一般情况下，要研究清楚分块光滑解等常见的弱解，我们必须研究光滑解尤其是全局光滑解的结构和性质，这是研究高维守恒律方程方程全局解的基础。但用以往的处理方法一般来说是很困难的。

Basing of summarizing the past research findings, the pager presents a viewpoint thatcarry on data sub-blocks with "separating" according to mineral spectroscopicCharacteristics, and decreases the relativity of inter-data and increases the workingspeed. After a method is applied to imaging, spectrometry data are separated bymasking it acceptant result, analyzing content is explicated and the affecting ofsurrounding data is removed.

本文在总结前人研究的基础上提出利用&Separating&思想进行数据分析，对数据按照矿物光谱特征进行分块处理，以此来减少数据间的相关性，提高处理速度；对一种方法处理后的数据进行分离，掩膜结果以外的数据，明确处理的方向，消除周边数据可能带来的影响。

We presented a novel approach for empty space skipping for object-order volume rendering. A two-staged space skipping was introduced: the first stage applied bricking on a regular grid, and the second stage used octree to reach a finer granularity.

提出一种针对物体空间为序体绘制的空域跳过算法：采用双层次空间跳过，先以规则的数据分块作粗略地跳过，再以八叉树获得更高粒度的优化。

Then, the relation between vibration and sound, the acoustic holography method, the indeterminacy and identifiability of BSS, the BSS algorithm are discussed in detail. Based on above researches, the dissertation is divided in following four sections. The first section investigates the BSS algorithm suitable to acoustic feature separation. The algorithm of the joint approximate diagonalization of eigen-matrices is proposed. The spectra or the time-frequency distributions of source signals are the interesting features in ABD and they are separated from mixing signals by JADE algorithm. Then, the convolutive mixing model is transformed into a high-dimension instantaneous mixing model, and the deconvolution of source signals is achieved by the joint approximate block diagonalization of eigen-matrices. The proposed algorithm has a global minimum, and it is unsensitive to noise interference.

论文首先概述国内外声学诊断研究进展与盲分离研究进展，给出机器噪声声场与盲分离的数学描述，讨论了声振辐射、声全息、盲分离模型、盲分离可解性、盲分离结果不确定性、分离算法等基本问题，在此基础上，论文的研究工作分为以下四个部分：第一部分研究适用于声学特征分离的盲分离算法，提出基于特征提取的联合近似对角化盲分离算法，该算法以频谱特征或时频特征作为分离目标，从混合信号中分离源信号频谱特征或时频特征，最大限度地保留了与声学特征提取有关的频谱特征或时频特征，采用模型变换把卷积混合模型变换为一个高维瞬时混合模型，通过联合近似分块对角化算法实现源信号频谱特征与时频特征的盲反卷积。

At the same time, when we generate TIN, we must project the spatial points to the plane and every point can't overlap each other. So we also must generate TIN dividually then merge them into the whole skull's DSM.
