所有入选者均行常规二维超声和组织多普勒超声心动图检查 3.1 常规二维超声心动图(two-dimensional echocardiography，2D)检查：采用胸骨旁左室长轴切面M型测量左室舒张末期前后径、右室舒张末期前后径、室间隔厚度、左室后壁厚度；心尖四腔、二腔切面面积勾画法分别测量左室、右室舒张末期容量和收缩末期容量并计算左室

In this time, we can recognize the number image depending on the location of the end-point. If the y-coordinate of the end-point is bigger than half of the height of the number image, the recognized result is 6. Else the result of recognition is 9. Then if there are two end-points and there is no trifurcate point, the possible recognition result of the number image is 2, 3, 5 or 7. Here, we need to recognize the number image by dint of the end-point directions and locations.

最后，我们根据特征提取的结果进行分类识别，如果没有端点、没有三叉点，则识别结果为0；如果无端点，两个三叉点，则识别结果为8；如果只有一个端点、一个三叉点，则识别结果可能为6或9，这时只需考虑端点的位置，即可将6和9区分开来；如果有两个端点、无三叉点，则识别结果可能为2、3、5、7，这时需要加入端点的位置和方向辅助判断。

By the combination of experimental results with theory of crystal growth, some growth models and growth mechanisms were proposed. Research results confirmed that pillar-shaped TaC whisker with spherical droplet at the end grew via a vapor-liquid-solid mechanism, pillar-shaped whisker with pyramid-like end was formed via a vapor-solid mechanism, awl-shaped TaC whisker with zigzag end formed via a liquid-solid mechanism, awl-shaped TaC whisker with growth step at the end has a growth mechanism of screw dislocation mechanism. The growth mechanism of dumbbell-shaped MgO nanowhisker and NaCl particle-decorated MgO nanowhisker is VS; C and MgO powder-yielded MgO nanowhisker was formed via a VLS mechanism, Mg powder-yielded MgO microwhisker and MgO microsized or nanosized crystal sheet grew via a VS mechanism. In the Si and SiO〓 nanostructures, Si nanowires formed in higher-temperature zone grew via oxide-assistant mechanism, while Si nanowires or nanorods formed in lower-temperature zone have a growth mechanism of VLS, and the growth mechanism of SiO〓 nanowires is VS.

研究确定呈平直柱状且头部带有球形颗粒的TaC晶须是通过气-液-固机制生长；头部呈之字型的锥状TaC晶须则通过液-固机制生长；晶须头部为四棱锥状的粗长TaC晶须的生长机制是VS机制；顶端呈锥状且有生长台阶的TaC晶须通过螺位错机制生长；哑铃状氧化镁晶须和氯化钠颗粒修饰的氧化镁纳米晶须的生长机制是气-固机制：当采用C+MgO粉提Mg源时形成的氧化镁纳米晶须的生长机制是VLS，而采用直接热蒸发Mg粉时得到的氧化镁微米晶须的生长机制为VS，纳米和微米晶片的生长机制均为VS机制；在高温区，硅纳米线的生长机制是助氧化机制，在低温区硅纳米线和纳米棒的生长机制是VLS机制，而氧化硅纳米线的生长中VS机制占主导地位。
