Based on the analyse of the stratigraphic sequence of the Triassic and its covering strata and the Index of the Organic Metamorphic Maturity of conodont, the Triassic of the northern margin of the Gongdise-Nyainqentanglha Stratigraphic Region and the South of the Qiantang Stratigraphic Region was a promising target for the oil exploration.

通过三叠纪时期的沉积体系的时空演化序列，分析出三叠纪在冈底斯北缘、羌南地区形成了有利的生储盖的岩相配置，通过盆地热演化史和牙形石有机变质成熟度的分析，指出冈底斯一念青唐古拉地层区北缘和羌南的三叠系具有良好的油气勘探前景。

The conodont study indicates that the thick carbonate rock strata belongs to the Majiagou Formation of the Middle Ordovician. The Upper part of the formation has the conodont fossil Erraticodon tangshanensis, the lower part is represented by Tangshanodus tangshanensis.

牙形石研究表明这套厚层质纯的碳酸盐岩地层属于中奥陶统的马家沟组，含有上部以Erraticodon tangshanensis为主，下部以Tangshanodus tangshanensis为特征的牙形石。

The strata takes care of all the common property and services and collects the fees which go into a contingency fund for future needs new roofing etc.

照顾各阶层的共同财产、服务及所收取费用的投入应急基金未来需求新屋顶等

He tried to guess how the strata behaved at the time the contortions formed.

他试图推断地层在扭曲形成时是如何变化的。

The geologist needs to know what rocks the drill has reached, so every so often a sample is obtained with a coring bit. It cuts a clean cylinder of rock, from which can be seen the strata the drill has been cutting through.

地质学者需要了解钻探到了什么岩石，所以经常会从钻头穿过的岩层中得到一些岩石样本，切割岩石成为圆柱体。

The paper has studied the strata distributive character and engineering geologic property of bed rock zone of weathering in cryptical coal field, based on large of data form testing and real-field materials, taking importance on the laws of overlying destruction and underground pressure behavior and the mechanism of decreasing protective coal columns while extracting proximity zone of weathering .

以大量实验数据和现场测试资料为依据，研究了隐伏煤田基岩风化带岩体的分布特点及工程地质特性，重点论述了邻近风化带开采的覆岩破坏和矿山压力显现规律以及缩小防护煤柱的机理，为类似矿井的资源回收与安全开采提供了依据。

By considering torque characteristics of variable-frequency motors and mesh stiffness as well as backlash nonlinearity in gear transmission,a dynamics model for the cutting system of shield tunneling machine with redundant drives was established. The fluctuation characteristics of torque loads and dynamic cutterhead driving torque in composite strata were analyzed.

复合地层掘进扭矩载荷突变是造成盾构机掘进过程中堵转停机的直接原因，考虑盾构机刀盘驱动变频调速电机特性、转矩传递过程中齿轮啮合刚度及齿侧间隙等非线性因素，建立冗余驱动的盾构机刀盘切削系统机电耦合动力学模型；针对典型复合地层地质条件，对盾构机在上软下硬地层掘进过程中刀盘驱动转矩动态特性进行仿真分析。

The study of fossils, or paleontology, was made popular by French anatomist Georges Cuvier (1769-1832) who pointed out that the deeper the strata, the less similar the fossils are from modern existing life.

研究化石，或古生物、流行是由法国anatomist乔治cuvier(1769年至1832年)指出，更深的地层，类似的化石较少从现代生命存在。

Georges Cuvier had looked at fossils in rock strata and observed how the ones that lay deeper looked less like familiar animals. But Etienne St. Hilaire observed that all living animals had similar organs and anatomies. To Jean-Baptiste Lamarck this meant that, over time, all animals were changing their form.

乔治·居维叶通过观察岩石层中的化石发现：岩层越深，化石与相类动物的共性就越少；然而艾奇恩那·圣伊莱尔却发现，所有活着的动物都有着相似的器官和身体结构；在让·巴蒂斯特·拉马克看来，这意味着所有动物都随着时间的推移改变着它们的形态。
