transmittance of [substance/wavelength]
The transmittance of glass is over 90% for visible light.
玻璃对可见光的透射比超过90%。
透射率;透过率
传送;传递;传输;传递。;入射光或其他辐射透过物质的分数。;传递系数;透明性
传输;传递。
A transmission.
入射光或其他辐射透过物质的分数。
The fraction of incident light, or other radiation, that passes through a substance.
This glass has a high transmittance for visible light, so the room stays bright.
这种玻璃对可见光的透射率很高,所以房间保持明亮。
用法提示:此处 transmittance 为名词,表示光线透过物质的比率。
We measured the transmittance of the film at different wavelengths in the lab.
我们在实验室测量了薄膜在不同波长下的透射率。
用法提示:transmittance 作名词,指辐射穿过物质的分数。
These materials show different transmittances, which affects how much heat enters the building.
这些材料显示出不同的透射率,这会影响进入建筑物的热量多少。
用法提示:复数形式 transmittances 表示多种透射率,仍是名词。
The transmittance of glass is over 90% for visible light.
玻璃对可见光的透射比超过90%。
Materials with high transmittance are preferred for optical windows.

易错句子The material transmittances 90% of light.
正确表达The material has a transmittance of 90%.
“transmittance” 是名词,不能用作动词。正确用法是将其作为名词,用 “has a transmittance of” 结构表示“透射比为”。
grammar · medium
易错句子The transmittance of the signal was low.
正确表达The transmission of the signal was low.
“transmittance” 特指辐射能穿过物质的透射比,不用于信号或数据传输。表示信号传递应使用 “transmission”。
transmittance 指透射比率,而 transmission 指透射过程或传输行为
transmittance 是能量透过比率,transparency 指物质透明程度,常为定性描述
