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。 -
Under no excess pbo flux environment, the perovskite phase of pmnt single crystals were more stable than that of pznt, but it was found to be the decomposition of perovskite crystals into pyrochlore crystals at 1250. the pure perovskite pznt crystals prepared by the pbo flux method were thermodynamically metastable
在無pbo條件下pmnt晶體較pznt晶體穩定，但在1250附近的高溫下會發生向焦綠石相的分解反應； pznt單晶體是亞穩定的，在高溫時亦分解生成焦綠石相和pbo 。 -
The study showed that the effect of surface tension induced by the nanosize curvature of critical nuclei could drive metastable phase region of diamond nucleation in carbon diagram into stable phase region, consequently, for both of homogenous and heterogeneous nucleation processes, diamond nucleation would be prior to graphite nucleation in competing growth of diamond and graphite upon chemical vapor deposition ( cvd )
研究表明，建立在碳的平衡相圖基礎上，在納米尺寸的金剛石臨界核的曲率誘導下的表面張力效應將金剛石成核的亞穩相區推進到穩定相區，因此無論對于金剛石的均勻氣相成核還是異質成核，在金剛石和石墨的競爭生長中，金剛石成核均優先於石墨成核。 -
Alloy fabricated by arc melting consists of continuous nbssi matrix and dispersive distributed nb particles. the metastable nbasi phase is found to have a tetragonal crystal structure with space group p42 / n and lattice parameters a = 1. 021nm, c = 0. 519nm
O 0 ）金屬間化合物的顯微組織由連續的nb3si基體、彌散分佈的nb粒子組成，其中亞穩態相nb3si為四方結構，空間群p42 n ，點陣常數a l -
The metastable austenitic phase of s s fiber at the interface of the fiber / cu composite would turn back to equilibrium with the interfacial energy and inter stain inducing, when the cu films were separated from s s fiber. so the magnetism value of the s s fiber declined. the information of grain - orientation at the interface of the fiber / cu composite can serve as a mechanism responsible for its declining coercivity, and a part of cu elements diffused into s s fibers
不銹鋼纖維銅復合體去除銅層后，原有的界面能及應力下降，使得原纖維界面處弱磁性的部分亞穩奧氏體，恢復到平衡態，它們對樣品s測試結果不再有貢獻；不銹鋼纖維銅復合體中，處于界面處的纖維晶粒具有很強的軸向取向排列，當晶粒取向性減弱，磁疇轉動的阻力增加，磁體的矯頑力上升。 -
The sequence is : non - classical ng supersaturated solid solution spinodal decomposition the variation in precipitation mechanism of 8 " phase in intermediate region is systematically investigated firstly, and it is found that with the increase of composition the precipitation characteristic transforms from that of metastable to instable region gradually
首次發現l12有序疇之間首先形成較寬的重合位置點陣，隨時間延續，重合位置點陣逐漸向ll :結構轉變，在兩有序疇之間形成反相疇界，隨后，由於合金發生分解，反相疇界被有序一無序界面替代。 -
During the present research of the flow characteristics of refrigerant in adiabatic capillary tubes, a drift flux model of two - phase flow was established and the influence of metastable phenomenon was considered. the flow characteristics of refrigerant were analyzed with the program developed in this research. an experimental system for the adiabatic capillary tubes testing was set up. the results show that the theoretical model fits the experimental data well
在對絕熱毛細管內製冷劑的流動特性進行研究的過程中，運用兩相流漂移模型，並考慮製冷劑在實際流動中存在的亞穩態，開發了絕熱毛細管內製冷劑兩相流的數值計算程序，對毛細管內製冷劑的流動特性進行了分析;搭建了毛細管兩相流實驗裝置，並將計算結果與實驗數據進行比較，結果吻合的較好。
