查询词典 singular boundary point

In scientific selection of dewatering plans during the excavation of a deep foundation pit, the muti objective fuzzy decision making method is used, which comprehensively considers various indexes such as technique, economy, construction and operation. The fuzzy decision making model of scientific selection under the condition of complex geologic and boundary conditions is established, and the weights of quantitative and qualitative objectives are analysed, and the scientific decision result from synthesizing four factors is obtained.

The strongest structural activity during the Yanshan movement is the Ⅱ phase, It had three pulsation and formed large-scale tectonic system with dextral strike slip.

早、中侏罗世，断裂带作为北界，控制了由西向东一系列煤系盆地的沉积作用和岩浆活动；在燕山运动的Ⅰ、Ⅱ、Ⅲ幕中分别形成了一系列逆冲构造；其中，以燕山Ⅱ幕构造活动最强，并至少经历了三次脉动作用，形成的逆冲构造不是由盆缘到盆内的&对冲&，而是受本断裂带限制，并以之为主滑面构成了区域上的大型右行走滑斜压式构造系统。

Skinner seeks for negative free theory of republicanism and the neo-Roman in the history. This kind of free theory was different from the tradition of the liberal thought which occupies hegemony in present ideological circle. It doesn't emphasize the explicit boundary between the personal life domain and the public authoritative domain, but emphasizes the citizen's positive participation in the political life.

斯金纳在历史中找寻到共和主义和新罗马消极自由理论，这种自由理论与当今思想界占据霸权地位的自由主义思想传统不同，它并不强调私人生活领域与公共权威领域之间的明确界限，而是强调公民对政治生活的积极参与。

It is this boundary-work that makes the typology useful for avoiding extreme technological determinism, social constructivism, and noetic flatness in conceptualizing an artifact's political qualities, and for thinking about how these qualities change through time.

正是这种边界的工作，使避免极端的技术决定论，社会建构主义类型学有用的，在构思一个工件的政治素质智力平坦度，以及思考如何通过时间改变了这些特质。

D models are the most widely spread in the world of turbo-machinery for its simplicity, but they are indeed purely empirical correlations which not only fail to provide detailed information inside one or more components, but also require significant effort to recreate themselves if engine operating conditions or component representations change; quasi 3-D models have been the workhorses for compressor and turbine design for many years, and the primary benefit of using quasi 3-D system models is to facilitate the design and detail analysis of a particular component across the range of possible boundary conditions; Full 3-D models are gradually replacing quasi 3-D ones by virtue of requiring no exit flow angle model and loss model and being capable of predicting secondary flow in cascade.

零维模型由于使用时简单易行，因此在涡轮发动机的仿真中得到广泛应用，但零维模型作为纯粹的经验关系式无法反映部件内部的流动细节，并且一旦部件有少许改动则新特性的建立耗费巨大；准三维模型由于能够详细地提供部件内部的流动情况，方便设计而成为涡轮和压气机设计的主要工具；全三维数学模型正逐步取代准三维模型在涡轮设计中的主导作用，同后者相比前者能够预测叶轮机械内的二次流动，在粘性流计算时不需要气流角和损失的经验公式，因此拥有巨大的发展前景。

In addition, the welding seam strength has been investigated by the method of fracture mechanics, and the software for calculating stress intensity factor at crack tip in weldments has been worked out by boundary element method.
