In this paper,the updated Snake model is used to solve the echocardiography processing.Based on the updated active contour model,the contour points for two-dimensional slice serial of echocardiography are gotten.On this basis,through calculating the distance between the contour points of each two-dimensional slice and the center axis lines,the distance matrix from the four cambers of the ventricle to the center plane of ventricle are gotten.And through interpolating,smooth handling and filtering,the 3D endoscopic surface of ventricle is fitted out.Besides,in the medical measurements field,the slice area of ventricle and the volume of ventricle are measured,and the trend of slice area is also analyzed.

将改进的Snake模型应用于心脏超声波图像处理：基于改进Snake模型的思想，得到了心脏超声波图像二维切片序列的轮廓点，在此基础上，得到分割出的心室上下左右4个曲面上轮廓点到中心平面的距离矩阵，并通过插值和平滑处理以及滤波处理工作，拟合出心室的三维曲面图，取得了较好的效果；在医学测量方面，对心室的切片面积、变化趋势及心室的体积进行了测量。

Comparing with the result of methyl iodide in intense laser field, some differences are observed:(1) at the same laser field intensity, the highest charged fragment ion of methyl bromide was Br(superscript 3+), lower than I(superscript 6+) of methyl iodide;(2) the dehydrogenation channel was observed in the multiphoton dissociation or Coulomb explosion of methyl bromide, but was not observed in the case of methyl iodide;(3) HBr(superscript +) was observed, but there was no similar channel in the case of methyl iodide;(4) for methyl bromide, the valid charge distance of Coulomb explosion increases with the product of p and q; while in the case of methyl iodide, the distance remained almost the same;(5) the producing channel of CH(superscript + subscript m)(m=0, 1, 2) is different from the ionization-dissociation of methyl iodide in which the stepwise dissociation of CH3(superscript +) was thought to be the main channel, CH(superscript + subscript m)(m=0, 1, 2) of methyl bromide are mainly from the products of the direct dissociation of the dehydrogenated parent ions instead of the stepwise dissociation of CH3(superscript +).

与碘甲烷在强场中的实验结果对比发现：(1)在相同的激光场强下，碘甲烷电离解离的最高价碎片离子为I(上标 6+)而溴甲烷为Br(上标 3+)；(2)溴甲烷质谱中存在母体离子的脱氢产物CHBr和CHBr(上标 2+)，而对于碘甲烷，没有检测到这些通道，C-I键首先断开；(3)质谱中存在H^79Br和H^81Br，而碘甲烷的电离解离中不存在HI产物；(4)溴甲烷库仑两体爆炸的有效电荷间距随着两碎片电荷乘积的增大而增大，而对于碘甲烷此间距几乎不随电荷乘积变化；(5)CH(m=0， 1， 2)的主要生成通道可能与碘甲烷不同，不是来自CH3的顺序脱氢，而是来自脱氢母体离子的直接解离。

Based on destroying the narrative distance and aesthetic distance of epics, Tom Jones overturned the syllable and rhyme of epics , belittled refined phraseology, while Ulysses further belittled words and carnivalized language. Meanwhile, by way of parodying various styles in history Ulysses strode across a new style which nobody else could imitate and surpass till now.

在破坏史诗的叙事距离和审美距离的基础上，《汤姆·琼斯》颠覆了史诗的音节格律，并对典雅用语脱冕，《尤利西斯》则进一步对词语脱冕，使语言狂欢化，并通过对历史上各种文体的讽拟，跨越进一种新的文体——使旁人至今无法模仿和超越的文体。

Aiming at the currently shortage of XML streams quality detecting, this paper proposes a new forecasting method of XML streams quality by least squares support vector machines, which is used the method of XML keys' vector matrix as windows, and vector product wavelet transform to multilevel decompose and refactor the XML streams series, that can fulfill real-time checking demand of XML quality, and ensure constraint, consist- ency and integrality. For even more adapting net load, it proposes a control strategy by weight and adaptive adjustment to ensure XML streams quality.
