So the advanced salt and pepper filter is applied in the gray handwriting images . the best result is achieved in these handwriting images , which have the broad and pockety noise 改进的盐和胡椒滤波器可应用于灰度笔迹图像，对于分布广泛且不均匀的噪声点的去除有较好的效果。

The inside fashion of the sway oil pump stator is complex , its wall thickness is pockety and the metal flow law is difficult to master . at the present time , the investigation of warm extrusion forming technique for the nonuniform wall thickness forging has few to been done . the forming technique and die configuration which use for production have not achieve optimization 由于转向油泵定子的内部形状复杂，零件壁厚分布不均，金属流动规律难于掌握，目前人们对这种非均匀壁厚锻件的温挤压成形工艺研究几乎没有，其成形工艺及生产用模具结构并未达到最优化。

According to the above theories , with using the software - deform - 3d , we have made the numerical analog simulation and analyse the warm extrusion forming technique process for sway oil pump stator , optimized the forming : technique and the die parameter for the pockety wall thickness forging this paper concretely analysis and research metal flow ' s characterize in different forming processes 本课题根据上述理论，利用有限元数值模拟仿真软件deform - 3d ，对转向油泵定子温挤成形工艺过程进行模拟仿真分析，优化了油泵定子的成形工艺及模具参数。

On the basis of empirical analysis of chinese pockety distributing of venture capital on investment stages since 1994 , this article uses expectation inosculation function to explain the reason of that , and figures out that this phenomenon not merely easily lead to weakening the fostering function of the high - tech industry by venture capital , aggravating the unfair competition with the traditional way of investment , but also encouraging the emergence of economic foam and the bubble economy 通过对1994年以来我国创业投资阶段分布不均衡性的实证分析,引入期望吻合度函数来解释该现象的形成机理,指出创业投资阶段分布不均衡性将容易弱化创业投资孵化高技术产业的产业培育功能、加剧与传统投资方式的不公平竞争、催生或助长经济泡沫和泡沫经济的形成。
