| 例句 | Mr Hussain said a potent beam of light could trigger thermal or photochemical reactions which inflict lasting damage on the retina - the nerves at the back of the eye which detect light. Laser pointers: The pocket money gadget that could cause blindness 2023-09-28T04:00:00Z "Our findings support the theory that the Sun's UV rays, when strong enough, may be triggering a photochemical reaction that produces Neptune's clouds." Neptune's strange clouds are disappearing, revealing the weird seasons of the ice giant 2023-08-25T04:00:00Z These cells aren’t literally burned but are subjected to photochemical reactions that can damage them—sometimes permanently. Here’s what happens to your eyes if you look directly at the sun 2023-08-18T04:00:00Z In Jupiter’s upper atmosphere, photochemical reactions create a variety of fairly complex compounds of hydrogen and carbon that form a thin layer of smog far above the visible clouds. Astronomy 2016-10-13T00:00:00Z More than any fluctuation in emissions, heat is often what determines whether air quality will be unhealthy on any given day, because it fuels the photochemical reactions that form ozone. L.A. began 2020 with a clean-air streak but ended with its worst smog in decades 2020-12-06T05:00:00Z That’s because hotter weather speeds up the photochemical reactions that turn pollutants from vehicle tailpipes and other sources into ozone, the invisible, lung-damaging gas in summer smog. How climate change is fueling record-breaking California wildfires, heat and smog 2020-09-13T04:00:00Z Like many researchers, he’d assumed that indoor air, lacking sunlight and, thus, hydroxyl radicals, wouldn’t yield the kind of rapid photochemical reactions that atmospheric scientists like to study. The Hidden Air Pollution in Our Homes 2019-04-01T04:00:00Z They’re also planning a study into whether climate change is contributing to the smog problem, as many scientists expect, due to higher temperatures that speed the photochemical reactions that form ozone. 87 days of smog: Southern California just saw its longest streak of bad air in decades - Los Angeles Times 2018-09-21T04:00:00Z Ozone is a major component of smog and is formed by the photochemical reaction of pollutants emitted by motor vehicles, industry and other sources in the presence of elevated temperatures and sunlight. Rhode Island officials issue air quality alert 2018-05-03T04:00:00Z Ozone is a major component of smog and is formed by the photochemical reaction of pollutants emitted by motor vehicles, industry and other sources in the presence of elevated temperatures and sunlight. Rhode Island officials issue air quality alert 2018-05-03T04:00:00Z Its volatile gases drift upwards, and photochemical reactions create new carbon and nitrogen compounds. Icy heart could be key to Pluto’s strange geology 2016-10-20T04:00:00Z The key follow-up step after the exposure is to kill this photochemical reaction and so stabilize the captured shadows. Rebooting Civilization: Survivors’ How-to Guide for Restoring Technology after the Apocalypse [Excerpt] 2014-05-02T14:00:00Z Visible and ultra-violet rays are the radiations almost entirely responsible for photochemical reactions, but the most active of these are the blue, violet, and ultra-violet rays. Artificial Light Its Influence upon Civilization Contrary to most photochemical reactions, it appears that plant life utilize yellow, red, and infra-red energy more than the blue, violet, and ultra-violet. Artificial Light Its Influence upon Civilization In general, great intensities of blue light and of the closely associated rays are necessary for most photochemical reactions with which man is industrially interested. Artificial Light Its Influence upon Civilization It is impossible to rate the different illuminants in a general manner as to actinic value because the various photochemical reactions are not affected to the same extent by rays of a given wave-length. Artificial Light Its Influence upon Civilization Although there is a multitude of reactions in photographic processes which are brought about by exposure to light, these represent relatively few of the photochemical reactions. Artificial Light Its Influence upon Civilization Therefore, one illuminant may be superior to another for one photochemical reaction, while the reverse may be true in the case of another reaction. Artificial Light Its Influence upon Civilization The foregoing are only a few of the multitude of photochemical reactions and other effects of radiant energy.
