It's because it's a nice combination of softness, durability, and availability, the ancient Romans and Greeks use lead in practically everything from their plumbing and eating utensils, to their writing tablets.

这是因为它很好地综合了柔软性、耐性和可得性，古罗马人和古希腊人几乎处处上铅，从水管、餐具，到字板，有铅的身影。

The result is a mix of shops, entertainment venues, food courts, games arcades and gathering places that replicates the 20th-century American mall in digital form, and hybrid links of the virtual with the physical.

结果就形成了一个商店、娱乐场馆、美食广场、游戏厅和聚会地的综合体——以数字形式复制了20世纪的美国购物中心——以及连接虚拟与实体空间的混合链路。
