From parasternal long axis, LVDd and LVDs were measure by M-mode;From apex four chanmber view, EDV and ESV were measure by simplified Simpson method, LVEF was calculated, and by the pulse doppler of mitral and aortic valves, mitral valve diasolic flow E wave, A wave, ICT, IRT,and ET were measured.

AMI患者74例入院后行超声心动图检查，在胸骨旁长轴用M型测量LVDs，LVDd，心尖长轴切面用简化Simpson氏法测量EDV，ESV，并计算LVEF，多谱勒超声心动图采集测量二尖瓣和主动脉瓣血流频谱，测量二尖瓣舒张期血流E峰，A峰，ICT，IRT和ET，按公式计算Tei指教=/ET。

In this work,the volume data is encapsulated firstly and its logistic coordinate is defined,then the direction vector and the center of the cutting plane are calculated,the movement route of the plane is solved,specially a new sampling rule in cutting plane is presented.

该方法首先对体数据进行封装并定义逻辑坐标系，接着在逻辑坐标系中计算剖切平面的法向量和中心，求出平面的运动轨迹方程，并提出一种新的剖切面采样准则。

The representation of hatch area in technical drawing and machine drawing standards were discovered not limpid enough in the process of teaching practice and teaching material writing of machine drawing.

在机械制图的教学实践和机械制图教材的编写过程中，发现技术制图、机械制图标准在剖面区域的表示法不够清晰，相交剖切面后的结构的画法不方便画图以及断面图画法易产生异义等问题，并对此进行了分析，提出自己新的想法。

Aiming at the problem in the existing voxelization algorithms, a block-based algorithm is presented: GPU clipping method is used to voxelize the surface in every block, and ray intersection method is adopted to generate seeds filling the inner/outer space of blocks; among blocks, three seed planes are designed to help seeds span the blocks, so that a great deal computation for intersection is avoided.

提出以分块为基础的高分辨率实体体素化算法：在分块内部，采用基于图形处理器(Graphics Processing Unit， GPU)的切面光栅法对分块表面体素化过程进行加速，采用射线求交方式生成种子并进行块内填充；在分块之间，设计了3方向的种子扩散面及跨块扩散机制，避免因分块而导致的大量几何求交运算，提高了效率。
