Then interpolating cubature formulae is given based on Lagrange interpolation formulae. Secondly it make use of the cubature formula on the triangle to construct cubature formulae on the correspondent spherical triangle.

通过把其定义域上的积分化为平面单纯形{u =(u1， u2， u3)： u1 + u2 + u3 = 1， u1， u2， u3〉0}上的积分，然后利用平面单纯形上数值积分公式给出其在球面三角形上的对d次齐次多项式精确成立的Gauss求积公式的构造方法。

The main purpose is to construct cubature formulae on an arbitrary spherical triangle. Firstly a method for accurately computing the definite integral of spherical polynomial functions on a spherical triangle is proposed.

本文主要研究定义在球面三角形上函数的数值积分，通过积分的插值多项式函数构造具有多项式精度的插值型求积公式，以及给出精确计算球面三角形上多项式函数方法。

For example ,many sings on the road tell dirvers what to do .when you see a triangle with two chiildren crossing the road ,you must not dirve too fast because there is a school nearby,and school children may cross the road.a sign with the letter " p "means you can park here .and a triangle with an arrow means turning left or right .also at crossing, traffic lights use three different colours as sings :a red light means " stop ", an amber light means "get ready for stop" and a green light means"go ".some road signs warn us of possible danger.

它们简单易懂。比如说，很多在马路上的标记告诉司机们该做什么。当你看见一个三角形标记里面有两个小孩横穿马路的时候，你最好不要开得太快，因为附近有一个学校，学校的孩子们会横穿马路。带有"P"字的标记说明你可以在这里停车。还有带着箭头的三角形标记就意味着左转或右转。还有在十字路口，交通灯用三种不同的颜色最为标记：红灯停，琥珀色的灯意味着"准备要停下了"还有绿灯就是行的意思了。一些马路标记警告我们一些可能存在的危险。

This is indicated in Figure 5.6 by the difference between the triangle E'd'h and the triangle Edh (for firms that "enter" the industry in response to a rise in price from OE' to OE, the return increases from zero to a positive amount).

7在图5.6中，这种收益增加显示为E'd'h三角形与Edh三角形的差别（对于因价格从OE'到OE的上涨而"进入"该行业的厂商而言，这收益是从零增加到一个正值）。

You may only use elementary geometry, such as the fact that the angles of a triangle add up to 180 degrees and the basic congruent triangle rules (side-angle-side, etc.).

这门课在西方的对应一般叫Linear Algebra，就是苏联人喜欢用高等这个词，你可以在外国教材中心里面找到一本Kurosh的 Higher Algebra。

It is called Equilateral Triangle that a triangle has equal legs.

三条边都相等的三角形叫做等边三角形。

Like Picture 2, a triangle with three same sides is called an equilateral triangle.

象（2）一样，有三条边相等的三角形叫做等边三角形。又叫正三角形。

Triangle with three equal sides is called equilateral triangle.

*三条边都相等的三角形叫做等边三角形。

The epidemiologic triangle consists of three components, with the Host at the top point and the Agent and the Environment at the other two points of an equilateral triangle.

流行病三角形由三部分组成，包括在等边三角形顶端的宿主，和在两个底角处的病原和环境。

It should be noted that whether the Country Point 4 is located inside the Exterior Opposite Angle Area or inside the triangle, it finally forms one same graphics which we call here Basic Triangle with Four Points Entirely Neighboring.

需要注意的是，国家点4无论落在三角形的外部还是内部后形成的四点全相邻布局，其基本图形是一致的，即四点全相邻基本三角；此时4色足够，而且这也是需要4色的基本图形。

The absorption and distribution of chromium were studied in ryeusing nutrient culture technique and pot experiment.

采用不同浓度K2CrO4(0，0.4，0.8和1.2 mmol/L)的Hoagland营养液处理黑麦幼苗，测定铬在黑麦体内的亚细胞分布、铬化学形态及不同部位的积累。
