正本
Examples
- 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
全文共分为六个部分：第一部分是导言，主要阐述本文的研究对象、研究的主要内容、研究目的、研究的思路和方法及可能的创新之处。 - 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
希望通过分析土体受压后的变形特性和对沉降的原始数据处理与计算方法上的深入研究，以得出比传统的方法更加符合实际的地基沉降计算与预测方法。 - 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
但是标准mc算法存在较大的问题:标准mc算法实质上是通过阈值分割来提取等值面,阈值分割对某些医学图像的组织或器官的提取难以得到较好的效果;标准mc算法是逐个移动立方体来进行处理,就是说对所有的立方体都要进行一次检测,算法执行中30 % ~ 70 %的时间用在对空单元的检测上,因此需要有一种合理的数据结构对空间数据进行有效的遍历,以加速对空单元的检测和过滤;标准mc算法产生了大量的三角面片,一般重建的组织或器官包含数十万甚至上百万的三角面片,难以实现实时的绘制和交互操作;标准mc算法得到的表面网格并不光滑,会有一些不期望的凹凸,特别是在原始数据有较大误差的情况下尤其突出。
