| 释义 | measurement (once / 883 pages) n Taking a measurement involves figuring out how long something is or what it weighs or how fast it is. Measurements usually require something like a ruler or a stop watch. When you step on the scale to check your weight, you're getting a measurement. When you pull out a ruler and measure a piece of paper, you're making a measurement. Astronomers make measurements of how far away other planets and stars are. In the Olympics, a timer does a measurement of who's fastest, to see who won a race. Anytime you're using a measuring device to come up with a number for something, you're taking a measurement. WORD FAMILYmeasurement: measurements+/countermeasure: countermeasures/immeasurable: immeasurablest, immeasurably/measurable: immeasurable, measurability, measurably, unmeasurable/measure: countermeasure, measurable, measured, measureless, measurement, measurer, measures, measuring/measured: measuredly, unmeasured/measureless: measurelessly/measurer: measurers/measuring: measurings/unmeasurable: unmeasurably USAGE EXAMPLES“A measurement is just a number. But a visual image of what they look like, rather than their imagination, is much more motivating.” Washington Post(Dec 30, 2016) He questioned, though, whether the measurements six years later were accurate. New York Times(May 02, 2016) But the measurement of antihydrogen's light spectrum was about 100,000 times less precise than the best measurements of the spectrum for regular hydrogen. Washington Post(Dec 20, 2016) n the act or process of assigning numbers to phenomena according to a rule the measurements were carefully done Syn|Hypo|Hyper measure, measuring, mensuration seismography the measurement of tremors and shocks and undulatory movements of earthquakes quantitative analysis, quantitative chemical analysischemical analysis to determine the amounts of each element in the substance actinometrymeasuring the intensity of electromagnetic radiation (especially of the sun's rays) algometrymeasuring sensitivity to pain or pressure anemographyrecording anemometrical measurements anemometrymeasuring wind speed and direction angulationthe precise measurement of angles anthropometrymeasurement and study of the human body and its parts and capacities arterial blood gasesmeasurement of the pH level and the oxygen and carbon dioxide concentrations in arterial blood; important in diagnosis of many respiratory diseases audiometrymeasuring sensitivity of hearing bathymetry, plumbingmeasuring the depths of the oceans calorimetrymeasurement of quantities of heat cephalometrymeasurement of human heads densitometrymeasuring the optical density of a substance by shining light on it and measuring its transmission dosimetrymeasuring the dose of radiation emitted by a radioactive source fetometry, foetometrymeasurement of a fetus (especially the diameter of the head) gravimetry, hydrometrythe measurement of specific gravity hypsography, hypsometrymeasurement of the elevation of land above sea level mental measurementa generic term used to cover any application of measurement techniques to the quantification of mental functions micrometrymeasuring with a micrometer observationthe act of making and recording a measurement pelvimetrymeasurement of the dimensions of the bony birth canal (to determine whether vaginal birth is possible) photometrymeasurement of the properties of light (especially luminous intensity) quantificationthe act of discovering or expressing the quantity of something radioactive datingmeasurement of the amount of radioactive material (usually carbon 14) that an object contains; can be used to estimate the age of the object meter reading, readingthe act of measuring with meters or similar instruments samplingmeasurement at regular intervals of the amplitude of a varying waveform (in order to convert it to digital form) soundingthe act of measuring depth of water (usually with a sounding line) sound ranginglocating a source of sound (as an enemy gun) by measurements of the time the sound arrives at microphones in known positions scalingact of measuring or arranging or adjusting according to a scale spirometrythe use of a spirometer to measure vital capacity surveyingthe practice of measuring angles and distances on the ground so that they can be accurately plotted on a map telemetryautomatic transmission and measurement of data from remote sources by wire or radio or other means thermometrythe measurement of temperature thermogravimetrythe measurement of changes in weight as a function of changes in temperature used as a technique of chemically analyzing substances tonometrythe measurement of intraocular pressure by determining the amount of force needed to make a slight indentation in the cornea viscometry, viscosimetrythe measurement of viscosity triangulationa method of surveying; the area is divided into triangles and the length of one side and its angles with the other two are measured, then the lengths of the other sides can be calculated colorimetric analysis, colorimetryquantitative chemical analysis by color using a colorimeter volumetric analysisquantitative analysis by the use of definite volumes of standard solutions or reagents volumetric analysisdetermination of the volume of gases (or changes in their volume) during combination gravimetric analysisquantitative analysis by weight cytophotometrythe study of chemical compounds inside a cell by means of a cytophotometer gradation, graduationthe act of arranging in grades scalagethe act of scaling in weight or quantity or dimension mental test, mental testing, psychometric test, testany standardized procedure for measuring sensitivity or memory or intelligence or aptitude or personality etc radio observationan observation made with a radio telescope activity any specific behavior |
