But all designed software before in our country still have some weakness, for example, the conventional type of cam counld be projected by these software is very little, and used approximation by lines to curves of cam which have bigger error and more nodal points that result in chattering of principal axis. in furthermore, this software of designing cam in fact only has the function of cad. if you want to simulate and work over the designed cam in that software, you will find that you have to export it to other cad / cam system software ( e
隨著數控加工在我國的深入開展，真正實現我國的凸輪cad cam就顯得非常必要，但以往的凸輪設計軟體還存在許多不足，如可設計的凸輪類型較少，大多集中於平面凸輪；且採用誤差較大、節點數過密的直線逼近法生成凸輪工作曲線，造成計算時間長，且加工中產生較大振動；同時這些凸輪設計軟體基本上只具有cad功能，如果想將設計好的凸輪進行模擬和加工，就必須將圖形輸出到其它通用cad cam軟體（如mastercam等）中，因此這些軟體在實際應用中總不盡人意。Non - generated gear
非展成大輪A new aerodynamic design system developed by authors for draft fan with enhanced efficiency, suppressed noise, enlarged flux and high load. the new design system features : a twist regulation for vortex control is employed in designing to lessen the secondary flow loss in the blade tip and hub ; the feasibility and high efficiency of this procedure has been verified by the tests of the prototype fan ; a new computer - aided 3d blading is used to optimize the blade ; numerical inverse checking is adopted to enhance accuracy in designing and cut down the period of the designing and production. this design system can make the optimized blade with " forward inclination ", " inclining sweep ", " bending sweep ", to minimize the various secondary flow losses, to expand the steady working range of the fan, and to suppress the aerodynamic noise source
本文通過對一種新型高性能礦用局部通風機的設計、製造及試驗全過程的綜述，展現了新的先進設計體系在民用通風機上的成功運用，其研製特點是： （ 1 ）在葉片氣動設計中為了降低葉根及葉尖區二次流損失，採用可控渦扭向規律設計，樣機實測的高性能驗證了這種方法的可行性和高效性； （ 2 ）在設計方法中採用較精確的數值反驗算，獲取最優設計方案，大大提高設計的準確性和成功率，並縮短了設計試制周期； （ 3 ）在設計過程中發展了計算機輔助三維葉片造型新方法，可以根據設計需要簡便快捷地對葉片進行「前傾」 、 「傾掠」或「彎掠」造型，這些造型對減小各種二次流損失、擴大穩定工況范圍和控制葉輪機氣動噪聲源起到了非常好的作用。Abstract : a new aerodynamic design system developed by authors for draft fan with enhanced efficiency, suppressed noise, enlarged flux and high load. the new design system features : a twist regulation for vortex control is employed in designing to lessen the secondary flow loss in the blade tip and hub ; the feasibility and high efficiency of this procedure has been verified by the tests of the prototype fan ; a new computer - aided 3d blading is used to optimize the blade ; numerical inverse checking is adopted to enhance accuracy in designing and cut down the period of the designing and production. this design system can make the optimized blade with " forward inclination ", " inclining sweep ", " bending sweep ", to minimize the various secondary flow losses, to expand the steady working range of the fan, and to suppress the aerodynamic noise source

為了對公司治理有一個更全面和深刻的認識，本文從公司治理的起源入手，力爭較為清晰地勾勒出公司治理理論產生、發展和整個理論體系最終形成的大致輪廓，並從新古典經濟學和交易成本經濟學關于企業性質的企業理論，制度經濟學關于企業控制權的企業理論，產權經濟學的企業產權理論，信息經濟學的非對稱信息理論等幾個方面，論述了這些對公司治理理論有著重要影響並構成其主要內容的理論基礎，進而就公司治理的基本理論，即，古典管家理論與現代管家理論，產權論與競爭論，委託代理理論以及利益相關者理論，做了一個簡單的介紹與評價。分享友人
