Transmittance 指光或其他辐射通过介质时的透射比例,常用于光学和化学领域,表示透明性或传递效率。

用法要点

句型搭配

Transmittance 通常作为名词使用,在句子中作主语或宾语,常与测量、计算或描述光学性质的动词搭配。

• The transmittance of the glass is high.
• We measured the transmittance at different wavelengths.
• Transmittance decreases with thickness.

介词用法

Transmittance 常与介词 of 连用,表示某物的透射率;也可用 at 指定波长或条件,或用 through 强调通过介质。

• transmittance of light
• transmittance at 500 nm
• transmittance through the filter

语域说明

Transmittance 是专业术语,主要用于科学、工程和技术语境,如光学、化学、材料科学,日常对话中较少使用。

• In optics, transmittance is a key parameter.
• The report includes transmittance data.
• High transmittance is essential for lenses.

基础例句

The transmittance of this window glass is very good, so it lets in a lot of sunlight.

这扇窗户玻璃的透光度很好,因此能透进大量阳光。

We checked the transmittance of the sunglasses to see how much UV they block.

我们检查了太阳镜的透射比,看看它们能阻挡多少紫外线。

High transmittance means the material is more transparent and lets light pass through easily.

高透射比意味着材料更透明,光线能轻松通过。

高级例句

In the experiment, we calculated the transmittance of the sample at various wavelengths to analyze its optical properties.

在实验中,我们计算了样品在不同波长下的透射比,以分析其光学特性。

The technical report highlights the transmittance values for the new coating, which show a 95% efficiency in visible light transmission.

技术报告强调了新涂层的透射比值,显示在可见光传输中效率达95%。

Transmittance measurements are crucial in quality control for optical components, ensuring they meet industry standards.

透射比测量在光学元件的质量控制中至关重要,确保它们符合行业标准。

常见错误

❌ 错误:The transmittance is high for the light.
✓ 正确:The transmittance of light is high.

错误在于介词使用不当,transmittance 通常与 of 连用表示某物的透射率,而不是 for。

❌ 错误:This glass has a good transmittance.
✓ 正确:This glass has high transmittance.

错误在于形容词搭配不自然,transmittance 常用 high 或 low 描述,而不是 good 或 bad,以更准确地表示数值高低。

近义词辨析

transparency

Transparency 更侧重于材料的透明或清晰程度,常用于日常或描述性语境;而 transmittance 是量化术语,指光通过的比例,多用于科学测量。

The transparency of the water allows us to see the bottom clearly, but we need to measure its transmittance for scientific analysis.

transmission

Transmission 泛指传递或传输过程,可用于光、信号、数据等;transmittance 特指透射的比例或系数,是 transmission 的一个量化指标。

The transmission of data through the network is fast, but the transmittance of light through the filter is only 80%.
