Note to nerds: or possibly a lattice, narrowing toward the top; it's not the shape that matters here but the idea that there is at least a partial order.

对Nerd们的注解：可能是个格，顶尖；形状不重要，这里至少有个偏序关系。

Given a lattice symmetry, larger absolute photonic band gap was achieved by selecting an air hole shape of the same symmetry.

And in other side the lattice of the facade, built also with concrete and with a prefabricated shape of concrete which makes the building special.

另一方面，立面的格栅也是由预制的水泥模块建成的，使建筑显得独特。

Groups of those meshes are formed into a 3D shape, then seeded with cell cultures, which grow to fill in the lattice to create the final system.
