- The sauna is supposed to emit radiation in the infrared part of the spectrum, which adjoins the microwave spectrum. 这种机器应该会释出光谱中临近微波的红外线。
- Whereas each CDM particle conserves its energy from then on, the baryonic gas is able to emit radiation. 虽然每一个CDM粒子的能量从此不会改变，重子气体却仍能辐射电磁波。
- Since black holes do not classically emit radiation, the thermodynamic viewpoint was simply an analogy. 既然黑洞不是经典地发出辐射，熵的观点只是一个类推。
- This is because radioactie chemicals such as radioiodine decay in a predictable way and emit radiation while that is happening. 这是因为放射性物质如放射性碘通过可预料的途径衰减并在这个过程中发出射线。
- Then, upsetting the universal belief that nothing, not even light, can escape from a black hole, he used the quantum theory to demonstrate that these miniholes (and larger ones too) emit radiation. 后来，他用量子理论证明这些小洞(还有大的)能发出射线，从而推翻了认为任何东西(光在内)都不能逃脱黑洞的普遍看法。
- What is radioactive?In the natural world, where the atomic nucleus unstable, can spontaneously emit radiation, some time into other elements atomic nucleus elements called radioelement. 何谓放射性?在自然界,凡原子核不稳定,能自发地放出射线,过一些时间变成其它元素原子核的元素,叫放射性元素。
- Temperature of the black body that emits radiation of the same chromaticity as the radiation considered. 待测灯与黑体的辐射具有相同的色度值时，该黑体所具有的温度。
- The detectors of the emitted radiation are synchronized to their specific element's sourse. 发射辐射的探测器与它们的特定元素的激发源是同步的。
- The detectors of the emitted radiation are synchronized to their specific element's source. 发射辐射的探测器与它们的特定元素的激发源是同步的。
- The detectors of the emitted radiation are synchronized to their specific element 's sourse. 发射辐射的探测器与它们的特定元素的激发源是同步的。
- They showed that the elements uranium and thorium emitted radiation that Becquerel had detected in uranium and had found to be similar to X-rays. 他们发现铀元素与钍元素都能发出辐射，贝克勒尔检测了铀元素，发现它类似于X光。
- How do they suggest that black holes may not be black, and that by emitting radiation an isolated black hole could evaporate? 为何黑洞可能并非是黑色的？一个独立的黑洞为甚麽会发出辐射，并且可以蒸发？
- It is now unlawful for factories to emit black smoke into the air. 工厂向大气中排放黑烟现在是违法的。
- A body that emits radiation. 辐射体发出辐射的东西
- Lead aprons shield people from radiation. 铅做的工作裙可使人免进辐射。
- It was buried far deeper than myth and the Oral History had led us to expect and it emitted radiation and absorbed radiation to simulate the natural character of its surroundings, a mechanical mimesis which is not surprising of itself. 正如我们所猜想的，宝库是隐藏着的，它比一个谜埋藏的还要深，只有口述的历史指引我们去想象，他在释放辐射的同时还吸收辐射，如同它附近物体的自然性质一样，使我们任何的简单的机械模仿都无法察觉它的存在。
- Radiation reached unheard-of levels. 辐射作用已达到前所未有的程度。
- Fireflies emit light but not heat. 萤火虫发光但不放出热。
- Animal bodies emit perspiration. 动物身体会出汗。
- The earth's atmosphere filters out much of the sun's radiation. 地球大气层可以滤掉太阳的大部分射线。
