单词 | bolometer |
例句 | Radiation-detectors known as bolometers are vital instruments in many fields of science. Greenland's ice will melt faster than any time in the past 12,000 years 2020-09-29T04:00:00Z Normally, the South Pole Telescope’s 10-meter dish funnels extremely faint radiation from the cosmic microwave background into a camera called a bolometer. Scientists are hunting for black holes on the South Pole 2015-03-01T05:00:00Z Herschel used special light detectors in its instruments known as bolometers. End for Herschel space telescope 2013-04-29T16:06:44Z Observations taken with a bolometer along the length of a normal or wave-length spectrum, would give the form of the curve plotted on a wave-length base. Encyclopaedia Britannica, 11th Edition, Volume 13, Slice 2 "Hearing" to "Helmond" 2012-04-25T02:00:53.567Z He devised later a promising method by which the heat of the corona in different regions can be measured by the bolometer, and an outline corona afterward sketched from these results. Astronomy: The Science of the Heavenly Bodies 2012-03-17T02:01:02.630Z What the real limit of the spectrum is, is at present unknown; Mr. Langley with his bolometer, and rock-salt prisms, an instrument more sensitive than the thermopile, must have nearly reached it. Colour Measurement and Mixture 2012-02-27T03:00:13.987Z Dr. Lange, working with James Bock, now at NASA’s Jet Propulsion Laboratory, built new detectors, known as spider web bolometers, designed for studying the cosmic microwave work. 2010-01-28T07:17:00Z "The bolometer," he replied, "invented by Professor Langley." The Social Gangster They employed an aperture in the side of an enclosure at uniform temperature as the source of radiation, and compared the intensities at different temperatures by means of a bolometer. Encyclopaedia Britannica, 11th Edition, Volume 13, Slice 2 "Hearing" to "Helmond" 2012-04-25T02:00:53.567Z They may be investigated with the bolometer, an instrument invented by the late Professor Langley. Astronomy of To-day A Popular Introduction in Non-Technical Language Important experiments were indeed made on the heat of the corona with Langley's bolometer, but their upshot can scarcely be admitted as decisive. A Popular History of Astronomy During the Nineteenth Century Fourth Edition Besides the eye, the astronomers use a photographic plate, bolometer, a photo-electric cell, and other instruments. Lectures on Stellar Statistics We have a heat-measuring instrument, the bolometer, which makes the best thermometer seem Early Victorian. The Outline of Science, Vol. 1 (of 4) A Plain Story Simply Told The Astrophysical Observatory was established, in which Professor Langley has continued his epoch-making work on the sun's radiant heat with his wonderful bolometer, an instrument of his own invention. The Reminiscences of an Astronomer We have no time or space here to describe Professor Langley's "bolometer;" it must suffice to say that it seems to stand to the thermopile much as that does to the thermometer. Scientific American Supplement, No. 443, June 28, 1884 Here, at an elevation of 14,887 feet, in the driest and purest air, perhaps, in the world, atmospheric absorptive inroads become less sensible, and the indications of the bolometer, consequently, surer and stronger. A Popular History of Astronomy During the Nineteenth Century Fourth Edition They have measured not only the pressure, but also the energy of the radiation by means of a special bolometer. The New Physics and Its Evolution Second, by taking the instrument up to some such elevation as that to which Langley took his bolometer at Mount Whitney, and so to leave the densest part of the atmosphere below us. Scientific American Supplement, No. 595, May 28, 1887 By means of an ingenious modification of the electrical pyrometer, named the bolometer, valuable researches in measuring solar radiations had been made by Professor Langley. Scientific American Supplement, No. 384, May 12, 1883 Kennedy lost no time in confirming the suspicions of his bolometer as to the cause of the death of the two innocent victims of the machinations of the Clutching Hand. The Exploits of Elaine In the latter part of 1902 an extraordinary diminution was found in the intensity of the sun's heat, as measured by the bolometer and other instruments. Side-Lights on Astronomy and Kindred Fields of Popular Science Then Kennedy began carefully examining the bolometer and some other recording instruments he had, while the rest of us watched, fascinated. The Exploits of Elaine I knew it was not that which we had to fear, but the invisible rays that accompanied it, the rays that had affected the bolometer. The Exploits of Elaine As I moved over to look at the bolometer, I happened to glance into the busybody and saw that a crowd was rapidly collecting on the sidewalk. The Exploits of Elaine "A bolometer, invented by the late Professor Langley," he replied, his attention riveted on it. The Exploits of Elaine |
