文摘:系統地揭示了翼形幾何參數對機翼的空間散射特性、極化散射特性的影響規律.研究發現，在垂直極化狀態下用理論尖劈公式計算機翼后緣繞射的計算結果與實驗結果相差甚遠.提出在垂直極化狀態下機翼后緣繞射的計算必須將后緣厚度考慮在內的見解.對於水平極化，前緣散射波峰只與前緣半徑有關；而對於垂直極化，前緣散射波峰與翼形最大厚度以及最大厚度位置有關.給出前後緣散射波峰的工程估算公式，為低雷達散射截面（ rcs ）機翼設計提供依據Her appearance belongs to the fire type, has sharp type of face, there are more black than white in the pupils of her eyes, both eyes are wide apart, the ears are lower than the eyebrows, her earlobes are thick and broad, protruding internal earbone, short nose, wing of the nose is frail and a little protruding, her mouth forms a line when it is closed, the sides of her mouth is slightly turn downwards, the thickness of the upper and lower lips is even, her cheekbones are not high, and the law grain is profound
