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。Through analysis of potential vorticity in isobaric surface field, in low - troposphere a positive potential vorticity disturbance exist and form incline disturbance column northward before rainstorm generation, at the same time have also reflected positive potential vorticity disturbance for severe convection weather trigger role in lower - troposphere ; soon positive potential vorticity disturbance in high - troposphere downward, form one vertical disturbance column, now corresponding precipitation develop stage ; in the prosperous stage of rainstorm that maintains isolines of horizontal distribution and still have straight positive potential vorticity disturbance in 600 - 700 hpa isobaric surface field ; when near ground arises negative potential vorticity disturbance, precipitation also weaken
通過對等壓面的位渦分析，發現了在暴雨發生前，在對流層低層有正位渦擾動存在並向北形成傾斜的擾動柱，同時也反映了對流層低層正位渦擾動對強對流天氣的觸發作用；隨后高層正位渦向下擾動，形成一個垂直擾動柱，這時對應降水的發展階段：在暴雨的鼎盛階段， 600 700hpa上空維持水平分佈的等值線，在其上還有正的位渦擾動；當近地面出現負的位渦擾動時，降水隨之也減弱。These all show pronounced stratification. there are three kinds of neurons related to the optic lobes : amacrine cells, columnar neurons and tangential neurons, only a few of which are stained
視葉包含三種神經元：無長突神經元、柱狀神經元和切向神經元，其中只有少數被標記，與前腦間的神經通路呈弱陽性反應。For gantry - moving type machining center servo system, in order to restrain the machine coupling influencing dual motors system, an adaptive decoupling control technology is first presented in this paper, and through feedforward decoupling ; the dual linear motors controller ' s parameters will be modified by the feedback. the synchronous control caused by the feedback resulting from the adaptive control law will keep synchronism with dual motors in position for realized synchrodrive
針對龍門移動式鏜銑加工中心伺服系統，為了克服因兩個龍門立柱運動狀態差異形成的機械耦合對雙電機系統的影響，本文採用自適應解耦控制技術，先通過前饋解耦，再經過自適應律產生的反饋作用來修改雙直線電機控制器的參數，產生同步控制量，使雙電機在位置上保持一致，從而實現了雙電機的同步傳動。In the new plan, the position of the studied strata in the stratigraphic column of late precambrian of china shows an impotant relation between sinian system and qingbaikou system on the geologic and biologic evolution
