Anticlines are folds that arch upward, with older rocks in the center and younger rocks on the outside.

背斜褶皱认为是向上拱，与古老的岩石在中心和年轻的岩石在外面。

Other rocks are breccias — crushed and broken rock fragments, fused by the heat from impact collisions and ejected from the resulting crater.

其他岩石是角砾岩——由粉碎和破碎的岩石碎片，经挤压的高温融化并在火山口喷发出来。

After many times of embedments and observations for upward rock deformation observation instrument , defects for upward rock deforma tion observation instrument during grouting and improvement are discussed .

摘 要：在进行多次岩石抬动变形观测装置的埋设和观测之后，对灌浆施工过程中，岩石抬动变形观测装置在实际中存在的缺陷及改进措施作了探讨。

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。

The study on petrology, geochemistry and isotope geology indicates that there are the common resource and tectonic setting for the Kangbutiebao formation with metamorphic volcanic rocks and the granite plutons related to the main iron deposits.They are different facies from magma evolvement in late Silurian-early Devonian.

岩石学、岩石地球化学及同位素研究表明，康布铁堡组变质火山岩、与主要铁矿床有关的花岗岩具有同源、同构造环境特征，是晚志留世-早泥盆世岩浆演化的不同相。

Based on the selection of similar structure, a method for predicting the rock drillability of wildcat well is proposed.

该方法首先应用已钻相似构造井的地震资料、测井资料以及岩心测试资料，建立岩石可钻性钻前预测遗传神经网络模型，然后将神经网络与遗传算法有机结合起来，以神经网络理论为基础，利用遗传算法优化隐含层神经元个数和网络连接权值，最后利用野猫井的地震资料进行岩石可钻性钻前预测。

Analytic solution and numerical solution are obtained for predicting tunnel water inflows and water head under the condition of an exponential decrease of hydraulic conductivity with depth in an isotropic jointed rock mass.

根据各向同性岩石中隔水边界与水平方向的夹角，在岩石渗透性随深度呈负指数衰减条件下，分两种情况给出了二维稳定流隧道涌水量的解析解和数值解。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
