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.

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.

研究結(jié)果表明：工件傾角的大小對(duì)已加工表面粗糙度有明顯的影響欧美熟女口交，在傾角為10°～30°時(shí)国产精品偷啪在线观看，表面粗糙度隨著工件傾角的增大而降低日韩欧美在线视频观看；此后性a视频在线观看，隨著傾角的進(jìn)一步增加，表面粗糙度有所升高免费无码大黄网站在线观看。

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時(shí)針旋轉(zhuǎn)的方向來(lái)衡量曰韩欧美不卡片，但量角器上面通常有順時(shí)針和逆時(shí)針兩種方向的刻度，所以測(cè)量起來(lái)很方便玖玖在线资源www网。

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.

實(shí)際上99热精品3，比如說(shuō)，一個(gè)由北半球的兩條子午線和它們之間的部分赤道組合成的三角形黄色网站aaaa，將有兩個(gè)直角作為底角精品国产一区二区三区国产区，還有一個(gè)為任意角度的頂角-很顯然它的內(nèi)角之和比兩個(gè)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.

在同圓或等圓中www…爱爱…com，同弧或等弧所對(duì)的圓周角相等亚洲婷婷在线视频，都等于該弧所對(duì)的圓心角的一半；相等的圓周角所對(duì)的弧相等亚洲欧美V视色一区二区。

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針對(duì)教學(xué)者本身以往在教國(guó)小三年級(jí)學(xué)童的「三角形」這個(gè)單元時(shí)国产精品特级女人18毛片A毛片，自覺(jué)只是在灌輸孩子一些幾何的名詞，例如：這個(gè)就是邊午夜日韩电影免费观看、頂點(diǎn)和角涩涩视频A；有三個(gè)角的封閉圖形就是三角形，并沒(méi)有去考慮到孩子是否真正的理解這些語(yǔ)詞的涵意国产大片免费视频在线观看。

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.

復(fù)合材料身管的剛強(qiáng)度和動(dòng)力特性均是纏繞角和復(fù)合材料含量的函數(shù)激情无码国产一区二区；纏繞角可以通過(guò)優(yōu)化設(shè)計(jì)的方法來(lái)確定。

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.

首先在波面參考系中根據(jù)電磁波在固定邊界上的相位匹配條件自拍黄片，確定電磁波在靜止電離波面上的反射角和透射角欧美cao，并利用波矢和頻率的相對(duì)論變換三级国产网站，導(dǎo)出了在實(shí)驗(yàn)室參考系中相應(yīng)的反射角和透射角的表達(dá)式，最后對(duì)所得的結(jié)果作了進(jìn)一步的討論在线人成免费视频。

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.

分析了葉柵能量損失系數(shù)隨不同后楔角的變化日韩精品天天在线观看视频免费网站，得到了在該渦輪葉柵內(nèi)對(duì)應(yīng)最小能量損失的3個(gè)典型截面上的后楔角的范圍。

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.
