坩堝移動式噴射沉積技術作為一種先進的材料制備新技術,在制備大尺寸合金及金屬基復合材料方面具有顯著的優越性。然而噴射沉積坯件特別是大型坯件通常存在一定量的孔隙,顆粒表面存在一定量的氧化膜,顆粒之間未能完全達到良好的冶金結合狀態,因此需要進行后續緻密化和塑性變形才能獲得理想的組織和性能。本文採用一種新型的楔形壓制工藝,即通過局部變形、多道次小變形累積實現大變形的緻密化加工方法,對噴射沉積多孔坯料進行后續緻密化和塑性變形,很好地解決了傳統加工工藝的難題,大大降低了生產成本。This is so because climbing plants are likely to encounter intensive - changing environmental condition during their growth ( especially change of illumination ). secondly, there is a large proportion ( 30 - 40 % ) of climbing plants which belong to dioecism, and hence a gap between male and female plants on morphology, biological characteristic, economic value and so on. this dissertation focuses on herbaceous climbing plants, perennial or annual species such as dioecious trchosahthes kirilowii maxin and dioscorea opposita thumb, and monoecious luffa cylindrical ( l ) roem, it attempts to discover how climbing plants adapted to various environments and the mechanism of adaptation from aspects of physiological and reproductive ecologies at present, due to overuse of chlorofluorocarbons ( cfcs ), the ozonosphere has become thinner and thinner, and the ultraviolet - b ( uv - b ) radiation has increased considerably
