橢球鏡 的英文怎麼說
中文拼音 [tuǒqiújìng]
橢球鏡
英文
ellipsoidal mirror-
A theoretical and experimental study of a new, efficient technique to couple a laser, emitting a highly elliptical beam, to a single - mode fiber without the use of bulk optical components is presented. the technique involves butt coupling the laser to a cylindrical lensed fiber and spherical lensed fiber
本文從理論上和實驗上呈現了一個實用的耦合技術，即在沒有使用分立球形光學元件的情況下將高度橢圓化的激光光束通過透鏡光纖耦合到單模光纖中。After the comparing the simulation results with the theoretic results under the three followed condition : a point light source on the parabola reflector focus, a point light on the ellipsoid reflector focus and a point light source before the parabola reflector focus, a conclusion is gotten that the two results are generally accordant, the accuracy of the simulation software reach the engineering requirements and the computational simulation software of photometric characteristics of headlamp of motor vehicles can guide the design of the headlamp reflectors
比較了點光源位於拋物面反射器和橢球面反射器焦點的情況和點光源偏離拋物面焦點的情況下照度的理論計算結果和採用本文的照度模擬計算結果，其模擬計算結果和理論計算結果基本相符，能滿足工程上的要求，說明模擬計算軟體對前照燈的反射鏡的設計具有很好的指導意義。Off - axis ellipsoidal mirror
離軸橢球鏡Phase composition of nanometer tio2 is analyzed by x - ray diffraction, granule size and appearance of nanometer tio2 are analyzed by scanning electron microscope and transmission electron microscope, so we modified the conditions of experiment and obtained even and dispersive nanometer grade rutile tio2 powder that is spheric or oval - shaped
通過x射線衍射、掃描電子顯微鏡、透射電子顯微鏡和原子吸收等檢測分析研究，改進制備工藝條件，合成了粒度較均勻、分散性較好的球形或橢球形金紅石型納米級tio _ 2粉體。分享友人
