This dissertation expands on a new algorithm, which has the function of analyzing edge form with the chain code. By the introduction of the concepts of relative chain code and absolute chain code, we proposed a simple and direct algorithm to compute chain code sum(average chain code). We found that tangent direction(slope) of edge point can be figured by the absolute chain code sum of three sequential points and curvature of edge can be figured by the difference of chain code sum between the three sequential points ingoing and outgoing. Furthermore, we provided the criterion distinguishing edge inflexion and sleek curve section and the method computing inaccurately curvature radius and approximate perimeter. In the end of the paper, we introduced the use method with cell edge hollow repairing and overlap or conglutination cell segmenting for example. This algorithm has proved high speed and has a good effect of cell segmention on more than twenty groups of conglutinate and absent cells which are gathered from three kinds of cells.

This study determines a boundary shape of shaker's skeleton with the method of boundary shapes analysis.The skeleton's shape is optimized to achieve the required the first natural frequency.The result shows this approach is feasible and efficient and avoids the distortion of mesh resulting from great changes in structure.And it not only improves the shaker's max frequency,but also reduces the additional mass effect of the shaker on the evaluated object.

采用分析边界形状法来描述激振器骨架的边界形状,以骨架一阶固有频率满足期望值为目标建立数学模型,对骨架进行了形状优化。结果表明此法实际可行,具有较高的效率,避免了结构大变形时网格产生畸变;同时采用优化后骨架的激振器,不仅拓宽了使用频宽的上限,而且减小了对被测试件附加质量的影响。
