atmospheric radiation measurement | 大气辐射测量 |
chemical measurement of pollution The quantitative determination of the presence, extent or type of pollutant substances in the environment by studying the actions or reactions of known chemicals to those pollutants | 化学污染测定 (通过研究已知化学物质对污染物的行为或反应,以对环境中污染物的存在、程度或类型的定量测量。) |
measurements of pollution in the troposphere | 对流层污染测量 |
National Committee on Radiation Protection and Measurement | 美国国家辐射防护与测量委员会 |
noise measurement The process of quantitatively determining one or more properties of acoustic noise | 噪声测量 (定量测定噪声的一个或多个属性的过程。) |
physical measurement of pollution The quantitative determination of the presence, extent or type of pollutant substances in the environment using mechanical means, including optical, electrical, acoustical and thermodynamic techniques | 污染的物理测量 (定量测定污染存在的程度和类型,污染物的测定中使用的机械方法包括:光学、电子学、声学和热力学的基本技术。) |
pollution measurement The assessment of the concentration of pollutants for a given time in a given point | 污染测量 (在特定点和特定时间对污染物的集中评估。) |
sound measurement Because of the large variations in sound magnitudes, and because the human hearing sensation seems to vary in a logarithmic way, logarithms are used in measurement of sound. The sound pressure level is given in decibels (dB) | 声音测量 (由于声音的变化幅度大,且人耳的感觉似乎是以对数的方式改变,对数被用来测量声音,声压大小以分贝的方式给出。) |
stream measurement The quantitative determination of the rate and amount of flow or discharge from a natural body of running water, such as a small river or brook | 河流测量 (定量测定纯天然流水,如河流或小溪的费率,流动或排放量。) |
take measurement | 测量 M |
take measurements | 测量 M |
