会计中figures of merit是什么意思

指的是: 材料的优值 或,器件的优值因子

例句‘:
The pyroelectric coefficient at 25 ℃ is 1 860 μC/(m 2·K), and the figure-of-merit of this film is 37.4 μC/(m 3·K). The high pyroelectric coefficients and the greater figures of merit of the Ba 0.64 Sr 0.36 TiO 3 thin films make it possible to be used for thermal infra-red detection and imaging.
热释电性能测试结果表明 :室温下Ba0 .6 4Sr0 .36 TiO3薄膜的热释电系数为 1860 μC/(m2 ·K) ,材料的优值为 3 7.4μC/(m3·K) ,这些结果表明 :应用溶胶 -凝胶工艺制备的Ba0 .6 4Sr0 .36 TiO3薄膜完全能满足红外探测器和热成像应用的需要

a figure of merit is a quantity used to characterize the performance of a device, system or method, relative to its alternatives. in engineering, figures of merit are often defined for particular materials or devices in order to determine their relative utility for an application. in commerce, such figures are often used as a marketing tool to convince consumers to choose a particular brand. examples * clock rate of a cpu * calories per serving * contrast ratio of an lcd * frequency response of a speaker * fill factor of a solar panel * resolution of the ccd in a digital camera * detection performance of a sonar system * noise figure of a radio receiver * the thermoelectric figure of merit, z, a material constant proportional to the efficiency of a thermoelectric couple made with the material
