In addition, the principle for increasing extrusion pressure and determining way for key parameters on each sub-zone was discussed. 通過(guò)深入分析，得出了個(gè)分區關(guān)鍵參數的設計準則與確定方法，探討了提高擠壓力的措施，最后通過(guò)與實(shí)驗結果的比較驗證了其工程應用價(jià)值。
On the principle of the deformation work this paper words out a very simple method for approximate calculation of the extrusion force in the metalic plastic extrusion processes. 運用變形功原理，推導出求金屬塑性擠壓過(guò)程中擠壓力的一種極其簡(jiǎn)捷的近似計算式。
