不稳定线
不稳度线

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。
