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。Chapter three author aimming at the blank of study on the inrollment policy of the higher education for minorities tries to probe theoretically into it from the perspective of the cause of minority student achieveinent higher educational function and educational policy, and to define the essence principle and foundadion of this policy, firstly, auther wants to show that the root to implementing this policy bases on minority history earth instance and cultural speciality by analyzing the cause of minority students low achievement, secondly, by the perspective perspective of higher educational function, author tries to show the important role of higher education to socialize minority students in case they are peripheried, to inherit and improve minority culture, in order to define that this policy is an important political mechanism to safeguard minority " s educational right and educational equality, thirdly, there are two points to be showed by discussing with the perspective of educational policy : the inrollment policy of the higher education for minorities is complexity and it is restricted and influenced easily by correlative mechanism because it involves virtuely in educational problem ethical problem and policy problem, on the other hand, the inrollment policy of the higher education for minorities don " t violate the principle of individual equality, instead, it carries out certain policy for some groups basing on the principle of the individual equality
一、通過對少數民族學生低學業成就的歸因分析，論述少數民族高等教育招生政策實施依據是少數民族歷史發展、現實狀況和文化特殊性。二、通過高等教育功能視角的探討，論述高等教育對少數民族學生的進一步社會化，避免少數民族個體被邊緣化的意義，以及高等教育對少數民族繼承、發展民族文化的意義，明確少數民族高等教育招生政策是保障少數民族高等教育權利、保證教育公平的一項重要的「政治機制」 。三、通過教育政策視角的探討，主要有兩方面內容，一是由教育政策的特點，論述少數民族高等教育招生政策實質上是集教育問題、民族問題和政策問題於一身，這使它的運行具有復雜性，它更易受其它相關機制的制約和影響;二是通過教育政策價值取向的探討，論述少數民族高等教育招生政策雖以一定群體為實施的對象，但並不違背個體平等原則，它是立足於個體平等的基礎上，依據能力選拔的原則，針對群體差異客觀存在的現實，對一定群體實施的一定「優惠政策」 ，以保證處於弱勢地位群體的權利，從而真正實現個體的平等。Analyzed life - span issues of every content, characteristic of stage to project, carry on the concrete exposition to quality, cost, progress three major meaning of control goal that carry throughout project especially, prove project life - span issues of every stage and systematic ness of the three control goals. combine traditional project a great deal of drawbacks that management mode have, theory and management inherit foundation of thought analyses and carry on project life - span issues of integrated necessity and feasibility of management in system. from project management two level, four stage and three major angle of control goal these, synthesize integrated concept, model, train of thought and implementation method after putting forward project management
