The method for the point sets selection of point Hough transform and the scan direction for image of searching the point sets were improved by using the geometrical characteristic of the concentric circles:The center of the concentric circles was obtained in the accumulative array firstly,radius was obtained by the mean of distance between the circle center and every edge points afterwards,both the circle center and the edge of the concentric circles were detected accordingly.

利用同心圆的几何特点对点Hough变换边缘点的点组选取方法和搜索点组的图像扫描方向进行了改进：首先由累加阵列确定同心圆的圆心，然后由圆心到各个有效边缘点距离的均值求出半径，从而检测出同心圆的圆心与边缘。

When 2 events occur within a same focal region and the distance between 2 events is far shorter than the distance between events and the station, the ratio of observed spectral amplitudes of the direct P and S phases is linearly correlated with the ratio of their radiation pattern factors, and radiation pattern factors depend on geometrical property focal mechanisms.

发生在同一震源区的两个地震，当地震之间的距离远小于地震到台站之间的距离时，同一个台站的直达P波、S波零频观测谱值之比与其辐射图型因子之比线性相关，而辐射图型因子取决于震源机制解的几何特性。

RESULTS: Stent materials play an important role in reducing inflammatory reaction and restenosis following stent implantation. As a medical material for humans, the features of stent should be meet the requirements of reliable distensibility, mechanical persistence, good flexibility and geometrical stability, possible small diameter, excellent blood compatibility, as well as good corrosion resistance. All of these depended on the mechanical and physical features of materials.
