the isotropy of [noun]
The isotropy of the cosmic microwave background supports the Big Bang theory.
宇宙微波背景的各向同性支持了大爆炸理论。
各向同性
在所有方向上相同或具有相同物理性质的特性。；[化] 各向同性现象
the property of being isotropic; having the same value when measured in different directions
在所有方向上相同或具有相同物理性质的特性。
The property of being identical, or having the same physical properties, in all directions.
The isotropy of the material means its strength is the same in every direction.
材料的各向同性意味着其强度在各个方向上都相同。
用法提示：isotropy 为名词，表示‘各向同性’，指材料在各个方向上性质相同。
Physicists often test for isotropy by measuring a property along different axes.
物理学家常常通过沿不同轴测量某个性质来检验各向同性。
用法提示：isotropy 是名词，作介词 for 的宾语，指‘各向同性’。
The glass showed perfect isotropy, so light traveled through it at the same speed in all directions.

易错句子Isotropy means the material has different properties in different directions.
正确表达Isotropy means the material has the same properties in all directions.
混淆了isotropy（各向同性）与anisotropy（各向异性）的含义。isotropy指在不同方向上性质相同，而非不同。
anisotropy（各向异性）与 isotropy（各向同性）是相反的性质，前者指不同方向测量值不同。
isotropic（形容词）与 isotropy（名词）词性不同，isotropic 用于描述具有各向同性的物体或介质。
