It is firstly found that for alloys in metastable region, with enhancement of atomic interaction energy, volume fraction and density of " phase particulate are increased, size and nucle ' ation rate of ordered phase raised, decline pace of composition in disordered matrix around the order phase is accelerated, composition order parameter and long range order parameter of ordered phase increased, i. e. process of clustering and ordering are accelerated
首次發現，隨著原子間相互作用勢的增加，亞穩區合金中有序相的體積分數和顆粒密度有所增加，有序相的尺寸和形核率有所提高，有序相周圍的無序基體濃度的降低有所加快，有序相內的成分序參數和長程序參數有所提高，即促進了原子簇聚過程和有序化程度。 -
Firstly, based on the present research all over the world, a 3d quasi - single phase model is built together with k - equations. the special feature of this model is taking account of the influence of interaction between liquid and gas, that is to say, the influence of interphase drag force, lifting force perpendicular to the relative velocity, virtual mass force and gas or liquid volume fraction in the fluid field have been considered. a 3d two - fluid model is also built in order to describe more accurately the fluid flow on distillation trays by comparing the computational results of quasi - single phase mathematical model with of two - fluid mathematical model
本文在國內外已有的研究基礎上，首先建立了以k - （封閉模型為基礎的三維擬單相流模型，該模型的特點在於充分考慮了氣液兩相間相互作用的影響，即計入了相間曳力、橫向升力、虛擬質量力和氣、液相含率對流場的影響；並建立了塔板三維雙流體模型，主要目的是通過對比擬單相流數學模型、雙流體數學模型的計算結果，建立能夠準確描述塔板上流體流動的數學模型。 -
