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 通過對1994年以來我國創業投資階段分布不均衡性的實證分析,引入期望吻合度函數來解釋該現象的形成機理,指出創業投資階段分布不均衡性將容易弱化創業投資孵化高技術產業的產業培育功能、加劇與傳統投資方式的不公平競爭、催生或助長經濟泡沫和泡沫經濟的形成。

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 本課題根據上述理論,利用有限元數值模擬仿真軟件deform - 3d ,對轉向油泵定子溫擠成形工藝過程進行模擬仿真分析,優化了油泵定子的成形工藝及模具參數。

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 由于轉向油泵定子的內部形狀復雜,零件壁厚分布不均,金屬流動規律難于掌握,目前人們對這種非均勻壁厚鍛件的溫擠壓成形工藝研究幾乎沒有,其成形工藝及生產用模具結構并未達到最優化。

At the same time , in the field of warm extrusion forming technique for pockety wall thickness forging , the research conclusion of this paper has important leading meaning and application value 同時,本論文的研究成果對非均勻壁厚鍛件的溫擠壓成形工藝研究有重要的指導意義及實用價值。

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 改進的鹽和胡椒濾波器可應用于灰度筆跡圖像,對于分布廣泛且不均勻的噪聲點的去除有較好的效果。
