This paper put forward an idea of real time of indoor air quality, so as to emphasize that IAQ is a variable and comprehensive factor formed by design, construction and system running.
本文提出了实时室内空气品质的概念，是强调室内空气品质是一个变量，是设计、施工和运行管理多学科、多专业综合形成的一个量。
Research results showed that the surface shape factor was not a constant value, but a variable value with the change of irrigation time, water advance distance and other factors.
研究表明同一次畦灌过程中地表储水形状系数并非恒定值，而是随灌水时间和水流推进距离等因素变化的。
