Vortex-induced vibration is limited amplitude response, but it occurs at low windspeed with relative large amplitude, which will affect the strength and fatigue resistance of the structure.
Through analysis of the influencing factors of the environment, 9 main indices have been established in this paper, such as temperature, windspeed and relative humidity.
通过对影响室内环境的各种因素分析，确立了以温度、风速、 相对湿度等9项主要环境参数指标的评价体系。

Evaporation from Erhai Lake decreases with the increase of total cloud cover and relative humidity, and it increases with the increase of mean windspeed and sunshine duration.
