Secondly, the paper has carried on the analysis to the millimeter wave blasting fuse near field target characteristic, and has produced a RCS measuring technique. The analysis is that non- atmosphere window triangle wave modulation millimeter wave blasting fuse slip frequency spectrum, which has completed under the triangle wave modulation slip frequency signal time domain and the frequency range analysis.

随后对毫米波引信近场目标特性进行了分析，并给出了一种RCS的测量方法，并系统分析了非大气窗口三角波调制毫米波引信的差频频谱，完成了三角波调制下的差频信号时域和频域分析。

For kindred reasons, geometrical propositions, that, for instance, in a triangle two sides together are greater than the third, can never be derived from the general concepts of line and triangle, but only from intuition, and this indeed a priori, with apodeictic certainty.

就连所有几何学原理也是如此，例如在一个三角形中两边之和大於第三边，就绝不是从关於线和三角形的普遍概念中，而是从直观中，并且是先天地以无可争辩的确定性引伸出来的。

For kindred reasons, geometrical propositions, that, for instance, in a triangle two sides together are greater than the third, can never be derived from the general concepts of line and triangle, but only from intuition, and this indeed a priori , with apodeictic certainty.

凭着类似的原因，几何学的命题，比如&三角形两角之和必定大于第三边&，不能从简单的线和角的概念推论出来，他们仅仅是直觉，只有矛盾的确定性。

We also define the companion angles and of a normalized triangle , there is no companion centers associated with companion angles and they are close related to the asymptotes and of the hyperbola of the nonisosceles triangle .

我们也定义正规三角形的伴角、，他们与的双曲线的渐近线、有密切的关系。

National Flag: The national flag (proportions 5 by 3 when flown on land, but 2 by 1 at sea) is green, with a white-bordered yellow triangle on which is superimposed a black-bordered red triangle.

概况 General 国名：圭亚那合作共和国 Official Name： The Co-operative Republic of Guyana 国旗：三角形箭头象征国家的前进步伐；绿色象征农业和林业等自然资源；白色象征河流和水源；黄色象征矿藏、财富；黑色象征人民勇往直前、坚韧不拔的精神；红色象征人民建设祖国的热情和力量。

Phase, forming the triangle-shaped Greek letter Delta. The load lines are connected to the corners of the triangle.

三角形连接是指在三相连接中，相临两相首尾相连，构成三角形的希腊字母Delta，负荷线连接在三角形的角上。

Not a triangle at a time, I'm talking about triangle lists, fans, strips, etc.

不是每次一个三角形，我说的是三角形列表、扇形、条带等等）。

A triangle strip is extruded backwards and forwards in time such that the middle triangle is always at the current time.

沿着运动时间抽取一条三角条带，中间三角形代表当前时间三角形的位置而前后的三角形分别代表过去和未来的三角形位置。

As each section of the triangle strip is extruded, it is given an alpha value based upon how much time has elapsed between the time represented by this section of the strip and the current time (the triangle in the middle of the forwards and backwards strip).

在三角条带的每一段都被抽取出来后，它被赋予一个 Alpha 值，该值由这个条带代表的时间和当前时间的时间（处于过去条带和将来条带之间的三角形代表的时间）差来决定。

The original STL model is progressively reorganized into a structured triangle mesh by using half edge pointers and hash table indexing to linking adjacent triangles. All redundant vertices are eliminated and at the same time the topology of triangle mesh is set up.

首先通过半边匹配确定新增三角片的类型；然后针对每一种类型使用不同的方法去除冗余顶点，并同时建立拓扑关系；最后通过顶点数组紧缩消除顶点空隙，将半边hash表转化为半边数组，完成网格模型的重建。

The work of this paper is as follows: 1. Looking back the progressing history of the linear motor, introducing the features of the elevator driven by linear induction motor, radicating the topic of this paper "the digital frequency variable control of the elevator bi-side direct driven by linear induction motor". The research of this paper covers the conventional VVVF control, space vector based VVVF control, vector control and DTC.

本文主要开展了以下几个方面的工作： 1 回顾了直线电机发展历史，电机的驱动技术演变，特别是针对直线电机的驱动，简要介绍了直线感应电机驱动电梯的优点和不同结构类型，对传统的v／f控制，基于空间矢量法的v／f控制，矢量控制，和基于电压空间矢量的直接转矩控制进行了比较，确立了本课题的研究主题：直线感应电机双边直推式驱动电梯的全数字变频控制。

The article combines with the treatment of a superficial civil air defense work to introduce how the grouting method to improve the performance of the backfill soil.
