The research presented in this thesis concentrates mainly on two fundamental subjects on technology of filling bed separation with waste through bore-hole to reduce surface subsidence. One involves the dynamic principles of development of strata separation and the other is related to ascertaining method of parameter of grouting.

本文重点研究了覆岩离层注浆减小地表沉陷技术的两个最基本的问题，其一是采动覆岩离层的动态发展规律；其二是注浆参数的确定方法。

The dynamic cohesion of reinforced-soil increases obviously, but its dynamic internal friction angle is unchanged compared with pure soil.

一层加筋的阻尼比比两层加筋的阻尼比要大；土体的密实度对阻尼比有较为明显的影响，密实度越大阻尼比越大。

E. new extrapolation value s of finite element solutions on the first two level grids are used to provide the good initial value s on the third level grids and then an exacter finite element solution can be obtained by several CG-iterations.

摘要提出一种求解大规模有限元方程组的新外推多网格法，即用前两层网格上有限元的新外推值提供第3层细网格上的好初值，然后用几次CG-迭代能得到较准确的有限元解。

According to regionalizing indicators of average annual accumulated temperature above 20℃, average annual freezing index, precipitation in freezing period and average annual precipitation in nonfreezing period, the macro layer of the regionalization, China climatic regionalization for highway, were suggested through methods of cluster analysis, division based on indicator and layers superposing, which included 10 first-level regions and 24 second-level regions. It summarizes that climate of China affects highway in macro level.

利用多指标系统聚类分析、指标划分和图层叠置等方法，以累年年≥20℃积温、累年年冰冻指数、累年年非冰冻期降水量以及累年年冰冻期降水量为区划指标，对处于方案体系宏观层的中国公路气候区划进行了具体划分，提出了由10个一级区、22个二级区构成的两级区划方案，为了解中国气候对公路综合影响的异同性以及影响程度差异提供了一个平台。

A'trade-off'between overprosperity and overrecession, therefore, is rooted in rush expansion and contraction of investment.

在前面两层分析的基础上，第三层集中讨论从强周期波动向常规波动转变的途径，指出如何从政策调整、工业化发展战备转变及经济运行和调节机制转换来实现；国民经济持续、稳定和协调的增长。

We improved the sub-oxide quality by increasing the growth time of oxidation, and then observed that the discrepancy between them became unapparent.

我们将生长氧化层的时间增加，相当於将次氧化层的品质改善后，发现两种元件的差异性明显地减小。

During skeleton steel erection, a tightly planked temporary floor will be maintained within two stories or 30 feet (9.144 meters), whichever is less, below and directly under that portion of each tier of beams on which any work is being performed.

在主框架安装期间，在每层有人工作的梁下方或紧贴着梁的下方，两层或 30 英尺(9.144 米)之内，选低者，则要保持有一个密铺的临时平台。

A 2D two phase horizontal fracture model was established when studying hydraulic fractures for the requirement of shallow reservoir stimulation in this block; and a 3D two phase model has been built for numerical simulation of a reservoir with five-spot pattern without considering vertical fracture flow. The impacts of horizontal fracture half length and flow conductivity on recovery factor and ultimate recovery factor are studied for some certain injection and production conditions. The parameters of hydraulic fracturing are optimized.

根据该区块浅层油层改造的实际需要，研究水力裂缝时建立两维两相的水平裂缝模型，不考虑裂缝垂直方向上流动，建立了五点井网条件下三维两相油藏数值模拟模型，研究了水平裂缝半长和导流能力对油井产量、注采条件下的采收率和最终采收率等指标的影响，优化了水平裂缝参数。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。
