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。Refractory for fertilizer equipment is developed by this factoy according to the analysis and research of refractory material for synthetic ammonia equipment, which is suitable for the synthetic ammonia equipment in china, and can be used as heat insulation lining for 1 - phase converter and 2 - phase converter. besides, it can satisfy the requirement of long term safe wirking
公司在引進合成氨裝置不定型耐火材料的基礎上開發研製了系列耐材,該系列產品具有強度好、使用溫度高、隔熱性能好等特點,完全能滿足一段轉化爐、二段轉化爐等裝置的長周期運行。Following are detailed steps of this system : in the segmentation section, we use three successive frames to detect the motion infomation of the pictures, by using blockmatching algorithm in two successive frames twice, we can get two pictures composed of motion blocks of the moving object, then we find out the common motion blocks of the two pictures, experiments prove these blocks approximately compose the moving object. after getting the motion blocks, we calculate the center of these blocks as the center of the moving object, thus we can use the center point as the origin, construct n straight linesjoining the boundry of the image and the center. on each line, we can find out a proper point near the object contour according to some criteria, then we use these n points as the initial points of the snake and let the snake converge on the object contour, thus finish the segmentation of the moving object
本方案的實現過程為:分割部分:對運動目標的前後三幀進行兩次塊匹配運動檢測,通過找出兩個匹配結果中運動圖像塊的公共部分,獲得組成運動目標的圖像塊;求出運動目標圖像塊的形心作為運動目標的中心,以此中心為端點,向四周發散出角度間隔為的n條射線,射線的另一端終止於圖像的邊緣;在每條射線上按照一定的準則(點的梯度和與目標中心的距離在一定閾值范圍內)找出n個初始輪廓點;以這些初始輪廓點作為主動輪廓模型( snake )的初始點,用改進的貪婪演算法使snake收斂到待分割的運動目標輪廓上。You can use them to schedule events that should occur at regular intervals after the initial run, with the period specifying the interval
可以用它們對那些初次運行之後需要按照常規間隔發生的事件進行調度,使用周期參數指定時間間隔。To the left of the dot was an entire face. when the words to the left were spaced normally and the face was of normal proportions, subjects had a great deal of difficulty identifying out of their peripheral vision the letter and the characteristics of the lips
研究發現,當組成黑點左邊單詞的字母間隔正常,或一整張面孔呈標準比例時,參與調查者很難從他們的周圍視覺對字母或是嘴唇的特徵進行識別。分享友人
