本文介紹一種確定光學系統參數的新方法，包括通過參考比較已有星敏感器及其光學系統特性來選取新光學系統焦距、相對孔徑和視場；根據所選取的參數預計星敏感器的捕獲概率；採用綜合恆星光譜方法確定光學系統中心波長和光譜范圍。In this paper, micro - cavity semiconductor laser ( mcsl ) with pillar vertical - cavity surface - emitting structure ( vcsel ) which has potential applications in optical communication and optical interconnect is theoretically analyzed, the calculation model that used to discuss the modal performance of rectangular columnar and cylinder vcsel with oxidized aperture is established by using vector field model. the numerical simulations in the case of cylinder structure show oscillating wavelength and threshold gain against inside and outside radius of laser, the layer refractive index and pair number of bragg mirror, thickness, position and oxidized material ' s refractive index of oxidized aperture, in detail. more practically, considering dos shell of laser as non - perfect one, or supposing that dos shell is separated from the laser, we can obtain more significative results
本工作以矢量場模型出發，對具有誘人應用前景的柱形垂直腔面發射結構（ vcsel ）的微腔半導體激光器（ mcsl ）進行了理論分析，建立了用於分析方柱形和圓柱形結構具有氧化孔徑層的激光器的模式特性的理論模型；對圓柱形結構情況進行了數值模擬，得到了振蕩波長、閾值增益隨激光器內外半徑、 bragg反射鏡層折射率、周期數以及氧化孔徑層厚度、位置和氧化物折射率的詳細變化規律；為使理論計算更接近實際，將外加金屬包殼視為非理想導體，或將金屬包殼與激光器結構隔開，分別對這兩種情況下的結果進行了討論。The radar which is embedded on platform sidelooking, but the platform will be disturbed by airflow inevitably. so, the radar will have a small sloping angle, thereby, the doppler centroid that is not zero and doppler frequency rate need to be estimated from the raw echo data in order to focus in azimuth commendably
場景成像的合成孔徑雷達一般是正側視放置，但是載機不可避免的要受到各種擾動影響，雷達會有一定的斜視角，從而導致了多普勒中心頻率不為零，多普勒調頻斜率也隨著雷達斜視角改變。Based on biphasic porous medium model of articular cartilage, this thesis regards the solid phase as isotropic linear elastic medium, the fluid phase as ideal fluid, the deformation as small, and the permeability depending on the volume strain of solid phase, and deduce out the finite element method for this nonlinear model
本文針對關節軟骨兩相多孔介質模型，視固體相為各向同性線彈性介質，流體相為理想流體，變形為小變形，滲透率與固體相體積應變相關，研究該非線性模型的有限元法。Correctly dealing with complications caused by corneal perforation during operations is very important for the recovery of visual acuity after operation
結論在角膜穿孔傷縫合術中，使用透明質酸鈉不僅提高了手術的效率，還減少了術后虹膜的粘連，使患者的視力能恢復得更好。Fractal porous media can be simplified as a kind of binary mixture with different thermal conductivities. the calculated results show that heat transfer in fractal porous media is very complicated, the thermal coupling effect of matrix with pore structure is studied. when heat transfer in pore structure is neglected, the effective thermal conductivity for random sierpinski carpet is scaled up with the percent of matrix, which is described by the classic archie ' s law
本文首先採用有限容積法分析了分形多孔介質中的熱傳導過程，多孔介質可以視為二元混合介質，計算中發現分形結構中的導熱規律非常復雜，基質與孔隙之間存在著很強的相互換熱，當不考慮孔隙氣體中的導熱時，本文所構造的隨機sierpinski地毯上導熱系數與基質率（基質百分含量）大多呈指數關系，這與archie定律的結果是-致的。Determination of apparent relative density and porosity of industrial briquette
