In different in terne die travel, the metal flow characterize in warm extrusion forming processes and the affection for the flow of metal stage which made by the difference between the blank bottom altitude and the axial direction limiting size in warm extrusion forming technique have been analysed we have gotten the equivalent strain field and the velocity field and other field variable that the blank in different in terne die travel and the die travel - load curve. at the same time, we have analyzed the contributing factor for the oil pump stator forming process optimized and achieve thereasonable die parameter for the war m extrusion forming finally, the optimized technics parameters were used into pilot production, then the qualified oil pump stator forging were produced, the analog results were compared with those of pilot production
論文具體分析研究了不同成形工藝過程中金屬流動的特點，並對不同凸模行程下溫擠成形過程中的金屬流動特點、坯料連皮厚度（底部高度）與溫擠壓成形工藝中的軸向界限尺寸的差值對金屬變形階段的影響進行了分析，獲得了坯料在不同凸模行程下的等效應變場、速度場等場變量及凸模行程-載荷曲線，同時對油泵定子成形過程的影響因素等進行了分析，優化並獲得了合理的溫擠成形工藝及模具參數。最後，利用模擬優化獲得的各項工藝參數進行生產實驗，得到實際生產出的合格油泵定子件，並將模擬結果與生產實驗結果進行比較。 -
In 1980 ' s, a new economic field - eco - economics - births. it provides the direction of society developments the ecosystem economics thinks the economic system is the second stage system of ecosystem or sub - system of environment, emphasizing mankind social economic activities have to obey natural ecosystem regulation, limiting economic scale in the resources supply of ecosystem system and the ability of wastes modulation
生態經濟觀認為經濟系統是生態系統或環境的亞系統或子系統（ sub - system ） ，強調人類社會經濟活動必須服從自然生態規律，將經濟規模限制在生態系統的資源供給和廢棄物調節能力之內，以維護生態系統結構和功能的穩定性，從而保證人類社會的生命支持基礎和社會經濟的可持續發展。 -
The industrialization theories of agriculture country of peikang chang mostly appears on his doctoral dissertation, agriculture and industrialization, completed in 1945. this thesis deals with the theories on the book from seven aspects : 1, the scientific, special but integrate industrialization definition ; 2, the relation theories between agriculture and industry ; 3, the industrialization launching and limiting factor, 4, the industrialization ' s beginning, procedure, stage and speed ; 5, the adjustment and fluctuation of agricultural construction in course of industrialization ; 6, the f oreign trade and using of the foreign capital in course of industrialization ; 7, the relation theories of the agriculture country and industry country
張培剛的農業國工業化理論主要體現在他1945年完成的博士論文《農業與工業化》一書中。本文從七個方面概述了該書的主要理論： 1 、科學、獨特而全面的工業化內涵； 2 、農業與工業的相互依存關系理論； 3 、工業化的發動因素和限制因素； 4 、工業化的開始、程序、階段和速度； 5 、工業化進程中農業結構的調整與變動； 6 、工業化進程中的對外貿易和利用外資； 7 、農業國與工業國的關系理論。
