1·The mishap occurred when the single-engine aircraft was caught by a gust of wind while hovering a few feet above the ground before landing.
事故发生时，这架单引擎飞机正在离地几英尺的空中悬停准备降落，此时遇到了阵风。
2·Media reports suggest that the mishap occurred when the single-engined aircraft was caught by a gust of wind while hovering a few feet above the ground before landing.
媒体报道显示，事故发生时这架单引擎飞机正在离地几英尺的空中悬停准备降落，此时遇到了阵风。
3·Gale: refers to the average wind is greater than 6, gust wind is greater than 7 wind.
大风：是指平均风力大于6级、阵风风力大于7级的风。
4·The static wind response of the bridge is analyzed. The static wind loads and the equality loads of gust wind are derived.
就桥梁的静风响应进行了分析研究，对桥梁静风荷载和阵风等效静力风荷载进行了推导。
5·Traditional gust responses are mainly analyzed based on linear aerodynamic load calculations in frequency-domain, which is unsuitable for and the viscous and transonic flows.
传统的阵风响应主要在频域内进行分析，气动载荷基于线性方法计算，不能考虑黏性和跨声速流动影响。
