| 微型计算机 | microcomputer A microprocessor combined with input/output interface devices, some type of external memory, and the other elements required to form a working computer system; it is smaller, lower in cost, and usually slower than a minicomputer (一个结合了输入/输出接口设备的微处理器、一些外部存储器和其它所需的要素形成的工作计算机系统；它比一台小型计算机体积小、造价低，速度通常慢于小型机。) |
| 扩散计算 | dispersion calculation The calculation of pollutant dispersion is based on the use of air dispersion models that mathematically simulate atmospheric conditions and behaviour. Dispersion models can provide concentration or deposition estimates and can be used to evaluate both existing and hypothetical emissions scenarios (污染扩散的计算是基于空气扩散模型通过数学方法来模拟大气条件和行为；扩散模型可以估计污染物的浓度或沉降量，同时可以评估现有或假设的排放情形。) |
