The difference between vector graphics and raster graphics, therefore, is that vector graphics are not translated into bit maps until the last possible moment, after all sizes and resolutions have been specified.

矢量图和位图的不同导致在所有尺寸和像素被确定后，不到最后一刻，矢量图不会被转换成位图。

The Laplacian matrix of G is the difference of degree matrix of G and the adjacent matrix of G, And the Laplacian spectral radius of a graph is the maximum eigenvalue of the Laplacian matrix of G.

图G的拉普拉斯矩阵为图G的度矩阵和它的邻接矩阵之差，而图G的拉普拉斯谱半径为图G的拉普拉斯矩阵绝对值最大的特征值。

After two experienced doctors of Traditional Chinese Medicine who knew nothing affirmed the pulse is wiry pulse, we used sphygmograph to note the sphygmogram of carotid. Then after the rabbits breathed calmly, two experienced doctors of Traditional Chinese Medicine who knew nothing affirmed the pulse was the normal pulse ,we noted the the sphygmogram of carotid under the same pulse-taking pressure. After classifying the parameters in the sphygmogram of carotid, we analyzed them by time domain.

2.2 给予家兔疼痛性刺激建立弦脉模型在非麻醉状态下将家兔行颈部手术，暴露颈动脉，经两名有经验的中医师双盲取脉，使用脉图仪记录颈动脉脉图，待家兔呼吸平稳后再由两名有经验的中医师双盲取脉，确认为平脉后在同样的取脉压力下记录颈动脉脉图，对脉图参数进行分类后做时域分析。

Methods 2.1 The experiment about changing electricic pressure values into the pulse-taking pressure values of making pressure standars of sphygmograph. Putting 1g、2g、5g、10g、20g、50g、100g、140g weights on the black1 probe and the black2 probe of NX-3 multifunctional sphygmograph ,putting 1g、2g、5g、10g、20g、50g weights on the purple probe of NX-3 multifunctional sphygmograph. Then we noted the the different pressure numerical value when putting none and different weights on the probes to prove the liner relationship between them. 2.2 Setting up wiry pulse model in achy rabbits We operated on the non-drugged state rabbits, exposure the carotid.

2.1 关于电学压力值与实际压力值换算的脉图仪压力定标实验：NX—3 多功能脉图仪黑色探头 1 和黑色探头 2 上放置 1g、2g、5g、10g、20g、50g、100g、140g砝码，NX—3 多功能脉图仪紫色探头放置 1g、2g、5g、10g、20g、50g 砝码分别记录两种脉图仪共三个探头其空载、探头上放置砝码时脉象采集仪上所显示的取脉压力值，验证砝码重与取脉压力值的线性关系。

The first stage is screen experiment. A 24-1 Fractional Factorial Design and resolution IV experiment is used to find out which main effect and interaction effect have obvious influence on the precision positioning of feeding table by these four factors. The Minitab program including Half Normal Plot, Pareto Chart, and ANOVA is applied to diagnose obvious effects. The second stage is optimization experiment. The fitness of regression model is obtained by using CCD of RSM with statistical hypothesis testing, regression analysis, lack-of-fit testing, and residual analysis. The optimum values can be found out by using response surface plot and contour plot.

However, Most vector-based algorithms of computing the Voronoi diagrams have difficulty while dealing with complex generators , and so author first discusses the properties of Voronoi diagram based on the Manhattan distance or supremum distance, the experimental result shows that Voronoi diagram based on the Manhattan distance or supremum distance or alternatively using these two distances is a rough approximation of Euclidean-metric Voronoi diagram.

鉴于构建Voronoi图的矢量方法存在一些问题及不足，首先分析了基于曼哈顿距离和上限距离的Voronoi图性质，进行了相应的实验，实验结果表明基于这两种距离或交替使用这两种距离所产生的Voronoi图与基于欧氏距离产生的Voronoi图之间存在较大的差异，属于精度较差的逼近方法。

The measurement takes account of accumulation of discrepancy signals, distribution of discrepancy signals, and treatment of preternatural discrepancy signals. Based on the measurement, this paper presents, at the same time, a new algorithm for extracting features with symmetric figure on scanned topographic map.

前者匹配效率高，稳定性好，对图象的非本质的变化不敏感；而后者利用图象中的所有信息，所以区分不同图象的能力强，精度高，特别是它能在十分复杂的图象环境下(此时很难甚至不可能使用特征匹配法)有效地工作。
