世界上的物质可以是像桌子、椅子这样具有固定体积和形状的固体,也可以是像水、牛奶这样形状随着容器变化的液体,还可以是形状和体积都不固定的气体。温度的变化可以导致固体、液体和气体之间相互转化,如水可以转化为冰和水蒸气。那么,你见过既像固体、又像液体的奇妙物质吗?更奇妙的是,它的这种状态的转变不是通过温度变化,而是通过瞬时压力变化实现的。它就是殴不裂(英文名:oobleck)。
The substances in the world can be solids with a fixed volume and shape, such as tables and chairs. They can also be liquids that change in shape with water, milk, or other shapes and volumes. Changes in temperature can lead to the conversion of solids, liquids and gases into one another, as water can be converted into ice and water vapor. So, have you ever seen a fantastic substance that is both solid and fluid? Even more amazingly, its state of affairs is not transformed by temperature, but by instantaneous pressure changes. It is not cracked crack (English name: oobleck).
