oringinal 中文意思是什麼

The thesis is composed of six parts : part one, introduction, mainly elaborates the research objects, its content, purpose and its oringinal aspects as well as its thinking and approaches

全文共分為六個部分：第一部分是導言，主要闡述本文的研究對象、研究的主要內容、研究目的、研究的思路和方法及可能的創新之處。

In order to overcome the disadvantages of the traditional calculating method, many researchers of geotechnical engineering like to use other calculating methods and analyze the oringinal settlement data to predict the settlement. compared with the traditional calculating method, this method has the advantages of accuracy and convenience

希望通過分析土體受壓后的變形特性和對沉降的原始數據處理與計算方法上的深入研究，以得出比傳統的方法更加符合實際的地基沉降計算與預測方法。

But the standard mc has some shortcomings : firstly, the standard mc picks up isosurfaces by threshold, however, threshold segmentation is invalid for picking up tissues or organs from some medical images ; secondly, the standard mc pocesses cubes one by one, that is to say, all the cubes will be checked, and the algorithm spents 30 % - 70 % of time to check the null units, so we need a reasonable data structure to travel the space data and accelerate the checking or filting of null units ; thirdly, the standard mc has a large scale of triangles, normally, the tissue or organ reconstructed includes hundreds of thousands so much as millions of triangles, this means it hardly to execute real - time rendering or interaction ; lastly, the standard mc can not get the very smoothly surface mesh, and there will be some unexpected accidented cases, especially in the case of big errors in oringinal data

但是標準mc演算法存在較大的問題:標準mc演算法實質上是通過閾值分割來提取等值面，閾值分割對某些醫學圖像的組織或器官的提取難以得到較好的效果;標準mc演算法是逐個移動立方體來進行處理，就是說對所有的立方體都要進行一次檢測，演算法執行中30 % ~ 70 %的時間用在對空單元的檢測上，因此需要有一種合理的數據結構對空間數據進行有效的遍歷，以加速對空單元的檢測和過濾;標準mc演算法產生了大量的三角面片，一般重建的組織或器官包含數十萬甚至上百萬的三角面片，難以實現實時的繪制和交互操作;標準mc演算法得到的表面網格並不光滑，會有一些不期望的凹凸，特別是在原始數據有較大誤差的情況下尤其突出。
