The paper introduces the basic principle of the inducement type ventilation in the province of aerodynamics : disturbed characteristic of high - speed cascade can effectively leads quiescent air around it and drive air flow, compares and analyzes the traditional ventilation type and inducement ventilation type applied in underground garage in the facets of airflow organization, practicability and economy, coming to the conclusion that the inducement type ventilation is applied to the underground garage in the facets of economy, practicality and high efficiency
摘要介紹了誘導式通風利用空氣動力學中高速噴流的擾動特性，能夠有效地誘導周圍靜止的空氣，帶動空氣流通的基本工作原理，就傳統通風方式和誘導通風方式，在地下車庫應用中的氣流組織、實用性、經濟性等幾個方面做了比較，分析認為，誘導式通風因其經濟、適用、高效的特性適合在地下車庫應用。 -
The flowfield over low - drag and long - range projectile with small attack angle is numerically studied from transonic to supersonic velocity. it provides basic work for aerodynamics characteristic of this projectile and for lateral jet interaction flowfield, and it shows this projectile can decrease drag. zonal method is tried to compute flow over projectiles and results is satisfied, but computation is much slower
系統研究了低阻遠程彈丸在小攻角狀態，低跨聲速、高跨聲速和超聲速時的非對稱繞流流場，為該彈形氣動力研究提供理論指導並為彈丸側噴流研究奠定基礎，結果顯示低阻遠程彈丸外形具有優化繞流場、減小空氣阻力的特點。
