  1. 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。
  2. Q vector divergence field submit piece form district of convergence and divergence, have reflected meso - scale character. in the interface of convergence district and divergence district of q vector divergence, accompany severe convection precipitation and convection precipitation strengthen following convergence center strength, weaken following divergence center weaken

    在對流層低層q矢量散度輻合區和輻散區的交界處,伴隨有較大的對流性降水,對流性降水的強度隨輻合中心強度的增強而增強,隨輻合中心強度的減弱而減弱。
  3. Using monthly mean rainfall and temperature data in north - west of china ( nwc ), the characteristics of rainfall anomaly at rainy season in nwc and the inter - annual varieties of drought / flood are diagnosed by means of eof, reof and wavelet analysis et al. and the ncep / ncar monthly reanalyzed data are employed to analyse the evolution character of water vapor flux and it ' s divergence flux, 500hpa height and u, v wind field. results show that ( a ) the space distribution of rainfall anomaly can be separated into seven climate sensitive areas, the first and the third region have the same rought / flood trend

    本文使用西北(區) 168個站1961 2000年6 9月(主汛期)月平均降水、溫度資料,運用eof 、 reof 、小波分析等方法診斷了主汛期月降水異常和旱澇的年代際變化;同時利用ncep ncar月平均資料,分析了強(弱)季風年西北空中水汽通量及其散度場、 500hpa高度場、 u 、 v風場的演變特徵,結果表明: ( a )西北汛期降水可分為七個氣候異常區,第一、三異常區旱澇趨勢相同。
  4. For better veracity of simulating model, model is used lookup - table module to calculate the thermodynamic character of refrigerant, and datas of experience and test is combined in the compressor module, also the coefficient of heat transfer changing by running parameter is decided by computational procedure. in addition, choosing congruence step size solves the divergence of simulation procedure

    為了使模擬模型具有相當的準確性,模型中採用查表模塊進行製冷劑熱力性質計算,壓縮機模塊中將實驗數據與經驗計算數據相結合,通過程序運算確定冷凝器和蒸發器傳熱系數與運行參數之間的關系,並成功解決了模擬程序運行發散的問題。
  5. The results show that the " 8. 11 " rainstorm had significant mesoscale character. ascending motion, divergence and vorticity field intensified rapidly in the narrow area of rainstorm
