1.In this paper we introduced the developments in dentrite studies mainly including two fields: dentrite morphology and dentritic growth theory.

1.本文主要介绍了枝晶发展现状,主要包括枝晶形貌和长理论两个方面。

2.Porosity can be caused by gases coming out of solution during cooling and becoming trapped between dentrite arms as tiny voids.

2.在冷却过程，气体逸出造成多孔性，或被截留在晶体枝杈之间形成微小气孔。
