| 例句 | Converting the quantities in J to kJ permits them to be summed, yielding the total heat required: Chemistry 2019-02-14T00:00:00Z The value for gross productivity of primary producers and total heat and respiration is same as primary producers provide energy to primary consumers and secondary consumers only. Biology for AP Courses 2022-06-09T00:00:00Z The total heat taken up by the oceans over the past 150 years was about 1,000 times the annual energy use of the entire global population. Global warming of oceans equivalent to an atomic bomb per second 2019-01-07T05:00:00Z He went on to show that the total heat produced in any voltaic circuit was proportional to the electromotive force E of the battery and to the number of equivalents electrolysed in it. Encyclopaedia Britannica, 11th Edition, Volume 13, Slice 2 "Hearing" to "Helmond" 2012-04-25T02:00:53.567Z The total expenditure of heat of a man at rest must be equal to the total heat of combustion. Popular scientific lectures 2012-04-24T02:00:17.273Z The second is the actual heat efficiency, or the ratio of the heat turned into work to the total heat received by the engine. Aviation Engines Design?Construction?Operation and Repair 2011-12-04T03:00:04.777Z Indicated thermal efficiency may be defined as the proportion of the total heat of combustion which appears as work done by the explosion and expansion upon the piston. Encyclopaedia Britannica, 11th Edition, Volume 11, Slice 4 "G" to "Gaskell, Elizabeth" 2011-08-24T02:00:20.690Z Minimum thermal conductance occurs when total heat transfer through these layers is reduced to its lowest possible rate. Metabolic Adaptation to Climate and Distribution of the Raccoon Procyon Lotor and Other Procyonidae 2011-05-07T02:00:34.980Z Assuming the heat equivalent of the work to remain in the gas, he obtains expressions similar to Clapeyron’s for the total heat and the specific heats. Encyclopaedia Britannica, 11th Edition, Volume 13, Slice 2 "Hearing" to "Helmond" 2012-04-25T02:00:53.567Z The latter, it has been found, allows 92 per cent of the total heat from most sources to pass; glass and other substances transmit a much smaller proportion, and the amount varies with the source. The New Gresham Encyclopedia Volume 4, Part 1: Deposition to Eberswalde 2011-04-14T02:00:57.977Z It may be remarked that starting from the same value at 5�, for the sake of comparison, Rowland’s values of the total heat agree to 1 in 5000 with those calculated from the formulae. Encyclopaedia Britannica, 11th Edition, Volume 5, Slice 1 "Calhoun" to "Camoens" This means that the total heat remains practically the same, no matter at what pressure. James Watt When, however, the total heat waves radiated out by a body are less than it absorbs, the body gets gradually colder, and the temperature decreases. Aether and Gravitation With the softer substances, the total heat produced may be greater than with the hard ones, but, to produce the spark, the heat must be intensely localised. Fragments of science, V. 1-2 While valuable for improving the taste of foods, the main worth of sugar is as a nutritive substance; used in the preparation of foods it adds to the total heat and energy of the ration. Human Foods and Their Nutritive Value The values of the total heat observed by Regnault, as reduced by Shaw, also show a very fair agreement, considering the uncertainty of the units. Encyclopaedia Britannica, 11th Edition, Volume 5, Slice 1 "Calhoun" to "Camoens" His next step was the discovery of the total heat of steam, and that this remains practically constant at all pressures. James Watt From this it is clear that the larger proportion of total heat of the body is supplied by the muscles. Encyclopaedia Britannica, 11th Edition, Volume 2, Part 1, Slice 1 Fully four-fifths of the total heat are used up in this molecular work, only one-fifth remaining to warm the battery. Fragments of science, V. 1-2 The total heat of the steam remains nearly constant, whatever be the temperature at which the vaporization occurred. Scientific American Supplement, No. 430, March 29, 1884 Numerous investigators have studied the optical or radiant efficiency of artificial lights, i.e., the proportion of the total heat plus light energy emitted by the flame which is produced in the form of visible light. Acetylene, the Principles of Its Generation and Use A Practical Handbook on the Production, Purification, and Subsequent Treatment of Acetylene for the Development of Light, Heat, and Power The total heat developed by an ounce of zinc through its union with oxygen in the battery is also absolutely invariable. Fragments of science, V. 1-2 The sum of the two quantities is called the total heat of the steam at 100°. Scientific American Supplement, No. 430, March 29, 1884 |
