查询词典 Angles

By analyzing the relations of two adjacent waves in the process of locomotion and doing an approximation of the serpenoid curve, the motion function of relative angles between two adjacent links and the absolute angles between each link and the baseline on the traveling curve are built.

通过对蠕动运动过程中相邻2个波形的分析和对serpenoid曲线的近似，建立了运动波形上各相邻连杆间的相对角度运动方程和各连杆与基线之间的绝对角度运动方程。

The results show that the surface roughness decreases with increase of the inclination angles within the range of 10° to 30°. After the angle approaches to 30°, increase of the inclination angle causes increase of the surface roughness. Furthermore, the effect of inclination angles on cutting speed was investigated.

研究结果表明：工件倾角的大小对已加工表面粗糙度有明显的影响，在倾角为10°～30°时，表面粗糙度随着工件倾角的增大而降低；此后，随着倾角的进一步增加，表面粗糙度有所升高。

The magnitudes of angles are usually measured anticlockwise. But a protractor usually has two sets of numbers representing clockwise and anticlockwise degrees. So it's very convenient for measuring angles.

角度的大小通常是以逆时针旋转的方向来衡量，但量角器上面通常有顺时针和逆时针两种方向的刻度，所以测量起来很方便。

In fact, a triangle formed for example, by the northern halves of two meridians and the section of the equator between them, will have two right angles at its base and an arbitrary angle at the top-a sum clearly greater than two right angles.

实际上，比如说，一个由北半球的两条子午线和它们之间的部分赤道组合成的三角形，将有两个直角作为底角，还有一个为任意角度的顶角-很显然它的内角之和比两个直角和要大。

In the same circle or congruent circles, the circumferential angles opposite to the same arc or the equal arc are equal, and equal to half of the central angle opposite to the arc; The arcs opposite to the equal circumferential angles are equal.

在同圆或等圆中，同弧或等弧所对的圆周角相等，都等于该弧所对的圆心角的一半；相等的圆周角所对的弧相等。

The major purpose of this article was to illustrate the innovating instruction of the topic-"triangle" for the third graders. From the experience of the classrooms, it is considered that the curriculum is only to instill into children some geometric nouns, such as the sides, the apexes and the angles. A closed graph with three angles is usually to be named as a triangle without thinking about children's understanding of the real meaning.

本文的主要目的乃是针对教学者本身以往在教国小三年级学童的「三角形」这个单元时，自觉只是在灌输孩子一些几何的名词，例如：这个就是边、顶点和角；有三个角的封闭图形就是三角形，并没有去考虑到孩子是否真正的理解这些语词的涵意。

The stiffness-strength and dynamic properties of the composite material barrel is the function of the winding angles and volume fractions of the composites and the winding angles can be determined by the optimization.

复合材料身管的刚强度和动力特性均是缠绕角和复合材料含量的函数；缠绕角可以通过优化设计的方法来确定。

First, according to a phase matching condition of electromagnetic wave on the stationary boundary surface, we find the refelection and transimission angles in the front system with a static ionization front. Then using the transformations of wave vector and frequency we get the corresponding angles in the laboratory system in which the ionization front is moving at relativistic speed.

首先在波面参考系中根据电磁波在固定边界上的相位匹配条件，确定电磁波在静止电离波面上的反射角和透射角，并利用波矢和频率的相对论变换，导出了在实验室参考系中相应的反射角和透射角的表达式，最后对所得的结果作了进一步的讨论。

Analyzed the changing of energy loss in turbine cascade with different backward wedge angles,and achieved the range of the backward wedge angles corresponding of the minimum energy losses on three typical sections in the turbine cascade.

分析了叶栅能量损失系数随不同后楔角的变化，得到了在该涡轮叶栅内对应最小能量损失的3个典型截面上的后楔角的范围。

Use the fortran to compose the related experience formulas for solar energy. The purpose of stylization is to expect that we can use formulas to control the angles of motor rotating the faceplate to face the sun correctly to increase the efficiency of absorbing solar radiation in the future. The contents of formula include the corresponding angles between the sun and the earth, calculating the the absorption radiation of photovoltaic cells and the design and analysis of photovoltaic system.
