Total process of phase separation contains two stages that are the firstly fluctuating stage and the secondly diffusing stage.
分相有两种机理,即形核生长机理和 Spinodal 机理,而具体的分相过程又可分为两个阶段,即开始的波动阶段和随后的扩散阶段。
It\'s proved that in the loose stage local elastic deformation occurred which fitted linear equation,in the interim stage overall deformation occurred which fitted exponential equation and in the pressing stage plastic deformation occurred which fitted linear equation.
采用电子万能试验机和自制的实验装置,进行3种秸秆颗粒冷态压缩成型的开式实验研究,将其压缩成型特性曲线定义为松散、过渡、压紧和推移4个阶段,并对前3个阶段进行了回归分析,结果表明:在松散阶段,物料发生了局部弹性变形,其数学模型为线性方程;在过渡阶段,物料主要发生了弹性变形,其数学模型为指数方程;在压紧阶段,物料主要发生了塑性变形,该阶段的数学模型为线性方程。
This paper firstly adopts A* heuristic optimization algorithm to study the partition evacuation in public places with people's position fixing through translating partition evacuation into allocation problem.
通过将分区疏散转化为分配问题(Allocation Problem),并采用启发式的A*优化算法,对人员位置固定的公共场所分区疏散进行研究。
