亚稳区 meaning in Chinese
metastable region
Examples
- The precipitation sequence is . - supersaturated solid solution - stoicheometric " phase - growth . with the increase of the composition there is more characteristic of non - classical nucleation and growth , and the order parameter values of critical ordered nucleus decrease . the precipitation sequence is : supersaturated solid solution - nonstoicheometric ordered phase - stoicheometric " phase - growth
随浓度增加，大部分亚稳区合金沉淀非经典形核长大的特征增强，有序相临界晶核序参数分布曲线降低，且分布更加平缓，沉淀序列为：过饱和固溶体非化学计量比有序相化学计量比相长大，非化学计量比有序相并非热力学意义上的亚稳相，研究工作明确了这一点。 - 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
首次发现，随着原子间相互作用势的增加，亚稳区合金中有序相的体积分数和颗粒密度有所增加，有序相的尺寸和形核率有所提高，有序相周围的无序基体浓度的降低有所加快，有序相内的成分序参数和长程序参数有所提高，即促进了原子簇聚过程和有序化程度。 - No incontinuous transition has been found at mean - field spinodal lines and the transition of precipitation mechanism transform gradually across the mean - field spinodal lines . precipitation mechanism at disordering instability line is non - classical nucleation and growth , similar to those in metastable region , and precipitation mechanism at ordering instability line is non - classical nucleation and growth , followed by spinodal decomposition , similar to those in instable region
在不同的区域，粗化有不同的表现形式:在亚稳区，与(形核)长大交叠;在失稳区，与失稳分解交叠;在过渡区，与长大和失稳分解混合机制交叠。
