the results showed that the diurnal fluctuation of temperature and humidity had similar tendency between inside and outside of greenhouse under different weather conditions.
结果表明,不同的天气条件下,温室内外的温度和湿度的日变化趋势比较一致。
meanwhile, a diurnal fluctuation in indoor radon concentration was observed.
高温低湿环境有利于氡进入温室且浓度呈日间周期性波动。
at cloudy day, however, the diurnal fluctuation and the vertical distribution of non-ionized ammonia concentration at different water depth have little difference.
