Sequentially, the author discussed the technologies of medical image 3d visualization according to the clinical applications. with the development of computer, 3d visualization and computer graphics, the 3d visualization of medical images has progressed from fourier transform and convolve inverse projection to mpr ( multi - planar reformation, mpr ) and mtp ( maximum intensity projection, mtp ), nowadays, the real 3d reconstruction method, surface and volume rendering has risen. the image registering, image segmentation, pixel data set construction and 3d special interpolation are the key technologies in medical images 3d reconstruction
隨著計算機技術、三維可視化理論和計算機圖形學的發展，醫學圖像的三維可視化技術也從傅立葉變換、卷積反投影等基本圖像處理演算法，發展到真正的三維重建演算法：面繪制和體繪制；醫學圖像的三維可視化技術的應用也從三維醫學成像發展到虛擬內窺鏡，以及今天的虛擬可視化人體研究；而圖像的配準、圖像分割、體數據集的構建、三維空間插值則是醫學圖像三維可視化實現過程中的關鍵技術環節。The subject inducts digital time division technology ( pwm ), which is more advantageous at the accuracy and the predigest of hardware than simulant multiplication. what they call measuring power energy reasonably is that measuting except harmonics power energy fed back power. yet it realizes reasonable measurement of power energy which measures by base wave ac parameters method base on digital time division
本課題引入了數字時分割（ pwm ）脈寬調制技術，在測量的準確性、硬體電路的簡化等方面都比模擬乘法器具有較高的優越性。所謂合理的計量電能，就是不計非線性負載回饋給電網的負的諧波電能，而採用基於數字時分割的基波交流參數測量的方法，真正實現了電能的合理計量。The focus of the thesis lies in an elaboration of the influences exerted upon a listed company ' s profit return by the monopolist position the state - owned shares occupy, by the degree to which share - right is concentrated, and by the division of non - negotiable shares and negotiable shares, as well as of the positive promotion to the company ' s profit return by the system of executives buying - back shares and employees " share - ownership. based on theoretical analysis and case study, the thesis proposes some measures for optimizing the share - right composition and enhancing the profit return of the listed companies. the conclusion can be summed up as follows : ( 1 ) owing to the absence of real trustor, the unduly long, hence low, efficiency of the agency chain, state - owned shares are prone to being controlled by insiders and to the problem of share - holders " interests being embezzled by insiders
基本的分析結論可以概括為如下幾點： （一）國有股由於真正的委託人缺位，代理鏈條過長，代理效率低下，容易產生內部人控制，並發生內部人侵佔股東利益的問題，法人股在公司治理中的效率明顯優于國有股，因此，如何完善國有資產管理體制是優化股權結構的關鍵，本文提出了完善國有資產管理體制的具體建議； （二）在非流通股與流通股並存的股權分割下，非流通股股東與流通股股東具有不同的目標函數，非流通股股東的目標函數是提高每股凈資產，而流通股的目標函數是股票的二級市場價格，目標函數的不一致，導致股東之間行為的不一致，相互沖突的行為造成效率的損失。
