红外辐射

Such so-called Dyson spheres would, if they exist, reradiate captured energy (after some of it had been put to good use) as heat—infra-red radiation.

这样的中空球结构称为"Dyson球"。如果这样的外星生物存在，他们捕捉的能量在利用之后可能有再辐射，即热红外辐射。

The structure and the principle of pyroelectric infrared sensor was introduced,and the detail of key points in using the sensor was discussed.

引言红外辐射的物理本质是热辐射，它是由于物体内部分子的转动及振动而产生，其程度主要由物体的温度决定。

Based on the investigation on the complex radiation conditions, a new radiation temperature measurement model has been developed. The infrared multi-wavelength radiation pyrometer system has been built up consequently.

本文在研究了复杂环境中的辐射状况的基础上，提出了一种新的测温模型，并在此基础上建立了多谱段红外辐射高温计系统。

It's purpose is to develop high temperature particle spectral radiation property measurement equipment, carries out online measurement on high temperature particle, realizes the theoretical and experimental research on high temperature particle optical property, offers different temperature optical property measurement data base.

本课题来源于国家自然科学基金重点项目(编号：50336010)，红外辐射特性及传输的多尺度多参数分析项目的一部分，其目的是研制高温粒子光谱辐射特性测量装置，对高温粒子进行在线测量，通过该装置实现对高温粒子的光学特性的理论和实验研究，提供不同温度下的粒子的光学特性测量数据库。

Great comic artists assume that truth may bear all lights, and thus they seek to accentuate contradictions in social action, not gloss over or transcend them by appeals to extrasocial symbols of divine ends, cosmic purpose, or laws of nature.

尽管这些分子能够透过可见光，阳光的大部分热量？都集中在这个波段，但是它们吸收长波，从地表来的红外辐射，或者将有些辐射折射回空中。

Wavelength-selective or photoselective mulches absorb photosynthetically active radiation and transmit solar infrared radiation.

波长选择性或光选择性塑膜吸收光合活性辐射并传递太阳红外辐射。

When infrared ray irradiates to the surface of material and radiating frequency is same as material molecular frequency, the radiating energy is strongly absorbed by the material.

红外辐射是辐射物体以电磁波的方式传播内能的过程，当红外线照射到某一物体时，如果入射的红外线频率和物体分子固有频率相一致，则物质分子就会表现出对红外线的强烈吸收，吸收的那一部分能量就转化为分子的热运动，使物体温度升高，达到加热干燥的目的。

So far, most research about vectored nozzles is numerical simulations of internal flow field and manuverbility. However, research about their infrared properties, especially systematically research about spectral properties is very sparce.

目前国际上对矢量喷管内流场的数值计算，矢量喷管的机动性能的研究比较多，然而对矢量喷管红外辐射特性的研究非常少，特别是系统地研究矢量喷管壁面和出口平面的光谱辐射特性方面的工作特别少。

Such so-called Dyson spheres would, if they exist, reradiate captured energy (after some of it had been put to good use) as heat—infra-red radiation.

这种别称作戴森球壳的东东，如果它们存在，它将再辐射俘获的能量（在一些能量被充分利用之后）就像热量，例如红外辐射。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
