解釋
理想密度-
In this paper, the effects of fly ash, cement, lime, fine sands, foam agent, w / c ratio and additional agent on foamed concrete were studied by experiments, the best combination ratio of fly ash foamed concrete whose density varies from 551kg / m3 to 650kg / m3 was obtained through orthogonal test design, the foam agent quantity and the fly ash quantity effect the fly ash foamed concrete greatly, so the author selected them as independents to establish duality linear regression equations, the equations were quite ideal through the test of model summary r. moreover, the author also did some experiments about the water resistance of magnesium oxychloride cement fly ash foamed concrete, the outcome showed that phosphoric acid has good effect on water resistance, and its appropriate quantity was found
本文通過試驗研究了粉煤灰、水泥、石灰、細砂、發泡液、水灰比及外加劑對粉煤灰發泡混凝土性能的影響，採用正交設計試驗方法得出了600級粉煤灰發泡混凝土的最佳配合比，同時發現發泡液和粉煤灰摻量對發泡混凝土的影響最為顯著，因此，以二者為自變量建立了二元線性回歸方程，通過全相關系數的檢驗發現方程較為理想。此外，還對氯氧鎂水泥基粉煤灰發泡混凝土的耐水性進行了相關實驗，發現磷酸有較好的耐水性效果，同時找到了其合適的摻量范圍。 -

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。 -
