| 释义 | chronometer noun[ C ] engineering specializeduk /krəˈnɒm.ɪ.tər/ us /krəˈnɑː.mə.t̬ɚ/ a piece of equipment that measures time very accurately精密计时计 Watches & clocks 24-hour clock against the clockidiom alarm alarm clock at/on the stroke of somethingidiom atomic clock clock hour hand hourglass lose military time minute hand movement pendulum stroke timepiece turn the clocks backphrase twenty-four-hour clock unsynchronized watchband He glanced at the astral chronometer. His chronometer showed a minute and half to blast time. The actual Greenwich time of the occurrence is calculated, and the error of the chronometer is thus determined. There was still ten seconds to go, according to the big chronometer that had been installed in the lock. With ordinary care the chronometer error can be determined in this way to within a few seconds, which is accurate enough for purposes of navigation. Examples of chronometerchronometer The entanglement of the construction and function of the gravity chronometer shows how experimentation is entangled with the practices sustaining it. The gravity chronometer is a good example of a sturdy yet sophisticated piece of apparatus. And indeed, accuracy of time measurement is the crucial prerequisite for the gravity chronometer that calibrates other reaction-time measuring devices. The gravity chronometer stands in front of the observer, who is peering intently at it. The time that the stimulus is visible is thus measured by the chronoscope connected to the gravity chronometer by the switches. Three papers address the crucial link between accessory phase chronometers and petrological information. Rather, the gravity chronometer's known regularity - which ensures accurate time measurement by calibrating other time measuring devices - is its defining feature. The falling screen of the gravity chronometer turns a switch when its opening slides in front of the stimulus. Figure 4 is a photograph of the setup in which the gravity chronometer featured. Neither presentation nor briefness is significant in this description of the instrument, the gravity chronometer's regularity and dependability are the crucial elements. But then again, the term "gravity chronometer" does not always refer to the same thing. The gravity chronometer's prior main function, brief exposure together with the facilitation of reaction time measurement within experimentation, has become an extra possibility. According to some, gravity chronometers are really tachistoscopes. The gravity chronometer is a product in which the author can take pride. For this regulatory function an opening in the screen is not required; the gravity chronometer presents no visual stimulus. These examples are from corpora and from sources on the web.
