物质属性

规则的厚度

Material has varying x & y dimensions (measured in dp) and a uniform thickness (1dp).

阴影应该脱离物体本身，而不是一直接近物体本身

Shadows depict the relative elevation between material elements.

Shadows are never approximated by coloring material.

内容不增加材料厚度

Content is displayed on material, in any shape and color. Content does not add thickness to material.

内容可以独立于材料而产生行为，但要在材料的范围内活动

Content can behave independently of the material, but is limited within the bounds of the material.

材料是固体，输入时间不能通过材料的边界

Input events cannot pass through material.

多个材料元素不能同时占据一个空间点

Multiple material elements cannot occupy the same point in space simultaneously.

材料不能穿过其他的材料

Material cannot pass through other material.

材料可以改变形状

Material can change shape.

材料只在其平面变化或者减少

Material grows and shrinks only along its plane.

材料不要弯曲或者折叠

Material never bends or folds.

两个材料可以合并，可以分解

Sheets of material can join together to become a single sheet of material.

材料可分解，可重组，可治愈

When split, material can heal. For example, if you remove a portion of material from a sheet of material, the sheet of material will become a whole sheet again.
