與傳統的機械陀螺和光學陀螺相比,半球諧振陀螺具有如下優勢:結構上無高速轉子、無活動部件;不需預熱,啟動時間短;信號頻帶寬,漂移噪聲低;能承受大的機動過載;抗核輻射,並可經受短時間電源中斷的影響;體積小,重量輕,功耗低,壽命長,非常適合空間應用。Every room is equipped with adsl internet connection. the hotel also have the facilities of business center, conference rooms, shopping arcade, nightclub, ktv rooms, lounge bar, swimming pool, sauna center, chess room, beauty salon and otherrecreation activites on the beach. the resort is a famous tourist attraction with radiant and enchanting sunshine all year around, clean and blue sea - water, fine and soft sand, and green coconut trees dancing to the seaside breeze
酒店建築面積為二萬多平方米,背山面海,共有山海房200間套,所有房間均帶陽臺落地玻璃窗戶設計提供免費無限時寬帶上網介面,樓體結構一字排開,海景房觀海效果為180度震撼型超級無敵海景,與沙灘無任何隔離帶,零距離接觸大海。In the terms of interpolation, the image reconstructed from nearest interpolation or linear interpolation has good edge but serious noise ; reconstruction from 4 * 4cubic interpolation or three b - spline or three - order lagrange interpolations has better local character. 2 x 2cubic interpolations which has both better edge and local character is the ideal interpolation, the following is the basic principle during reconstruction : ( 1 ) the more width of interpolation, the more number of summation and the more order of interpolation polynomial, the higher of density resolution ; ( 2 ) the more of interpolation polynomial and width of interpolation, the more of reconstruction time simultaneously, aimed at eliminating the effects of noise contained in projection data, in this paper, author analysis cause and effects of common artifacts. importantly, discusses convolution back - projection reconstruction algorithm with a shift axis of rotation has been derived for correcting images that acquired with a divergence axis of rotation using the fan beam geometry with an angle - equaled detector
在ct圖像重建時,選擇有限帶寬窗有較好的空間解析度,三角形窗有較好的密度解析度,選擇餘弦窗則使得空間解析度與密度解析度的折衷;從窗函數的頻譜角度來講,可以用於圖像重建的一個良好的卷積窗函數應該具備以下條件: ( ? )小的3db帶寬b ,即最小的主瓣寬度; ( ? )最小的旁瓣最大峰值a ; ( ? )最大的旁瓣峰值衰減速度d ;就內插函數而言,臨近點內插與線性內插重建圖像噪聲大,但有較好的邊緣與細節; 4 4三次內插、三次b -樣條與四次拉格朗日多項式內插圖像平滑,局部特性較好。The joint transform correlator ( jtc ) is paid more attention by researchers than the matched filtering correlator ( mfc ) with its advantages, such as high spatial bandwidth product, without integrated filtering and real - time operation etc. photorefractive crystals have some advantages, such as fast response, high spatial resolution and large storage capacity etc. we can exert both advantages by combining the photorefractive crystal with the jtc
與匹配濾波相關器相比,聯合變換相關器具有諸多優點,如空間帶寬積高、無需濾波綜合、易於實時操作等,所以近年來更加引起人們的研究興趣。光折變晶體具有響應速度快、空間解析度高、存儲容量大等優點。將光折變晶體與聯合變換相關器相結合構成光折變聯合變換相關器,就可以充分發揮二者的優勢。Based on the acoustic energy flow detection, the spatial energy flow suppression can obtain time - space gain in direct proportion to time - bandwidth product, which is just the main advantage of the vector transducer
