结果表明原来的三参数几何亮点模型是在高频情况下未敷瓦壳体的一级近似。
The results show that the former geometrical highlight model with three parameters is approximation of one order for naked shells at high frequencies.
对于实际壳体，无论敷瓦还是未敷瓦都应采用修正的四参数几何亮点模型计算目标强度。
For the actual shells, the modified geometrical highlight model with four parameters should be used whether it is coated or not with silent tiles.
