To determine the shock and position error of an aircraft from supersonic speed to the stall area 全速度范围内确定飞机气动激波修正量
We are now exploring a method in theory to predict the vessel voyage performance of given propeller trailing edge modification 本文试图探索一种方法,从理论上预报给定修正量对船舶航行性能的影响。
4 . a new method for updating linear structural dynamic model was proposed in the paper . the modified parameters were determined by sensitivity analysis 4 .对线性结构的有限元动力模型修正问题,通过灵敏度分析,确定要修正的参数,由正交性条件和特征方程得到相应的修正量方程。
