查询词典 vertex angle

When the voltage space vector is in the overmodulation II, the reference voltage is no longer tracking the circle of radius and holds an angle at the vertex and then moves along the hexagon.

在上塑料托盘述线性调制的基础上，提出一种基于电压空间矢量的过调制方法。

Based on the improvement of Taubin s discrete curvature estimation method of triangular mesh by the adoption of area and angle weighted triangle vertex normal vector calculation formula and triangle centroid weights, a novel algorithm for triangular mesh regularization is presented.

采用面积夹角加权的三角网格模型顶点法矢及三角片质心权值对Taubin的三角网格模型离散曲率计算方法进行了改进，在此基础上提出了一种新的三角网格模型优化调整方法。

Consequently, the vertical TEC around the receiving station was exported. Through this method, the vertical TEC got is an average value of a prick angle around the vertex. With the statistics of dispersion and the high precision data collected in Kunming station, the authors calculated the day by day time sequence value of total electron content in altiplano zone ionosphere. Based on this, they described the characteristics of TEC Sunday-changing in double-hump zone, comparing with CORS of Kunming.

这种方法得到的垂直TEC为天顶周围一锥角内的平均值，通过离散度的统计，并结合昆明站采集得到的高精度数据计算了该地区电离层2007年6~8月的电离层电子浓度总含量的逐日时间序列值，在此基础上对照昆明市连续运行参考站CORS描绘出了对于处在双驼峰区里该地区TEC日变化的特性。

As Yukio Hatoyama wants Japan to interact more with China, the right triangle in which China is at the vertex of a small acute angle and Japan and the US at the other two vertices may become one that is more like an equilateral triangle. Clearly, Yukio Hatoyama sets greater store by China than Taro Aso.

鸠山由纪夫的外交理念是增加与中国的互动，人们也许会看到东北亚中、美、日三角，会由往昔的直角三角形的美日在一边而中国在另一边，调整到类似等边三角形。

The method reconstitutes the triangles in different multi-resolution transition region and optimizes the quadtree vertex error estimation and geometry smooth transition algorithm with the scheme based on the characteristics of higher distance to ground and bigger downwards angle of visibility in flight simulation. The render speed of computer is enhanced while ensuring the veracity condition of the terrain.

该方法将不同分辨率过渡区域的地形进行重新构网，并针对飞行仿真距离地面较高、下视角较大的特点对四叉树顶点误差估计和几何光滑过渡算法进行优化，在保证地形准确性的范围内提高计算机实时处理速度。

In partial celestial sphere celestial Star-Identification, the initial attitude is known. With a certain angular and distance tolerance, the separation angle of the observed stars and that of the catalog stars are matched, then, the star triangles are composed in real time. According to the rules of vector rotation, the inconsistent rotation star triangles are removed. After that, put the star triangles with public vertex into star polygon.

在局部天球星图识别方面，因为已知初始姿态，在一定角距容差和星对容差范围内和已知视轴附近的导航星角距表进行角距匹配，实时组成星三角，根据矢量法则剔除旋转方向不一致的星三角后，再把拥有公共顶点的星三角组合成星多边形。

Kuehl's triangle Star-Identification, some improvement had made. With a certain angular and distance tolerance, the separation angle of the observed stars and that of the catalog stars are matched, then, the star triangles are composed in real time. According to the rules of vector rotation, the inconsistent rotation star triangles are removed. After that, put the star triangles with public vertex into star polygon.

Kuehl的三角形星图识别的基础上进行了改进，即在一定角距容差和星对容差范围内和整个导航星角距表进行角距匹配，实时组成星三角，根据矢量法则剔除旋转方向不一致的星三角，把拥有公共顶点的星三角组合成星多边形。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
