The findings indicate that there are many micro-crannies developed in marlite, which can be seen under the Scanning Electron Microscope. The micro-crannies are the precondition of karstification process. Also, the calcium carbonate is dissolved through some chemical processes, and lots of mineral mud are carried away by mechanic erosion. The karstification process results in not only mineral component transformation, but also the rock mass structure alterations.

结果表明：微观下泥灰岩岩石中发育许多微小的裂隙，为溶蚀作用的进行提供了前提条件，另外泥灰岩中大量的泥质物随可溶岩的化学溶蚀过程发生了机械侵蚀作用：泥灰岩的溶蚀作用一方面引起矿物成分发生改变，另一方面导致岩石结构的变化。

The mean square error of strength is a measurement of rock mechanics. A new model about relation between strength of rock and its sample size is set up.

研究表明，上述损伤力学模型可以近似地反映岩石的本构性能，强度分布方差是岩石材料物理性能的一种量度。

A megalithic structure is some thing big made of rock. It could be a statue, or just some rocks strewn around in a pattern.

巨石建筑物由岩石构成，它可以是一座雕像，或只是由一些岩石零星分布构成某种图案。

With the fracture profile method, the dimensions of fractal of the fracture surface of rock was measured.

用侧面轮廓线法测量了岩石断口的分形维数，结果表明，岩石的断裂韧度越大，断口分维数越小。

The data of microcrack parameters in different temperatures were processed based on statistical theory; and the regularities of distribution of microcrack parameters were obtained.

基于统计学理论，从细观层次对不同温度下的岩石断口微裂隙参数数据统计分析，得到了岩石微裂隙几何参数在不同温度下的分布概型，并运用Monte-Carlo随机模拟的方法，再现微裂隙在工程岩体中的分布。

By use of the concept of domain of microcrack growth the damaged status of micocrack in rock can be described accurately and the problem about damage development of rock under any complicated loading pathes can be solved.

采用微裂纹扩展域的概念，准确地描述了岩石中微裂纹的损伤状态，解决了任意复杂加载路径下的岩石损伤演化问题。

The gold-bearing metamorphic fluid migrates from migmatite zone and granite to upper mylonite zone and lower mylonite zone in the slip system.

本文重点强调：具有从上部主糜棱岩带—混合岩带—花岗岩带—混合岩带—下部主糜棱岩带的岩石垂向分带性的滑动系统是深层次推覆过程中断裂动热变质、超变质作用，以致长英质岩石部分熔融的产物。

Change in the mineral content of a rock because of outside influences.

Petrographically and mineralogically similar rocks quite often have different concentrations of radioactive elements.

岩石学矿物学上类似的岩石，其放射性元素丰度却往往有所不同。

Engineering disaster of swelling rock is a subject of extreme complication and momentously economic implications. How to construct projects and sustain its stability economically and effectively in such rock is always a problem puzzling many experts in rock mechanics and engineering geology.

膨胀岩的工程灾害是个极为复杂且具有重大经济意义的课题，如何才能做到经济有效地在这类岩石中建设工程并维持其稳定性，一直是困扰着广大岩石力学和工程地质工作者的一个难题。

In the United States, chronic alcoholism and hepatitis C are the most common ones.

在美国，慢性酒精中毒，肝炎是最常见的。
