Above this glass floor, a labyrinth of large-scale bookshelves interconnects through a series of metallic and glass walkways, rather than by solid floors.
Research on that metallic melts transforms from liquid to solid state based on heat transfer theory is an important discipline in casting solidification.
研究基于热传输理论的熔融金属从液体转变到固体状态变化过程是铸件凝固研究的重要分支。
