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

本文主要介绍了枝晶的发展现状,主要包括枝晶形貌两个方面。

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

在冷却过程中，溶液中的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。
