埃达克岩存在两种成因类型：一种由俯冲的年轻(≤2 5～ 30 Ma)大洋板片熔融形成；另一种由增厚地壳环境中的玄武质下地壳熔融形成。

In order to develop Li Siguang's academic thoughts,this paper reviews the creation process of Li Siguang's "safety island" thought,briefly introduces the development process of the thought from "safety islands and stable masses" to "regional crustal stability" and summarizes the main factors and methods for regional crustal stability evaluation.

为了弘扬李四光的学术思想，本文回顾了李老"安全岛"学术思想的创立过程，简单介绍了在工程实践中，从"安全岛和稳定地块"到区域地壳稳定性评价的发展过程，并结合作者多年的研究积累，归纳了区域地壳稳定性评价的主要因素和技术方法。

Following the idea of "Safety Island"the crustal stability zonation map of China (1:5000000)is first compiled on a grid basis in different steps using fuzzy synthetic judgement ,image recognition and an expert appraisal system.

中国区域地壳稳定性评价图，是根据"安全岛"理论，采用网格划分，逐层应用模糊综合评判和图象识别，以及区域地壳稳定性评价专家系统的步骤和方法编制完成的。

The processing method and precision of two stages of GPS data for the crustal deformation monitoring in southeast coast of the Fujian Province are discussed in more detail, and the main features of current crust movement are primarily analyzed by comparing the two stages of GPS ob serration s.

对福建东南沿海GPS 地壳形变监测网的两期观测资料的处理方法及其精度进行了深入讨论，并根据复测资料的对比，对该地区现今地壳运动的基本特征进行了初步的分析。

Based on the subcrustal mantle convection-generated stress field inversed by gravity anomalies, together with its relationship to the Cenozoic volcanism in the plateau, and the mechanism of crustal fracture formation, as well as the numerical results of the evolution of mantle convection beneath the plateau, this paper investigates the deep mechanical mechanism for the formation of a magma transportation channel in the Tibetan Plateau.

为了研究火山形成基本要素―岩浆运移通道的形成，基于重力异常反演的青藏高原下地壳底部的地幔对流应力场，结合地壳破裂形成机理和对流应力场与青藏高原新生代火山分布的关系，以及青藏高原下地幔对流演化的数值模拟结果，分析了高原火山岩浆运移通道产生的深部力学机制。

Whereas the high conductive layer in the northern crust is connected with Asian continent′s resistance against the northward underthrust of India plate and the southward underthrusting of Asian continent.

研究区内的冈底斯及羌塘地体的中、下地壳普遍发育高导层，反映了印度大陆碰撞、俯冲过程的效应与痕迹，而高导层之下的高阻块体则可能是向北俯冲、冷的、刚性的印度大陆地壳。

The upper crust and the lower crust can be also divided to two layers.

上地壳和下地壳又可以各分为2层。

In general, the composition of lower crust is close to basalt and the composition of upper crust is similar to granite.

一般来说，下地壳的成分接近于玄武岩，而上地壳的物质成分与花岗岩相似。

From the middle to the east, the material in upper crust has diversity, but that in lower crust has continuity.

从中部到东部，上地壳物质存在差异，而下地壳物质存在一定连续性。

In this model, a parameterized method has been employed to decrease or eliminate vertical deflection and vertical refraction errors.4 For the long baselines of Crustal Movement Observation Network of China, using the GPS satellites orbits and stations positioning analysis software GAMIT opened up by MIT to do the single day GPS observation data processing, a synthetic solution model, which is called "the synthetic solution model of baseline vectors", has been built up with several single day baseline vectors calculated by the GAMIT software, to compute the three dimension movement velocities of sites.

对于长基线的GPS地壳变形监测网，采用MIT开发研制的精密GPS定轨定位软件GAMIT进行单天GPS观测数据的处理，提出了利用多期单天的GAMIT解算出的基线向量进行综合解算的模型："基线向量综合解算模型"，用以计算地壳监测站点的漂移速度，并通过实例验证了该计算模型的正确性和可靠性。

The labia have now been sutured together almost completely.The drains and the Foley catheter come out at the top.

此刻阴唇已经几乎完全的缝在一起了，排除多余淤血体液的管子和Foley导管从顶端冒出来。

To get the business done, I suggest we split the difference in price.

为了做成这笔生意，我建议我们在价格上大家各让一半。
