities of the rocks and the calculated parameter values of identifying gas reservoir will be all reduced,which exerts a serious influence on the log recognition of gas reservoirs.

在准确计算地层水参数的基础上，着重分析这些参数对地层岩石有效孔隙度和气藏判识参数的影响，指出在含盐水的地层中，如果采用淡水参数值，其结果是使计算的岩石有效孔隙度和气藏识别参数值降低，严重地影响了气藏的测井识别。

But the real focus of shoring in hard rock, the rock Zaocheng a trapezoidal shape of right-angle look, and then insert-beam, and right-angle ladder to fully close some acute angle, using principles of mechanics into a half-beam as the base.

而真正的重心撑在坚硬岩石里，岩石凿成了形似直角梯形的样子，然后插入飞梁，使其与直角梯形锐角部分充分接近，利用力学原理半插飞梁为基。

Rock land mountain,desert and soil mountain are widely distributed in the middle and upper reaches of Yellow River basin.

黄河黑山峡地区地形复杂，加之裸土、沙漠和岩石光谱的相似性与复杂性，使遥感技术在该地区的应用受到限制，但是由于地形起伏、岩石风化及表面粗糙度等因素的影响，石质山地纹理明显。

RFPA is used to study the failure process of rock specimens under static and dynamic loadings.

1引言岩石在动态载荷作用下的变形与破坏过程对于岩石破碎等与工程密切相关问题的研究具有重要的作用。

The petrological study and studies in element and isotopic geochemistry indicate that the pluton belongs to high-potassium calc-alkaline I-type granite, whose magma came from basic basalt in the thicken crust bottom by partial melting, and are of syn-collisional features. The pluton provides a direct petrological evidence of the plate collision and amalgalation.

岩石学、元素和同位素地球化学研究表明，岩体属于高钾钙碱性Ⅰ型花岗岩，岩浆来源于加厚地壳底部基性玄武质岩石的部分熔融作用，属同碰撞型花岗岩，是板块碰撞拼合的直接岩浆岩证据。

The form of this chair comes from rock in nature. The irregular form is realized through laminating of many layers of board material. The logic of laminating has nothing to do with the mechanism of real rock generation.

椅子的形式来源于自然当中的形式——岩石，不规则的形体用分片层叠的方法来实现，这种层叠的逻辑与真实的岩石生成的机理显然并无关系。

Selecting two ophiolite zones (namely Hongliugou-Lapeiquan ophiolite zone and Sulamutage ophiolite zone) respectively located within the southern and northern part of the Altyn fault and based on analysis of field geology characteristics and geochemistry, this paper recognized the rock types (mainly mafic and ultramafic rocks) within the melanges and subdivided each lithological unit based on tectonic environment.

本文以阿尔金断裂带南、北两条蛇绿混杂带(即红柳沟-拉配泉带和茫崖-苏拉木塔格带)为研究对象，根据野外地质特征和地球化学分析，鉴定混杂堆积的岩石种类，以构造环境划分各岩石单元，最后用大地构造相研究方法恢复阿尔金地区古构造格局，以碰撞造山带理论讨论其古构造演化。

During the development, simple microlites are turning to complicated ones, and they serve as the starthing point from which various forms of skeletal crystals grow.

通过大量工艺岩石学和实验岩石学工作，作者认为在发育过程中先是由简单的微晶成长为复杂的微晶，然后更长成为多种多样的骸晶，最后长成为完整晶体。

Its rock types are more complicated, which include siliceous rocks、mudstones、clastic rocks、carbonate rocks and transitional rock types between them.

岩石类型也很复杂，包括硅质岩、泥岩、碎屑岩、碳酸盐岩及其过渡类型的岩石。

And Pharaoh spoke to Joseph, saying, Your father and your brothers have come to you.

47：5 法老对约瑟说，你父亲和你弟兄们到你这里来了。

Additionally, the approximate flattening of surface strip using lines linking midpoints on perpendicular lines between geodesic curves and the unconditional extreme value method are discussed.

提出了用测地线方程、曲面上两点间短程线来计算膜结构曲面测地线的方法，同时，采用测地线间垂线的中点连线和用无约束极值法进行空间条状曲面近似展开的分析。
