The quantitative phase-field simulations were reviewed on the processes of solidification of pure metals and alloys.The quantitative phase-field equations were treated in a diffuse thin-interface limit,which enabled the quantitative links between interface dynamics and model parameters in the quasi-equilibrium simulations.As a result,the quantitative modeling is more effective in dealing with microstructural pattern formation in the large scale simulations without any spurious kinetic effects.The development of the quantitative phase-field models in modeling the formation of microstructures such as dendritic structures,eutectic lamellas,seaweed morphologies,and grain boundaries in different solidified conditions was also reviewed with the purpose of guiding to find the new prospect of applications in the quantitative phase-field simulations.

“洗碗机买什么好?”当这个问题替代了“洗碗机能不能洗干净”,成为了消费端的新疑问时,这也意味着洗碗机品类经过十几年的市场教育,终于进入了普及阶段。而近几年,洗碗机市场的发展态势更节节攀高,国内消费者越来越接受这一“洗碗神器”。  过去作为“舶来品“针对西方饮食习惯的洗“碟”机,并不能很好的契合国内重油污、餐具形态复杂的情况。但是当下,越来越多的洗碗机品牌正在撕下“舶来品”的标签,向着适用、实用的中
