岩石

They are made of continental rather than oceanic rock, and seem to be a small part of the jigsaw puzzle of continental drift rather than genuine oceanic islands.

它们是由大陆岩石而非海洋岩石构成的，似乎更像是大陆漂移七巧板的一小部分，而不真正的海洋岛屿。

The deformation characteristics of granite under constant amplitude cyclic loading were studied with multi-function apparatus RMT-150B.

摘 要：利用RMT-150B岩石力学多功能试验机，对花岗岩进行常幅循环加载试验，研究循环加载过程中岩石的变形特性。

The intermediate-basic volcanic rocks with SiO2 content less than 57.48 wt% are high in Al2O3(20.22-16.34 wt%) and K2O, enriched in large ion lithophile elements, show obvious Nb, Ta negative anomaly, these are same to the basalts which formed in island arc. The andesite, dacite and rhyolite rocks with SiO2 content between 62.11-75.19 wt%, are similar with the I-type granitic rocks formed in island arc in their geochemistry. It is suggested that the Jueluotage area of East Tianshan was in island arc setting during Late Carboniferous, when the subduction of the ancient Asian Ocean was in progress.

其中w(SiO2)小于57.48%的中基性火山岩具有高w(Al2O3)(16.34%~20.22%)，较富钾，富集大离子亲石元素，具明显的Nb、Ta负异常；w(SiO2)介于62.11%~75.19%之间的安山岩、英安岩和流纹岩岩石化学特征与准铝质的Ⅰ型花岗质岩石相似，其地球化学特征也反映出岛弧花岗岩的特点，表明东天山觉罗塔格地区路白山一带在晚石炭世仍处于古亚洲洋向南俯冲的岛弧环境。

The mechanical causes of formation of joints can be judged by deflexion coefficient and/or the root of mean square of height of joint surfaces.

介绍了检验和分离岩石表面形貌中波纹度的方法，并研究了岩石表面形貌的波纹度特征。

Because fluid pressure and rock stress change during sealed coring process, the degasification and rock pore volume change. As a result, there is difference between laboratory measuring saturation with in-situ saturation. Therefore the laboratory measuring fluid saturation has to be corrected to predict the in-situ fluid saturation.

在密闭取心过程中，由于流体压力和岩石应力的改变，导致流体脱气和岩石孔隙度改变，因此室内测定的岩心含水饱和度和实际油藏含水饱和度存在较大的误差，有必要将室内测定的含水饱和度校正到油藏条件下。

The nonlinear phenomena in above experiments can be explained by probability density distribution of micro-cracks.

用岩石样品在恒定压力下的蠕变实验，得到岩石的蠕变曲线。

I was looking to paint more of a rocky desert landscape which allowed me the opportunity to reflect some of the sky tone on the rocky planes.

我希望把沙漠景象表现成多岩石的，这样我可以在岩石表面画上些反射的天空的色调。

Then the finite element software ANSYS is used to simulate the orthotropic flattened Brazilian disc specimen subjected to diametrical compression, the accuracy of the approximate formula of compression displacement is checked. The formula is further modified with a semi-empirical and semi-analytical approach, and it is shown to have better accuracy than the original formula covering the whole range of orthotropic anisotropic index of rock, the error is less than 6%.

用有限元分析软件ANSYS模拟正交异性岩石的巴西圆盘试样的对径压缩实验；利用有限元分析结果对正交异性平台位移压缩公式进行精度检验，并用半经验半解析的方法，对该公式进行局部的修改，修改后的公式在岩石材料的正交异性指数的整个范围的总体评价上，误差小于6%，具有更好的计算精度。

So, here is a good example of a rock, a sedimentary rock but with a white dike.

因此， 这个岩石就是个很好的例子，一个上面有白色岩脉，由沉殿物所生成的岩石。
