The results show that " the frame - pack rolling " technology can increase the densify, avoid cracking during rolling, and effectively improve the deformability and mechanical properties of the spray deposited porous aluminum alloy sheets
結果表明：外框限制軋制工藝提高了噴射沉積多孔材料的緻密度，避免了軋制過程中裂紋的形成，有效地改善了噴射沉積板坯的軋制性能及材料的力學性能。 -
So the effecte of frame - pack rolling technology on microstructure and mechanical proprties of spray deposited porous 5a06 and 8009 aluminum alloy sheets after rolling were studied
為此研究了外框限制軋制工藝對噴射沉積多孔材料5a06和8009鋁合金板坯軋制組織和力學性能的影響。 -
The definition, the essential, the orietation model and eleven kinds of functions of mes was dissertated in the article, the relation between mes and the plan layer and the control layer was deeply analysised, and the characteristic of mes in the industry application was researched in detail. after analysised the current production condition and the existent problem in jigang plate plant, the design of system frame, dadabase and function module have been studied, and the realization of it has been expounded. for solving the low efficiency in arranging the rolling plan by man, based on the traveling salesman problem and the pack problem about 0, 1, the mathematics model of the schedule of rolling plan was put forward, and the most near insert way was introduced to solve it, the result was satisfied. based on the practical demands of jigang plate plant combined the academic research of mes software, it has been realized the valid combination between the management of production scene and the upper management software in the dissertation
本文論述了mes的定義及其實質、 mes的定位模型和其十一項功能，深入分析它與計劃層和控制層的關系，並闡述了mes在行業應用中的特點。在分析濟鋼中厚板廠生產現狀及其存在的問題后，研究了系統的體系結構設計、數據庫設計和功能模塊設計，並對其實現進行了闡述。為了解決人工經驗編排軋製作業計劃問題的低效性，提出了基於旅行商問題和0 1背包問題的軋製作業計劃排序數學模型，並採用最近插入法進行求解，取得了滿意的效果。 -
Similarly, rolling back system object changes in a service pack only requires overwriting the current version of the resource
此復制方法也意味著回滾service pack所需的只是將當前版本的
