The result of orthogonal experiment and secondary regression experiment on the bionic disk plows indicates that the bionic non - smooth partial sphere structure cell can decrease resistance by almost 30 % than common plow in the condition that the structure and distribution combine rationally. therefore, the bionic design and experiment research on disk plows is very significant
仿生圓盤犁刀的正交試驗和二次回歸試驗結果分析表明，如果圓盤犁刀的仿生非光滑
球冠結構單元的結構參數和分佈組合搭配合理，仿生圓盤犁比普通圓盤犁可減少阻力約30 ，因而本文對圓盤犁刀進行仿生設計與試驗研究是非常有意義的。
On the base of the basic structure study of the tooth - locked quick closure vessel of middle and low pressure with crown head, the optimization method of parameterized whole device is presented in this paper, the emphases of research is put on optimization of the tooth - locked quick closure device whose structure and load distribution is complicated, the wall of vessel, however, is designed according to the existing strength formula

球冠形封頭的中、低壓齒嚙式快開容器的基本結構進行研究的基礎上，提出了齒嚙式快開容器的參數化整體優化方法，研究重點放在結構和受力復雜的齒嚙式快開裝置的優化，對于容器簡體壁厚仍採用現有強度公式設計。
Secondly, two groups of disk plows for experiments were manufacturing. finally, orthogonal experiments and secondary regression experiments were respectively designed on the plows and tillage experiment was carried out in an indoor groove under certain research condition. with experimental optimum technology, the effect of the distribution of the geometric non - smooth partial sphere structure cell, partial sphere height and its radium on the tillage resistance was analyzed
