等腰三角形

In section 2, we use skills in analytic geometry to study the theory of the companion centers of nonisosceles triangles.

在第二节中，我们用解析几何中的技巧研究非等腰三角形的伴心理论。

Is the set of the barycenter of if is a regular triangle, and is the perpendicular bisector of the base if is a nonregular isosceles triangle.

当 为正三角形时，是的重心所成的集合，当为非正三角形的等腰三角形时，是底边的中垂线。

As the equation of the curve determined by companion centers shows, our main result is that the set of all companion centers of a nonisosceles triangle is the unique equilateral hyperbola, called the hyperbola of , passing through the vertices ,, and the barycenter of .

透过伴心轨迹方程式我们得到主要结果如下：非等腰三角形的伴心所成的集合是一个通过三顶点、、及重心唯一的等轴双曲线，称为的双曲线。

I predict that chinese government will invest 3 highspeed railway like the one from beijing to shanghai.

我预测政府将同时投资建设连接北京、上海和广州3大都市的高速铁路网，连成一个等腰三角形。

In this way, the isosceles triangle of a "waist" painting it.

在这样，等腰三角形的"腰"绘画。

" Looking from all sides, which are great on the small of the isosceles triangle, much like English "pot of gold" character so that people on the image to be called "pyramid.

从四面望去，它都是上小下大的等腰三角形，很像中文"金"字，所以，人们就形象地叫它"金字塔"。

In this paper,from the view of engineering application,under the condition that three control points formed an isosceles triangle,the relationship is studied between the error of P3P pose estimation methods and the input parameters.

从工程应用的角度出发，在三个控制点构成等腰三角形的条件下，研究P3P位姿测量方法的误差与输入参数误差的关系。

The lowest energy structures of phosphorus-excess triatomic clusters are an isoceles triangle with C2V symmetry, and metal-excess triatomic clusters show minimum energy configurations to be a triangle with Cs symmetry.

富P的MP2团簇是具有C2V对称性的等腰三角形结构，而富M的M2P团簇则是具有Cs对称性的三角形结构。

The birth of a True Equilateral Triangle from Isosceles parents is the subject of rejoicing in our country for many furlongs around.

一对等腰三角形父母如果生出真正的等边三角形，这在方圆百里都是件大喜事。

Such a birth requires, as its antecedents, not only a series of carefully arranged intermarriages, but also a long, continued exercise of frugality and self-control on the part of the would-be ancestors of the coming Equilateral, and a patient, systematic, and continuous development of the Isosceles intellect through many generations.

正如前例，这样的出身不仅需要一系列小心安排的通婚；而且需要未来的等边三角形的那些所谓的祖先，在节俭与自控方面，进行长期的、连续的训练；另外，等腰三角形的智力要历经几代的努力，耐心的、系统的、持续的发展。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
