棱錐面 的英文怎麼說
中文拼音 [léngzhuīmiàn]
棱錐面
英文
pyramid surface-
The beyond is the simple notation of serial number of pricker, totaled 7 digits of codes, in which the first digit represents the diameter of needle - bar of pricker, the second digit represents the siding of triangle side on functional section of pricker, the third digit represent the length of functional section of pricker, whereas in standard notation, it represents the distance from needlepoint to gradual deflating small port ( lower port ), the fourth digit represents the total length of pricker, which is the distance from the inside of bending helve to the needlepoint, the fifth digit represents the total quantity of dents on the cording of functional section, and the sixth digit represents the model of barb on functional section, while the seventh digit represents the distance between barbs on functional section
以上為刺針編號的簡單寫法，共7位代碼，第一位是刺針針桿的直徑；第二位是刺針工作段三角面的邊寬；第三位是刺針工作段的長度，同標準寫法所不一樣的是針尖到漸縮錐小口（下口）的距離；第四位是刺針的總長度，按彎柄內側至針尖的距離；第五位是工作段棱上的總齒數；第六位是工作段上鉤刺的型號；第七位是工作段上鉤刺與鉤刺之間的距離。The effective reflection area of a cubic corner reflector is defined, it is testified for the cubic corner reflector that the ray reflect from this prism is not parallel with the ray incident on the corner of undersurface of this prism, the effective reflection area is calculated in the case of the ray incident on the undersurface of this prism vertically, the acreage of the effective reflection area is two thirds as that of the undersurface of this prism
定義了立方角錐棱鏡的有效反射區，證明了立方角錐棱鏡底面角部區域（即非有效反射區）入射光與出射光不平行，並且在入射光垂直棱鏡底面入射情況下計算得有效反射區的面積為底面的三分之二。In the experiment, we use the he - ne laser and the semiconductor laser as the source, record the bessel beam patterns behind the axicon by using a digital camera and a microscope, measure the radius of the bessel beam central spot by film - scanning and measure the effect of both the radius of the aperture and the open angle of the axicon on the maximum non - diffraction distance. the experiments show that a specific propagating range has constant power and the beam has a bessel - like distribution in this range. the results agree with the beam corresponding to a diffraction free beam
同時我們還採用膠片掃描的方法測量了無衍射光束的中心光斑尺寸，測量了不同光闌孔徑和不同稜角情況下的最大無衍射距離和傳播軸附近橫截面內微小光孔中的光強，實驗結果顯示當激光光束經過軸棱錐轉換後有一段距離功率變化很小，且分佈近似貝塞爾分佈，符合無衍射光束的特性;經過聚焦后，呈現三維分佈中空的光束bottlebeam ，實驗結果與理論分析基本吻合。The formulas of lateral area, surface area, and volume of pyramid can be given by vector method
立體幾何中棱錐的側面積、全面積、體積公式都可用向量方法給出。Including : the realization and motion method of weld machine working location, the technical method for circular cross - section, rhombus cross - section straight tube and cone tube, and introduced some actual examples of pressure fittings, operating system, motion mechanism ' s construction feature and disposition of the weld machines
包括：合焊機組工位移置的實現方法和運行方式；圓形和棱形截面的直管、錐管整形的工藝方法；通過實例介紹了行車式巨型管合焊機組壓力裝置、操縱系統、行走機構結構特點和焊接設備的配置。More attentions are taken to the applications of the interferometer for the quantificational and real - time measurements in the following aspects : the laser ' s wavefront, the homogeneity of laser bar, angle deviation of flatness optical components, and surface roughness
重點研究了數字式波面干涉儀的應用，定量、實時測量了激光波前質量、激光棒波前畸變、利用波面計算錐體棱鏡角度、表面粗糙度等。分享友人
